Hammers and Hydrangeas

Sometimes green means stop, look, and pay attention.

.

Productivity.  A word that has long enjoyed favored status in U.S. culture. Americans are always trying to do more work in less time so we can… do even more work. We purchase time-saving apps and appliances and then fill the promised free-time that closed the deal with new projects and expectations.
.
As the saying goes, when you’re a hammer everything looks like a nail. Of course, that assume you stop the work of pounding away occasionally to look around.
.
I aspire to a zen “be here now” life but most days I miss the mark by a wide margin. Instead, I hammer down each nail on my to-do list, usually thinking about the next task or the one after that before completing the current one (and often ending up with a swollen thumb as a result). Yesterday was no exception.
.
Until, suddenly, it was.
.
Exiting my car with plastic shopping bag handles queued up along my forearms I charged down the sidewalk, mental blinders on, jaw set. Still, I did notice the row of tall limelight hydrangeas that hug my red brick building slouching beneath their load of heavy, fragrant, pale chartreuse blooms buzzing with activity.  “Honey bees,” I assumed dismissively, since a nearby restaurant keeps several hives, and continued on without breaking my stride.
.
Then I was blinded by the light of a sunbeam reflecting off an iridescent copper-green carapace.
.
I stopped in my tracks, oblivious to the increasing numbness in my hands, and watched one green June beetle (Cotinis nitida), then several more, stumble drunkenly around and through the blossoms. Glancing at other blooms I saw all kinds of colorful insects had shown up for the banquet, including other beetles and bees, butterflies, moths, flies, spiders, and wasps.  The realization that I was, yet again, missing my life for the sake productivity hit me over the head like a ball-peen.
 .
Time to take a deep breath and smell the hydrangeas. I rushed inside, left my groceries in a heap on the kitchen table, hurried back downstairs, out the door…
 .
and…
             slowed…
                                 waaaaay…
                                                          down.
.
I spent the next hour losing track of time while I conducted an informal census of bug life in the flower gardens around my building and neighborhood. My goal was enjoyment, not identification. Eyes opened wide. Really seeing.

Headbanger

 

Male downy woodpecker (Picoides pubescens)

Rushing out the door, I went over the list in my head. Workout pants and layered tees—check. Running shoes—check. Coat, hat, gloves—check. Keys and sunglasses—check. MP3 player—check. Everything was in order as I pulled out of the driveway.

Or so I thought.

Fifteen minutes later I pulled into a parking space at the Power Valley Conservation Nature Center, a 112-acre oasis in suburban St. Louis created by the Missouri Department of Conservation with hilly trails perfect for raising my heart rate for 30-40 minutes. But as I stepped out of the car and began to gather my gear I realized with dismay I’d left behind a critical component—my earbuds.

The thought of a run without my workout mix, and without any caffeine in my system either, was disheartening. I need the motivation of a musical pulse. But I didn’t have time to go back to the house so I set off anyway, prepared to suffer.

About 10 minutes later I realized I was running to a faint drumbeat. At first I thought someone who had NOT forgotten their audio equipment had the volume on their iPod turned up to 11. Once I realized the thumping came from the woods themselves, though, it wasn’t too long before I spotted the drummer, dressed more appropriately for jazz than heavy metal in the stylish black-and-white houndstooth jacket and jaunty red cap of a male downy woodpecker. In spite of the bird’s diminutive size—no more than 6” from head to tail-tip and weighing in at an ounce or less—his wardrobe set him apart on that overcast day from the slate-and-silver hickory bark backdrop.

Downy’s are capable of making a noise disproportionate to their size. When a woodpecker is looking for a mate or claiming a territory, the sound of drumming needs to carry; building a nursery cavity using a beak as a jackhammer isn’t quiet either. But if you’re in the woods and the beat is more bongo than bass, hunger is probably acting as the drummer’s muse. A gentle tap, tap, tap betrays hollow spots beneath the bark where wood-boring insect larvae wait.

Once dinner has been detected, things get… interesting. That short chisel of a beak hardly prepares you for what’s inside—like many other woodpeckers, the downy has a barbed, sticky, and flexible tongue so long it wraps around the skull when at rest. If ever there was a bird ready-made for rock ‘n roll, it’s the woodpecker. Gene Simmons got nothin’ on these headbangers.

The whole tone of my morning changed in an instant. It’s so easy to carry a personal soundtrack wherever I go that I forget about everything I normally tune out when I turn up the volume. As a result of my oversight, I suddenly had a standing-room-only ticket to a great live performance, one I would surely have missed had this excursion proceeded according to plan.  My run could wait. I stayed for several encores and gave that downy an enthusiastic round of applause as he flew off toward his next gig.

Runner-up

.

I don’t know what American grade school kids are being taught these days—I left Oakville Elementary a couple of decades ago (okay, fine—several decades ago) and since I haven’t had kids of my own I don’t have access to 21st century homework assignments. But I’ll go out on a limb here and bet that most of them know the bald eagle (Haliaeetus leucocephalus) won the 1782 version of American Idol, and that it did so by edging out celebrity judge Benjamin Franklin’s favorite contestant, the wild turkey (Meleagris gallopavo).

That long-ago contest had little in common with the popular modern day version of reality TV. For one thing, neither bird has great pipes. Citizens were never asked to call or text in their votes. Also, the bald eagle has held on to national fame longer than fellow white-headed winner Taylor Hicks, while the turkey hasn’t exactly proven the voters wrong by, say, winning an Academy Award, Jennifer Hudson-style.

On the other hand, we don’t set aside a day each November (or any month, for that matter) on which the eagle takes center stage.  So in honor of Thanksgiving, I’d like to briefly sing the praises of the runner-up… and not just as the star performer at a holiday dinner.

Shortly after Congress immortalized the eagle on the Great Seal of the United States, Franklin shared his disappointment and misgivings over their choice in a letter to his daughter. Given the sparse pelt on his own pate, one might expect ol’ Ben would view the bald eagle as a kindred spirit, or at least harbor a bit of sympathy. Instead, his criticism was as harsh as any doled out by Simon Cowell, describing our new national symbol as “a Bird of bad moral character” who “does not get his Living honestly,” preferring to sup on rotting fish or, worse yet, stealing fresh seafood from more industrious raptors like the osprey (Pandion haliaetus). What’s more, Ben argued the eagle is cowardly, evidenced by how easily it can be driven away by much smaller birds defending their nests and offspring. Not exactly the role model image our fledgling country hoped to cultivate.

The turkey, according to Franklin, is “in Comparison a much more respectable bird,” a “true original Native of America” and a “Bird of Courage” who “would not hesitate to attack” any invader and defend his home turf.

This description might not square with your expectations after years of holiday stories featuring dim-witted, less than inspiring  Butterballs-to-be but the domestic turkey is but a pale and passive imitation of the real-deal.

Wild tom turkeys (as the males are called) will most definitely defend their breeding territory against potential rivals. Large and heavy, they are unexpectedly agile flyers, aggressive fighters, social, sometimes playful, intelligent, and adaptive.  To my knowledge they’ve never been accused of theft or caught dining on carrion (their omnivorous diet consists primarily of acorns and other nuts, seeds, fruit, buds and leaves, insects and the occasional small reptile or amphibian).

As far as moral character goes… well, you know rock stars. Toms strut their stuff in a flamboyant palette of iridescent red, green, purple, copper, bronze, and gold feathers worthy of Adam Lambert. No piercings or tattoos, but oozing cool with a Beat-worthy statement beard of stiff bristles starting just above the wishbone, wattles (flesh hanging from the head and/or neck), caruncles (fleshy growths on the head), snoods (long fleshy object draped across a tom’s beak), spurs and other body art. Their ladies, in keeping with general avian fashion trends, tend to be more conservatively dressed but they can strut like a runway model  when warranted, complete with long legs and outlandish makeup. Out of the spotlight, turkey hens are attentive mothers to their precocial offspring, in contrast to the menfolk, who are polygamous absentee fathers.

(Male bald eagles, it must be said, are actively involved in their children’s upbringing; given his own reputation, Ben might have been well served to heed the old saying about people who live in glass houses before he cast the first stone.)

Like the bald eagle, wild turkeys experienced a perilous decline in their numbers during in the last century, due to overhunting and habitat loss (rather than DDT exposure, as was the case for so many of our birds of prey).  Game agencies took action to protect the species and have been successful in helping the population rebound. So much so, in fact, that turkeys have not only returned to rural fields, pastures, and woodlands but have begun to tour in many major metropolitan areas as well.  In some parts of the country spotting a flock of wild turkeys foraging near a highway, hanging out downtown, or feasting at a backyard bird feeder is no longer a novelty.

That means a growing number of Americans now have a ticket to see  this national treasure up close and personal more than once a year, and at venues other than a serving platter.

For that, I am thankful.

Size matters

Next-Door Nature, toucan, song sparrow, beak size

When you’re trying to stay cool without air conditioning, it helps to carry a radiator on your face, large or small (Photos: Ame Otoko and Cephas, Creative Commons license).

.

A scientists’ work is never done.

That’s because there’s always another layer to peel away, another stone to turn, another angle from which to view the situation.  Case in point—nearly 200 years ago, Charles Darwin made the connection between the size and shape of a finch’s beak and the availability of the seeds they eat; to this very day, no one has been able to produce evidence that undermines his observation and the conclusions he drew from them.

But what if there’s more to a beak than meets the eye?

That’s the question raised by Russell Greenberg of the Smithsonian Conservation Biology Institute. His theory—that beak size may also be an adaptation to temperature regulation and water conservation—has been bolstered by data from two recently published studies.  [Data collected, in part, by a newly minted PhD named Ray Danner. Ray just happens to be a member of my own adopted extended family, and if that name sounds vaguely familiar… well, regular NDN readers may remember that not too long ago I was bragging about another member of this ornithological power couple, Ray’s wife, Dr. Julie Danner.]

black-tailed jackrabbitSome years back, Greenberg noticed a difference in size between the beaks of sparrows living in salt marshes and those of sparrows settled just a kilometer or two further inland. Then a paper published in 2009 reported toco toucans (Ramphastos toco) may lose as much as 60% of their body heat through their long bills, based on thermal imaging and similar to the role played by the large ears of both elephants (Elephantidae) and jackrabbits (Lepus spp.). While many ecologists assumed toucans were a special case, Greenberg wondered—might other birds have evolved larger or smaller beaks to discharge or conserve heat as well?

He chose to test his hypothesis by applying thermal imaging to a subject with a much less prominent proboscis—the song sparrow (Melospiza melodia).  Native to North America, everything about these feathered minstrels is miniature compared to their South American kin. The toucan weighs in at 1-2 pounds (the large bill doesn’t actually tip the scale as much as you might think since it’s mostly hollow) while at 0.4—1.9 ounces the song sparrow is definitely a featherweight.

In the first study, two subspecies were examined. On average, the beak of an Atlantic song sparrow was found to have 17% more surface area than that of the eastern song sparrow, although both birds have similarly sized bodies. Based on the Greenberg team’s calculations, the Atlantic sparrow loses 33% more heat than it’s inland neighbor. The finding suggests beaks may play a role in thermoregulation for a wide variety of bird species.

The ability to stay cool when the ambient temperature rises is critical to survival, but how one gets rid of the excess heat is just as important.  Birds don’t sweat—they pant… and lose not just heat but water in the process. This summer, residents across the U.S. have been reminded just what a precious resource water can be, and never more so than for all the creatures without easy access to a faucet.  Greenberg and his colleagues suggest that a bird’s beak can function like a radiator, releasing heat without losing water. The Atlantic sparrow’s larger bill saves the bird about 8% more water than the smaller beaked eastern sparrow. That may not sound like much but during a hot, dry summer it could be a significant survival advantage.

The second study examined museum specimens of song sparrows collected on the other side of the continent, along the California coast. Sure enough, as maximum temperatures increase, so did beak size… with one caveat.  When the maximum temperature was higher than 98°F (37°C) beaks got smaller… just as was predicted by the original hypothesis. You see, if you took a song sparrow’s temperature the thermometer would read about 105°F (41°C). When the air temperature exceeds the bird’s own temperature, as it does in some regions, a larger beak could actually begin to absorb heat.

While the Smithsonian group has demonstrated a connection between climate and beak size, there’s still plenty of work to be done. For the new hypothesis to garner support, scientists need to see data that ties survival of wild birds to beak size-related heat dissipation.

Meanwhile, the fact that diet influences beak size and shape hasn’t changed—Darwin can continue to rest in peace. But as so often is the case, the more we discover the more we realize just how rich and complex this world and its inhabitants are … even an Earthling as seemingly plain and simple as a sparrow.

Border battles

 .

Last Sunday morning I unexpectedly found myself sitting ringside for a brief but furious brawl. Two male red-bellied woodpeckers (Melanerpes carolinus) were having a boundary dispute that started with an argument over some shrubbery then escalated into a full-on aerial assault. Colliding mid-air, they grasped one another by the feet and were so intent on punching, pecking, and plucking, the adversaries flew thoughtlessly over the nearby road directly in front of my car. Luckily, I was making my way slowly along the otherwise quiet suburban street, so I was able to stop and watch.

With my windshield serving as an impromptu HDTV, the smackdown aired for all of 45 thrilling seconds and then, as if in response to a referee’s break command… it was all over.  Each fighter retreated, shouting insults over his shoulder as he returned to his corner.

male and female RBW by Jason Paluck, Creative Commons licenseRed-bellied woodpeckers (let’s just shorten that to RBWs, shall we?) are a medium-sized bird—just over 9” (24 cm) from chisel beak to stiff tail tips with a 13-16” (33-42 cm) wingspan. Like many North American woodpeckers, they wear a black-and-white houndstooth jacket, but their bright red Mohawk (males sport a full forehead-to-neck cap while females wear an abbreviated version) sets them apart. It’s also the reason these birds are so often misidentified as the similar-sized red-headed woodpecker (Melanerpes erythrocephalus), although once the difference is pointed out the mistake is rarely repeated. RBWs take their name from a subtle scarlet stain on their buffy belly.

red-headed vs. red-bellied woodpeckers by Laura Gooch and Jason Paluck, respectively (Creative Commons license)Year-round residents in U.S. wetlands, river bottoms, woods, and wooded suburbs from the Midwest east to the Atlantic coast, RBWs are omnivorous, consuming all manner of  insects, nuts, seeds, sap, and fruit. They store surplus food in various nooks and crannies and, since they don’t migrate, their larders come in handy during winter. This species employs gender-specific foraging strategies—males search for sustenance primarily along bole while females spend the bulk of their time on the boughs.

Biologists don’t often venture out on a limb to officially identify any non-human behavior as play, but I’ve notice the profession has loosened up a bit on this issue over the past decade or so, thankfully. One example of this trend was a description of RBW behavior I read recently. This species will periodically engage in swift, nimble, and unpredictable forest flights, complete with many direction changes to dodge trees, and accompanied by constant excited chatter. The author of this resource was quick to explain that the activity probably has a practical application in that it helps youngsters practice evasive maneuvers that would come in handy should predators be lurking about. However, and surprisingly, the expert also admitted the birds seemed to be having fun.

male red-bellied woodpecker in nest (Photo- Frederick Knapp, Creative Commons license)RBWs are monogamous—for the extent of a breeding season, that is (so perhaps it would be more accurate to say they are serial monogamists)—and both are actively involved in raising young.  They nest in hardwood and pine trees, along with the occasional fence post, by excavating a cavity or stealing one from other birds. What goes around comes around, though—or so says a timeworn adage; RBWs often lose their precious nest holes, in turn, to European (aka common) starlings (Sturnus vulgaris).

Assuming the pair can hang on to their home, the female lays two to six white eggs on a cushion of wood chip construction debris and incubates them for 12 days. The hatchlings are altricial, meaning they begin their lives naked, blind, and helpless. They don’t waste any time growing up, and are ready to leave the nest for a first tentative flight when they are 24—27 days old. Depending on the region, the adults may raise from one to three broods in a season.

red-bellied woodpecker at feeder (Photo: ehpien, Creative Commons license)Defending the homestead is a top priority during the child-rearing seasons, especially if the ‘hood includes a well-tended feeder (a gold mine for species able to digest seeds or suet). Even though most bird nestlings can’t tolerate seeds and need a diet composed largely of insects, when Mom and Dad can grab a high-calorie meal from the avian equivalent of a fast-food restaurant, they have extra time to hunt for the more illusive foods their offspring need to develop properly.

Since RBW territories range from 3 to 39 acres protecting the perimeter is far from a simple task, especially when feeding yourself and your family is a full-time job. So, naturally, breaches occur… but everyone trespasses and is trespassed against.  Border skirmishes are common but they rarely result in bloodshed. Research tells us that’s due, in part, to the fact that the intensity of defense behavior tends to decrease as an animal moves away from the center of its territory. Put another way, property rights become less important the farther you are from home. In most cases, both combatants throw in the towel long before there’s a knock-out.

Tangled up in blue

.

Happiness is a shy little bird. Hiding from sight in life’s nooks and crannies, impossible to find if you look but then it darts out and lands on your shoulder just when you least expect it. It sidles up beside you like a pickpocket on a crowded street, soft and silent as wings brushing against your lapel. Hardly even noticed until something or someone causes it to flush in a flurry of feathers from beneath your jacket, taking with it a sizeable chunk of your heart. Try to grab hold as it flies away and the thief proves as elusive as dreams upon waking, slipping through your fingers like a shadow, like quicksilver.

The concept of happiness has been flitting in and out of my brain and my life for a couple of weeks now. My birthday earlier this month may have provided the initial impulse. This wasn’t a major milestone year, I’ve got too much on my plate these days to leave much room for cake, plus I’m living in a new town and don’t know many people yet… but I did take a little time to acknowledge the day and do some thinking. December 31st may be the culturally accepted time to contemplate one’s short- or long-term past and make plans for the year to come, but my inner-Pagan knows the vernal equinox is the true start of a new trip around the sun. Besides, I’m not much for following the crowd. I was the kind of kid who would disassemble all the board games in the house, shuffling the tokens and cards to make up my own game with my own rules.  So I like the idea of a personal calendar that begins in April, and a personal New Year’s Eve for reviewing said year is also appealing. Later that same week, two unanticipated events provided additional incentive to ponder the nature of happiness.

Then again, maybe I’ve had happiness on my mind because the bluebirds have returned.

Mountain bluebird pair

This year, I’ve been watching eastern bluebirds (Sialia sialis) each morning while my terrier-boy practices his soccer moves on a squeaky red rubber ball. At other times in my life, while living in other parts of the U.S., I’ve watched spring come to town on the wings of both western and mountain bluebirds (S. Mexicana and S. currucoides, respectively).  A feathered piece of sky flashing across the landscape on shallow wing beats can lift a heavy heart and lighten my mood.

Members of the Turdidae family (aka thrushes), bluebirds are related to that other famous spring harbinger, the American robin (Turdus migratorius). All three Sialia species are easy to spot and identify even though, as fruit and insect eaters, they don’t visit seed-filled feeders. The males are clad in some combination of blue with red and/or white; their mates wear less conspicuous versions of the same plumage.

Efforts to ensure this popular bird’s continued breeding success began with the recognition that they were struggling in the face of competition from introduced species such as the European starling (Sturnus vulgaris) and house sparrow (Passer domesticus), as well as reduced access to nesting habitat. Happily, by building, installing, monitoring, and maintaining special nest boxes, handy men and women across the U.S. have proven crucial to the species’ recovery.

Bluebirds have long symbolized cheerfulness, health, prosperity, and renewal, although I’m not sure why. Their lives are far from easy or free of conflict. Males battle over breeding territories, chasing one another at breakneck speeds, grabbing each other by the feet in mid-air, smacking opponents with their wings as they try to pull each others feathers out with their beaks. They must defend nest cavities or boxes from a host of other birds, many of which are substantially larger. Once a nest site has been established, a mated pair may produce 2-4 broods per season—a task that requires foraging non-stop during daylight hours to find enough food to keep themselves and their offspring fed. If that were not challenge enough, bluebirds undertake an exhausting and hazardous migration of up to 2,000 miles each autumn and spring.

Despite these hardships, some sources claim the connection between blue birds and happiness is global (albeit focused on bird species indigenous to each country or continent). One thing is certain—the notion, however it began, has been perpetuated by Hollywood and on the radio. I have to wonder if any other bird has been as popular with songwriters and singers, starting with  Bluebird of Happiness, a hit song in the early 1930s that may have ushered this phrase into the popular vernacular.  Judy Garland probably helped things along when she sang of bluebirds flying Somewhere Over the Rainbow. For those who like both their birds and their grass blue, there’s Lester Flatt’s Bluebirds Singing For Me. Paul McCartney, Buffalo Springfield, Bonnie Raitt and, more recently Christina Perri and Adam Green all feature bluebirds on their playlist. Sara Bareilles’ poignant Bluebird tells of a kind of migration, but my own favorite blue bird tune, Birdhouse in Your Soul by They Might Be Giants, transports me to a happy scene, sitting at the kitchen table of a remote lake house in a faraway forest.

Emotions can be tricky to articulate and color can help paint a clearer picture. I get that. If a friend says she’s in the pink or he’s green with envy, you know the score even without the details (although you may still want to hear them). Red is, of course, the color of both anger and passion (maybe that’s why one so often leads to the other). Blue is happiness—at least, that’s what a little bird told me. But is it? If I say I’m feeling blue you’re not likely to picture me in your mind’s eye singing in the rain ala Gene Kelly.

How did a single color come to represent both sides of the spectrum, sadness and joy? I wish I knew, but I’m not sure it matters in the long run. I do know this: happiness prefers an open palm to an iron grip. It doesn’t do well when caged; like a wild bird, it needs to be free to come and go as it chooses. A full life requires both kinds of blue plus all the other colors and creatures, winter and spring, parting and reunion. If you want to have happiness in your life you must be willing to risk losing it, trusting that it will return as surely as bluebirds in April. That’s the trade-off, the price you pay for the flutter of wings in your heart and stomach.

But worth every penny.

Blinded by the light

.

I’ve never been much for following trends and this week was no exception. I’m writing from an altitude of 10,000+ feet and, as I fly west-to-east across North America on my way home from a conference in Fort Collins, Colorado, millions of birds are winging from south-to-north along time-honored sky routes.

Warbling vireo, warbling

Spending time west of the Mississippi flyway provided me with a chance to get reacquainted with some favorite species from when I lived in New Mexico. I got a heads-up on who to look for using a great resource—the e-Bird Migration Forecast. For example, the pace of this record-breaking early return of migratory birds is expected to slow somewhat during the last gasp of March due to unfavorable winds, but Bell’s and warbling vireos (Vireo bellii and Vireo gilvus, respectively) began to arrive out West a couple of weeks ago. By the time I get back home to the southeast there’s a good chance any number of wood-warblers will already be there including one of the more easy-to-identify species, the black-and-white warbler (Mniotilta varia). e-Bird’s experts predict it shouldn’t be too long before blue-gray gnatcatchers (Polioptila caerulea) come to my neighborhood since they’ve been spotted as far north as Maryland already.

Sadly, one of the best places to see a diverse array of migratory birds is at the base of tall buildings. This is also one of the worst places because the birds you’ll find are likely to be dead or injured. Others are simply too exhausted to fly any further which makes them very vulnerable to the scavenging species who have learned that migration season in the city means food is literally falling from the sky. One expert estimates as many as 100 million birds die in collisions with buildings every year. Songbirds are particularly susceptible to this hazard.

At night, migrating birds seem to be strongly attracted to artificial light and once inside the neon and fluorescent glow they’re reluctant to return to the darkness. High-rise glass and light are a deadly combination for these travelers—those that don’t collide with the buildings fly around and around as if caught in a sci-fi tractor beam until they drop from fatigue.

In some cities, bird-loving volunteers organize rescue teams who arrive before sunrise to beat gulls, free-roaming cats, raccoons, coyotes, and others to the survivors. The injured are transported to wildlife rehabilitators for care, the dead are collected and counted.  The Chicago Bird Collision Monitors have reported finding an average of 5,000 birds on the streets and sidewalks during the annual spring and fall migrations. In Toronto alone the Fatal Light Awareness Program (FLAP) has documented bird-building collisions for over 140 species.

No one wants to add to his or her birding life list this way.

Thankfully, FLAP has some simple suggestions for reducing the carnage:

  • Turn off the office lights and close the blinds when you leave at the end of the day, and ask your co-workers to do the same.
  • Talk to the building’s maintenance supervisor and cleaning staff to explain their critical role in creating a bird-friendly building.
  • If you notice dead and/or injured birds on the ground around your building, consider organizing a group of coworkers to serve as rescuers and team with wildlife rehabilitators in your area.
  • FLAP recommends keeping a supply of paper grocery bags on hand for rescues. Once a bird has been placed inside the top can be folded over and stapled shut. This does not create an air-tight seal so there’s no need to poke air holes in the bag, and the darkness inside the bag will help calm the bird so it doesn’t injure itself further.

Before you forget, why not leave a reminder on your computer screen or near your office door? If you make it just a little harder to see migratory birds in the urban jungle you may end up making it just a little easier to continue seeing migratory birds in the future.

Wobbling waxwings

I recently came across a report that cedar waxwings (Bombycilla cedrorum) have returned to Texas. Every time I hear someone mention this species I’m reminded of  my days as director of a wildlife center in Houston. For a few weeks every year the waxwings would show up by the cardboard box-full and the rehabilitation clinic would turn into… well, a different kind of rehab center.

With their handsome, distinctive plumage, even a newbie birder can easily recognize this species. Their yellow tail- and red wing-tips look as if they’ve been dipped in sealing wax—thus the name. With a range that covers much of North America, waxwings aren’t rare but they’re not as common as some of our iconic backyard birds, so it’s always a bit of a thrill when they’re in the neighborhood.

Cedar waxwing and chick (Photo: Alan Huett, Creative Commons license)They’re one of only a handful of avian species in the U.S. and Canada whose diet is composed largely (but not entirely) of fruit, a useful characteristic when one shares a breeding territory with brown-headed cowbirds (Molothrus ater) and other nesting parasites—females who don’t bother to build a nest of their own. Instead, they leave their eggs in the nests of other birds and the cowbird chicks are cared for like biological children. In fact, the foster nestling normally out-competes the surrogate’s own offspring when food is being passed out but the high-sugar diet provided by waxwing parents, while perfect for their own kids, causes the cowbird to waste away.

Waxwing adaptability has allowed them to benefit from the introduction of non-native fruit-bearing plants used in urban and suburban landscaping. For example, they seem to love honeysuckle… and it shows. The red pigment in the exotic vine’s berries can turn the bird’s canary tail-tips bright orange, a plumage change birders and ornithologists first began to notice in the 1960s.

Once they’ve gobbled up every last berry, they move along without a backward glance.

Unless the fruit is spiked.

It’s not a matter of someone trying to contribute to avian delinquency. From late autumn until plants have produced new spring and summer crops, last season’s berries, drupes, drupelets, pomes, and other sweet seed containers hang on, growing inceasingly less… fresh, shall we say. Temperature fluctuations and the presence of wild yeasts often will cause fruit to ferment in situ. Migration and colder temperatures make for voracious birds and the waxwings are carbo-loading as fast as they can swallow. They don’t seem to notice some of the snacks pack a punch. When you weigh slightly more than an ounce, the alcohol content doesn’t have to be very high to knock you for a loop. Next thing you know, birds are careening around on the front lawn like New Year’s Eve.

Good Samaritans across the county scoop disoriented birds into cardboard boxes and head for the nearest wildlife rehabilitation center. There, the birds are given a head-to-toe, beak-to-tail examination. Most of the patients are simply allowed to safely sleep it off in a warm, dark room before being released to continue their travels… although they probably set out with a doozy of a headache.
