Two male turkeys audition but fail to impress the judge (Photo: Teddy Llovet, Creative Commons license)

.

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.

next-door nature, urban wildlife, suburban wildlife, barn swallows

WITNESS astounding tricks of precision flying!

THRILL to the sight of daring aerial capers!

Come one, come ALL!

The Flying Circus is winging its way to a backyard near YOU!!

 

next-door nature, urban wildlife, suburban wildlife, barn swallowCritics are raving about this summer’s must-see event. Word to the wise, though—in addition to a lawn chair you’ll definitely want to bring some binoculars. That’s because the stars of this air show have an average wingspan of about 12 inches (30 cm). We’re not talking F/A-18 Hornets here, or even a Cessna 152. Think sparrow-sized, not Sparrowhawk.

Barn swallows (Hirundo rustica) epitomize the principle of “form follows function.” Combine a slender fuselage with long, tapered wings and a deeply forked stabilizer (aka “tail”) and you’ve got a bird made to spend the majority of waking life with wheels up. They even wear a uniform appropriate for fly-boys (and girls)—glossy chrome blue above and buff-to-rust below; similar to the colors of a U.S. Air Force Blue Angels jet.

Barn swallows are found far beyond U.S. borders, though.  You might even go so far as to call them jet setters. Six officially recognized subspecies are found in North and South America, Europe, Africa, and Asia. Generally speaking, the species breeds in the Northern Hemisphere (as far north as the Arctic Circle) and takes winter R&R in the Southern Hemisphere. Ornithologists have recorded barn swallows traveling over 7,000 miles (11,000 km) from Europe to southern Africa, and those based in the Americas cover similar distances.

next-door nature, urban wildlife, suburban wildlife, barn swallowWhether cruising inches above land or water or performing barrel rolls, loop-the-loops, spins, and stalls in mid-air, these agile flyers are crowd-pleasers. They aren’t grandstanding, though. A barn swallow’s life consists of more than playing with the physics of flight. Like the post-WWI stunt pilots of the 1920s, they’re trying to make a living.

It takes fuel to fly and the barn swallow go-juice of choice is winged insects—primarily high-octane flies, but also beetles, bees and wasps, next-door nature, urban wildlife, suburban wildlife, barn swallowmoths and butterflies, ants and termites.  Eating on the fly really comes in handy during long missions, including migration. Quenching one’s thirst, bathing, dating, and defending the home territory—they’re all done on the wing.

Historians disagree as to the origin of the term “barnstorming,” but one popular explanation is that pilots would fly through an open barn door and out the other side (they hoped) as a demonstration of their prowess and to drum up joy ride business.  Barn swallows have been known to fly in and out of barns as well—hence the common name. It’s a lot less risky for the birds, though.

Even daredevils like to have a place to call home, a chance to raise a family.  Before permanent man-made structures became commonplace, barn swallows built nests in caves or on the face of cliffs. Long tolerated by humans for reasons  both practical and aesthetic, today only one North American population holds to this tradition, in the Channel Islands off the coast of California; the rest of the fleet hangar in the rafters of open buildings or beneath porches. Bridges, especially those that span water, are particularly popular due to their proximity to crucial building materials.

next-door nature, urban wildlife, suburban wildlife, barn swallowGathering mud by the bill-full, mated pairs make countless supply runs to construct a neat cup or half-cup, depending on the location, then line it with grass, feathers, hair from the livestock living under the same roof, and any other soft, insulating materials they can find.

Once there’s a home base in the crosshairs, the bombardier gets the go-ahead to drop her payload of 3-7 eggs. The pair begin a series of aerial fueling attempts and in about a month’s time they’ve got themself a squadron of next-gen aviators.

Time to put on a show!

Frogs, including this Pacific tree frog, could use a little help as they try to survive in the 21st Century (Photo: Jacki Dougan, Creative Commons license)

.

Fifty years ago, Rachel Carson asked the world to consider a simple question: imagine springtime without birdsong.

Silent Spring addressed an unlikely subject for what was to become a best-selling book—the effect of DDT and other pesticides that persist in body tissue, becoming more and more concentrated as they move up the food chain (a process known as biomagnification). Yet nearly everyone could easily understand that their own quality of life would be diminished should they step outside one sunny May morning to find the dawn chorus had been replaced with a deafening stillness.

green treefrog (Photo: sarowen, Creative Commons license)Thanks to Carson’s courageous stand—and the subsequent public outcry—songbirds and other avian species dodged a bullet.* Now there’s another set of wild voices in the spring choir who could use a hand—the amphibians.

More specifically, frogs.

There are now over 1,800 threatened amphibian species. At least 168 species have gone extinct in the last two decades due to factors such as habitat loss, water pollution, disease, climate change, and invasive species. Additionally, many areas in the U.S. have recently experienced severe drought, and England is currently experiencing its worst drought in decades.

Many frog species depend on ephemeral (temporary) water sources for breeding since they don’t support fish that would eat the eggs and tadpoles. If the ephemeral pools dry up before the young amphibians have time to metamorphose, or if there isn’t enough rain to create pools in the first place, it can result in a missed generation… and a fragile future for frogs.

Frogs are essential to the health of wetland, riparian, and coastal ecosystems. Tadpoles feed on algae, preventing blooms that can reduce oxygen levels. Frogs consume millions of insects each year, including mosquitoes and ticks carrying diseases that threaten the health of humans, their companion animals, and livestock. A wide variety of wild mammals (raccoons, opossums), birds (herons, hawks, geese), and reptiles (snakes) rely on frogs as part of their diet.

April 28th was the 4th Annual Save the Frogs Day, established to raise awareness and funds for amphibian conservation. Since many frog species are comfortable living in cities and suburbs, I thought I would pass along suggestions for homeowners who would like to offer some hoppin’ hospitality, courtesy of yesterday’s event organizers:

1.    A Wet Welcome Mat

Fall and spring are the best times to create a permanent oasis for frogs. Kits are available at many garden and home improvement stores, or simply use a container or dig a hole that is deep enough (at least 1 foot at one end) and line it with sand or a flexible plastic liner before adding water.  Keep in mind, you must provide a sloped ramp so the frogs can get out easily.  Slope the liner or build one out of rocks to gradually allow the frogs to get to ground level or out of the pond. (Some nurseries also have floating devices for swimming pools that can allow amphibians who might jump in a way out.)

Don’t clean the water. In fact, add floating plants such as lily pads or leaves to provide cover. Refill slowly and carefully if water levels get low.

Don’t put fish in your pond, as they will munch on your tadpoles and frogs.

2.    Shade & Shelter

Place your pond in a shady spot, preferably surrounded with native plants to attract a tasty bug feast of ladybugs, bumblebees, and other pollinators to also help beautify your yard. You can stack some rocks or turn over a half of a flowerpot beside the rim of the pond to give your frogs a place to sit and eat their lunch as it flies or crawls by.

Don’t use pesticides or weed killers. Amphibians absorb water—and any chemicals in it—through their skin. Pesticides and weed killers can run off from land into water and can be lethal to amphibians. Certain weed killers also can alter hormones, changing male frogs into females and reducing the potential of frogs to perpetuate thriving populations.

4.    Patience, Grasshopper

Don’t be tempted to relocate frogs from other areas or stock your pond from pet stores. You may introduce diseases or invasive species and domestically raised frogs will not necessarily adapt to wild habitats. If you build it, frogs will come.

5.    Look & Listen

Become a frog watcher. You will appreciate these wonderful animals more if you can see them in action, and you can help their conservation in the process. The National Wildlife Federation’s Wildlife Watcher program allows citizen scientists to contribute to a growing database of North American wildlife, learn about the animals living in their region, and build a printable checklist of sightings.

* Although the focus of this post is frogs, wild birds still face many challenges and threats to their long-term survival. You can check out one such hazard here. Others will be addressed in upcoming NDN posts.
