Tipping Point

Imagine having this beautiful exotic bird at your backyard feeder on a regular basis.

One wild parakeet is a joy to watch. Two are nice, too. But how many constitute a nuisance?

Rose-ringed parakeets (Psittacula krameri) are native to Asia and Africa and popular as pets in Europe, especially because they can mimic the human voice. However escaped rose-ringed parakeets are now feral in many European cities and the seventh most numerous bird in London gardens (backyards). Counts conducted a decade ago put Britain’s feral parakeet population at 30,000 birds.

In large flocks the parakeets are noisy and hungry, even voracious. They shout everywhere they go.

“Rose-ringed Parakeet (Psittacula krameri)” from xeno-canto by Timo Tschentscher. Genre: Psittacidae.

Ironically, the birds have reached two tipping points. Their population is increasing in urban Europe but declining in their homeland, India, where they’re trapped for the pet trade.

How many is too many in Europe? How few is too few in the wild?

Read more about the U.K. population at CBC news and on the RSBP website.

p.s. The bird pictured at the feeder is female and not nearly as colorful as the male, below. The males have rosy rings on their necks.

Looks A Little Different

There’s something odd about this avocet.

The ones we see in Pennsylvania have orange heads in breeding plumage …

… and white heads in basic (winter) plumage.

The bird at the top looks different because he’s a pied avocet (Recurvirostra avosetta), native to Europe, Asia and Africa.

Our avocets are “American avocets” (Recurvirostra americana).

Fortunately we can identify both birds as avocets. All we need is the right adjective.

Do You Have A Hobby?

Do you have a hobby?

Jos Zwarts of the Netherlands has a hobby of drawing birds. He drew this bird. It’s a hobby (Falco subbuteo).

Native to Europe and Asia, the Eurasian hobby is a bit larger than a merlin. North America has kestrels, merlins, peregrines and gyrfalcons but nothing like a hobby.

Sleepy Eyes, Thick Knees

There’s a page in the Birds of Europe that shows a “curlew” unlike any found in the United States. In fact he’s not related to them.

The Eurasian stone curlew (Burhinus oedicnemus) and his Burhinidae relatives have been hard to classify. They somewhat resemble bustards so were placed in the crane family, Gruiformes, but now they’re with the shorebirds in Charadriiformes. Even so, stone-curlews are far away in the family tree from our curlews, the true sandpipers Scolopacidae.

Eurasian stone-curlews breed in dry open places in Europe and spend the winter in Africa. They’re nocturnal birds the size of whimbrels with thick knees and large eyes that look perpetually sleepy. At night the stone curlew sings a loud wailing song.

“Eurasian Stone-curlew (Burhinus oedicnemus)” from xeno-canto by Stanislas Wroza. Genre: Burhinidae.

We have no stone-curlews or thick-knees in the U.S. but they are in our hemisphere. The nearest species lives in Central and South America, the double-striped thick-knee (Burhinus bistriatus).

Spoonbills Here and There

A bird this unusual must surely be from the tropics, but not this one.

The Eurasian spoonbill (Platalea leucorodia) is a large white wading bird with black legs and a spatulate bill that’s black with a yellow tip. In breeding plumage they have feather crests and yellow chins. Click here for another view.

Spoonbills live in fresh and saltwater wetlands where they hunt for prey by sweeping their long bills side to side below the surface, snapping them shut when they feel prey close by.

Amazingly this spoonbill nests in both temperate and tropical zones. Though they’re sparse in Europe, their range extends to Africa and wide swaths of Asia (see map). Four hundred years ago Eurasian spoonbills disappeared from the British Isles. Happily, they returned to breed in the marshes of Norfolk County in 2010.

Of the six spoonbill species on Earth, all but one are white. The pink one lives in our hemisphere, the roseate spoonbill (Platalea ajaja).

The Rarest Warbler in North America

Kirtland’s warbler (Setophaga kirtlandii) is one of the rarest songbirds in North America. I have never seen one. Today’s the day.

This morning nine friends and I are embarking on a Michigan Audubon Kirtland’s Warbler Tour to visit its breeding grounds near Grayling, Michigan.

The Kirtland’s warbler is a habitat specialist, breeding only in young jack pine forests and almost exclusively in this area of Michigan. When the forest became fragmented and no longer burned to regenerate, the warblers’ population crashed in the 1960’s and early 70’s. Listed as endangered, it recovered from a low of 400 individuals to an estimated 5,000 birds thanks to careful forest management and control of the brown-headed cowbird, a nest parasite.

Without human help the Kirtland’s warbler would be extinct by now. The people of north central Michigan are understandably proud of their work to save the bird and happy to share their rare gem with visitors. There’s a Kirtland’s roadside marker in Grayling and a monument to the warbler in Mio. Read more about local efforts in this article from Michigan Live.

When not in Michigan, Kirtland’s warblers winter in the Bahamas, then migrate north through Florida and Ohio. During migration solo birds are sometimes found in Ohio in early May. This one, photographed by Brian Wulker, was in Stubbs Park near Dayton on 6 May 2016.

I can tell you there are plenty of insects for birds to eat in north central Michigan’s woods. The mosquitoes are frightful!!

UPDATE: yes we saw the Kirtland’s warbler. It’s amazing how loud his voice is, even when he sings with his back to us.

Graceful

We use words like powerful, strong or fierce to describe raptors but this one is different. The swallow-tailed kite (Elanoides forficatus) is truly graceful.

Named for their beautiful black tails, their flight is so buoyant that they barely flap as they swoop and turn to grab food from the air or the treetops. They seem to be moving in slow motion and it’s true. They can fly slowly because their wings and tails are so long.

Swallow-tailed kites live year round in South America but only visit the southern U.S. and Central America to breed. They eat mostly insects which they capture with their feet but supplement their diet with frogs, lizards and nestling birds during the nesting season.

I’ve seen solo kites returning to Florida in late February but my best experience was last month on the Road Scholar birding trip to Costa Rica. We saw flocks of swallow-tailed kites and they were spectacular!

At a pond near the road to Agua Buena, three kites skimmed the water, drinking and bathing, as graceful as swallows. They flew so low that we could see the bluish sheen on their backs. Jon Goodwill photographed them in the flight.

Later we took a detour … and we were lucky. Our guide Roger Melendez saw a pair of kites building a nest. Bert Dudley zoomed his camera for this video of the female arranging the sticks. (You can hear us talking in the background.)

I would love to show you the beautiful flight of these graceful birds. This video of three man-made kites flown by Ray Bethell is the closest approximation.

Swallow-tailed kites are so graceful.

Not A Squirrel

March 7, 2017Mammals, TravelKate St. John

Central American agouti, in Panama (photo from Wikimedia Commons)

What rodent is as big as a groundhog, looks like a squirrel, and has long legs like a small dog?

The agouti (pronounced “a GOO tee”) lives in forests, nests in burrows, and eats fallen fruit and nuts. Eleven species in the genus Dasyprocta range from Mexico to South America and in the Caribbean. Four are endangered because of habitat loss and over hunting but the Central American agouti (Dasyprocta punctata), the species I saw in Costa Rica, seems to be doing fine.

Agoutis look like very large squirrels but their bony legs and extremely short hairless tails set them apart.

Like squirrels, they are diurnal but avoid humans because we hunt them. Where they feel safe, though, they’re almost tame. At Las Cruces Biological Station they’re protected so they stroll around the Wilson Botanical Garden and stop by the bird feeders every morning to glean the fruit knocked off the feeders.

This agouti was wary when I followed him at the garden to take his picture. I was amazed when he raised the greenish fur on his rump when I got too close. He lowered it when I stopped following him.

Despite their physical resemblance, agoutis aren’t even related to squirrels. Their nearest relatives are guinea pigs.

Tanagers True And False

When I visited Costa Rica this month I saw more tanagers than I’d ever seen before … but some of them weren’t really tanagers.

Tanagers (Thraupidae) are the second largest family of birds on earth but their membership is constantly in flux as DNA tests move birds in and out of the family every year. In the photo above, all three birds used to be Thraupidae but one of them moved out in 2012.

Thanks to photos from fellow travelers Bert Dudley and Jon Goodwill, and from our guide Roger Melendez, here are tanagers we saw in Costa Rica, both true and false.

True Tanagers whose names include the word tanager:

Blue gray tanager (Thraupis episcopus), seen everywhere on our Costa Rican trip.

Cherrie’s tanagers (Ramphocelus costaricensis) were plentiful at Las Cruces Biological Station. Here’s a male, in velvet black and orange with a blue-gray beak, perching next to a female.

The two palm tanagers (Thraupis palmarum) in front are photobombed by a red-legged honeycreeper (Cyanerpes cyaneus). The honeycreeper happens to be a tanager, too.

Speckled tanagers (Tangara guttata) are subtly gorgeous birds. These were at Las Cruces.

Silver-throated tanagers (Tangara icterocephala) are very common.

Silver-throated tanager (photo by Bert Dudley)

True Tanagers whose names don’t say “tanager”. These species are in the Tanager family but you’d never know it by their names.

The red-legged honeycreeper (Cyanerpes cyaneus), posing above with the palm tanagers, is in the Tanager family.
The green honeycreeper (Chlorophanes spiza), below, is too.

The scarlet-thighed dacnis (Dacnis venusta) has beautiful scarlet thighs. Too bad the leaves are hiding them.

The streaked saltator (Saltator striatipectus), with a beak like a grosbeak, is a tanager.

The slaty flowerpiercer (Diglossa plumbea) is a recent move (or about to move) into the Tanager family. Some websites still list him as a Sparrow/Bunting (Emberizidae). Notice his hooked beak for piercing flowers.

False Tanagers that are still called “tanagers.” These birds in the Piranga genus were moved to the Cardinal family (Cardinalidae).

Flame-colored tanager (Piranga bidentata), plentiful at Savegre.

Summer tanager (Piranga rubra). Another cardinal relative.

“False” Tanagers that used to be in the Tanager family, though “tanager” is not in their name.

The yellow-crowned euphonia (Euphonia luteicapilla), pictured at the top with two true tanagers, was in the Tanager family (Thraupidae) until 2012 when he became a Finch (Fringillidae). This didn’t affect the euphonia’s life but it scrambled our field guides.

As you can see, the Tanager family can change in a flash!

The Falcon’s Laugh

Laughing Falcon, Costa Rica (photo by Bert Dudley)

27 February 2017

On my trip to Costa Rica I wanted to see a laughing falcon. And then I wanted to hear it.

Laughing falcons (Herpetotheres cachinnans) are very vocal birds that live in Central and South America from Mexico to northern Argentina. They specialize in eating snakes — even poisonous ones — which they kill by biting off the heads. Ch’ol Maya legend says the birds can cure themselves of snake bites. And yet, the birds sound spooky.

At dusk laughing falcons raise their voices in advertisement calls or duets. They start with a gwa call, getting louder and louder, that usually morphs into two syllables: gwa co.

One evening before dinner at Las Cruces Biological Station, Bert Dudley filmed this laughing falcon warming up at dusk.

The two-syllable call gave the bird its common name, halcón guaco, but those calls don’t sound like laughing.

Here is his laugh:

“Laughing Falcon (Herpetotheres cachinnans)” from xeno-canto by Mario Trejo. XC771495

The falcon only laughs when he’s worried or upset.
