As if dressed in its finest clothes, this Eurasian spoonbill steps through the marsh and scans the water with its bill — but it doesn’t soil its feathers.

In fact these are its finest clothes.  It’s in breeding plumage.

How elegant.

Walks On Water

12 August 2011

What a cute baby bird … but look at those feet!   Each toe is as long as his tiny body.

This is an African jacana chick and his lifestyle is as odd as his feet.

He hatched in a floating nest built by his father on a shallow tropical lake.  Not only did his dad build the nest but he incubated the eggs and raised the chicks.  

His mother had nothing to do with the family.  After she laid the eggs she went off to spend time with the other males in her harem as is typical in the jacanas’ female-dominated society.

Dad’s nest building skills were acceptable but a floating nest does get wet.  Fortunately the eggs are waterproof and the chicks precocial — they can walk and find food as soon as they hatch.

And that leads back to this baby’s feet.

Since jacanas live on lakes they have to be able to walk across very flimsy floating vegetation.  Their big feet can do this because they act like snowshoes, distributing the birds’ weight across a wide surface.   This earned African jacanas the nickname “lily trotter.”

If Only…

There are many kinds of starlings but not in the western hemisphere.  The only kind we have is the European starling, introduced in New York’s Central Park in 1890

Unfortunately they’ve given starlings a bad name.  They spread across the continent in less than 100 years, displaced native cavity-nesting birds, and now boast a population of 200 million.  They’re ubiquitous in cities, noisy, and oily-looking.  There’s not much to love about a starling…

…unless it looked like this!

This is Hildebrandt’s starling (Lamprotornis hildebrandti), a native of Kenya and Tanzania.  Like our starlings it lives in relatively open areas and nests in cavities.  The male and female look alike and the young are dull brown. 

If only our starlings looked like this, perhaps we’d like them better.

City in a Tree

Last week when I wrote about the Avian Architecture book, Sharon Leadbitter commented on two amazing nests she’d seen on the web.  Here’s one of them.

Sociable weavers (Philetairus socius) are sparrow-sized birds who live in the Kalahari desert in Namibia, Botswana and South Africa.

Unlike most birds who build a nest for their own babies and then abandon it when the young have flown, sociable weavers build a permanent structure that functions as a communal nest and roost.  It’s the size of a small car, the largest nest found anywhere, and can house up to 100 pairs of birds, their children and grandchildren.

The top of the nest is basically flat while the underside, shown above, is dotted with entries to the chambers.  The weavers build it entirely of straws which they shove into the structure.  This BBC video by David Attenborough shows how the weavers do it.

Sociable weavers are such good builders that other species, such as the pygmy falcon, nest in the empty chambers while the weavers live there.

It’s an amazing feat for a small bird. They’ve built a city in a tree.

Happy To See You

These rare James’s flamingos live in the Andes mountains of South America.

Though only three feet tall, their colors are stunning with pale pink bodies, yellow beaks, black wingtips, and bright carmine accents on their necks and backs.  They look as if they were painted.

Until I found this photograph on Wikimedia Commons, I had no idea these birds existed.  They’re so beautiful I had to share them.

I’m sure we should all be as happy as kings.”

Quiz: Be a Bird Sleuth


Today’s blog is an opportunity to improve your bird identification skills and it’s a challenge.

What bird is this?

To level the playing field, I’ve picked a bird I’ve never seen.

Let’s go through the normal identification clues in order of importance.  These are the questions I ask myself when birding.  Many of them will help here.  (Yes, the order of the clues really matters.)

  1. Where on earth is this bird?  Out-of-place birds are rare.  Narrow the possibilities by knowing which birds occur where you’re birding. 
  2. What habitat is the bird in?  Even on migration birds pick their preferred habitat if at all available.  Is the bird at the ocean?  a lake?  river? streamside? dense woods? open woods?  pines? oaks? a field? a swamp? a mudflat?
  3. What sound does it make?  If you can identify birds by song, this is useful in Spring through June.  (If you can identify call notes you’re such an expert that you know what bird this is.)
  4. What size is it?  The size of a goose?  Larger?  The size of a crow?  robin?  sparrow?  Smaller than a sparrow?
  5. What shape is it?  This is really important!  Check its beak:  long?  short?  thick?  thin?  big and fat?  thin and short?   Check its legs:  long? short? almost non-existent?  Check its neck: long? short? very short?  Check its tail:  long? short? fancy?  Does it have ear tufts?  Does it have a crest?
  6. What is it doing?  How does it perch?  (Does it perch at all?)  How does it fly?  (short bursts, darting, hovering, soaring)  What does it eat? Food is a major clue.
  7. What color is it?  Color is actually the last clue though our brains lock onto it first.  You can actually identify a bird in the field without knowing its color.  How many of you can identify a crow by hearing it caw? …and you don’t even need to see it!

.

Here are the clues applied to the bird in this picture.  In some cases I’ll tell you more than you could know from a random photo.

  1. Where on earth is this bird?  It was photographed in Brazil.
  2. What habitat is the bird in?  It’s perched on a branch without lots of leaves.  Wild guess: This bird is in open woods.
  3. What sound does it make?  We can’t tell in a photo.
  4. What size is it?  We can barely tell in a photo so I’ll have to say:  This bird is the size of a starling.
  5. What shape is it?  Great question!   
    • Look at that beak: long and thick and significantly large compared to its body length. 
    • Notice the whiskers.  Most birds with whiskers catch insects in flight — nighthawks and flycatchers, for instance.  If this bird resembles another whiskered bird, it could be a relative? 
    • Check its legs:  short.
    • Check its neck:  short.
    • Check its tail:  long!  about 1/3 of the bird’s length
  6. What is it doing? 
    • How does it perch?  It typically perches with its beak tilted up.  Its stance is like a hummingbird except that its beak and body are too large.
    • How does it fly?  We can’t tell in this photo.
    • What does it eat?  Whiskers indicate that it probably eats flying insects.
  7. What color is it?  Rufous and iridescent green.

So…

This bird has a beak like a woodpecker (a distant relative) but its whiskers indicate it eats flying insects.  Those who have seen this bird in the wild have called it “a glittering hummingbird the size of a starling.”

Best Bird in Smithfield


Today I’m back from a four-day weekend with my family in Smithfield, Virginia. 

While there I took long walks in Windsor Castle Park, a beautiful park with new boardwalks easily accessible from the historic downtown. 

The park has a variety of good habitat for birding: woodlands, fields and saltmarsh.    At low tide thousands of small crabs crawl the muddy banks of the saltmarsh, looking for food and becoming food themselves.  There’s a heron rookery near the Cypress Creek overlook where the “baby” herons are now nearly as tall as their parents and quite loud when they’re hungry.  I bet they eat crab for dinner.

I was happy to see many species that I never see in Pittsburgh including laughing gulls, royal terns and black vultures but the best birds by far were the summer tanagers.

The summer tanager (Piranga rubra) is a bird of southern forests.  They do nest in the southwestern corner of Pennsylvania but you have to go out of your way to find them.  At Smithfield I could hear them singing and a pair even came down to see me!

The male is all red and the female all yellow-green.  They have larger, longer beaks than scarlet tanagers and their head feathers stand up a little, giving them a Jimmy Durante look.  (Their back feathers don’t stand up. The bird in this photo has a feather out of place.)

They’re famous for eating bees and wasps and will even take the grubs out of wasp nests.  (Brave!)   They winter in Central and South America where they eat fruit as well.

Looking For Cars


Early this month I spent six days in Nevada and never saw a roadrunner.  It was the one disappointment of my trip.

To compensate, Steve Valasek sent me photos of the roadrunners near his home in New Mexico. 

What does a roadrunner do before he crosses the road?  He looks for cars.  😉

Best Bird


Fifteen years ago I learned about Best Bird from Chuck Tague when I took his Spring Warblers class at Presque Isle State Park.

As the class wrapped up two intensive days of birding Chuck asked each of us, “What was your best bird?”  Mine was a least bittern, a life bird(*) who flushed from the reeds when I stepped alone to the edge of the marsh.

Best Bird is now a tradition with me.  At the end of every outing I think back on the birds I’ve seen and their behavior.  Who was most beautiful?  Who did the most interesting thing?  Which bird took my breath away?  I enjoy thinking back on the birds that made the outing worthwhile.

My trip to Nevada was so full birds that it’s hard to pick the best.  I saw 127 species, nine life birds and thousands of individuals.  Rather than pick a single Best Bird, here are some of the many “bests” of my trip:

  • On my first day, in my first hour of birding I saw a peregrine falcon hunting the ducks at Henderson Bird Preserve.
  • There were two beautiful “gray ghost” northern harriers at Duck Creek Wetlands last Saturday.  I was glad to be watching them in 75 degree weather on the east side of the valley.  Through my binoculars I could see it snowing in the west.
  • At Corn Creek I saw a Swainson’s hawk (another life bird) when a raven hassled it until it flew away.
  • Most unusual was a group of great blue herons and great egrets roosting on an unfinished roof near Floyd Lamb Park.  The home’s roof was tar papered and stacked with ceramic tiles, waiting for the roofers to begin.  The herons and egrets perched among the tiles.  I would never have seen them but one of the herons perched on the crest and I saw his silhouette.
  • On Sunday at Corn Creek there were phainopeplas perched on every available high spot.  They like the place because there is so much desert mistletoe there.
  • Thanks to a helpful local birder, I saw a vermilion flycatcher for the first time in my life.  It was at Corn Creek, a beautiful male bird like the one pictured above.  There was even a Pittsburgh connection: the birder who showed me the vermilion flycatcher grew up in McKees Rocks.
  • Amazingly, I saw more ravens than crows.  Crows are uncommon in the desert.

(*) A life bird is a species seen for the first time in my life.

Graceful Black and White

My two favorite species at Henderson Bird Preserve are American avocets and black-necked stilts.   Both are long-legged wading birds with delicate bills but the stilts’ bodies are so small and their legs so long that they look fragile.

When I visit Henderson in April the avocets and stilts have arrived from their wintering grounds and they’re courting.  They fly by, ignoring me, so intent on their social interactions that I’m able to get quite close.

This video from Cornell Lab of Ornithology gives you an idea of what it’s like to be at the Bird Preserve on an April morning (though I’ve never encountered a flock as large as shown here).  It perfectly captures the beauty and grace of the black-necked stilts.

I’m glad I came to Nevada to see them.  And now I’m coming home.
