Chicken In The Sky

Stellar nursery IC 2944 as seen by ESO's Very Large Telescope (photo by ESO)

If our eyes could look deep into space we’d see the clouds in this stellar nursery in the Centaurus constellation, 6,500 light years away.

This pink glowing nebula and clouds of dust were photographed by the European Southern Observatory (ESO) at Cerro Paranal, Chile.  The nebula’s formal name is IC 2944.  Because it’s visible to the naked eye it has a nickname too: The Running Chicken Nebula.

According to ESO’s description, the clouds are Thackeray globules “under fierce bombardment from the ultraviolet radiation from nearby hot young stars.”

Click here or on the image to find out what will happen to the clouds.

If you know where to look on a clear night, you can see a running chicken in the sky.

Another Kind Of Siskin

Published by under Beyond Bounds

While we listen and watch for pine siskins in Pennsylvania, here’s one of their cousins from the other side of the world.

This male Eurasian siskin (Carduelis spinus) resembles a pine siskin but his colors are more striking with his black cap and bright yellow and black wings and tail.  He lives in northern Europe and northeastern Asia and irrupts southward in some winters, just like our siskins do.  (Click here to see North America’s pine siskin for comparison.)

Without knowing his identity you could probably guess “siskin” if you saw him in Taiwan where he was photographed by K.Lin (a.k.a. Hiyashi Haka).

Please click on the image to see the original photo and scroll down to read K.Lin’s description of this bird.

Rarely Stands Still

Published by under Beyond Bounds

Silver-eared Mesia (Leiothrix argentauris), Mae Wong National Park, Nakhon Sawan,Thailand (photo by JJ Harrison via Wikimedia Commons)

Except for the “jumpy” attitude in her eye, this beautiful bird looks as if she forages slowly on the ground.

Silver-eared mesias (Leiothrix argentauris) are native to Southeast Asia where they live in the forest eating insects and fruit.

DNA testing recently re-classed them into new family (Leiothrichidae) and genus names (Leiothrix instead of Mesia), so it’s confusing when you look them up.  The books are hopelessly out of date and the Internet has both names.

At this link to an old name, Mesia argentauris, you’ll find videos, photos and sounds.  The birds are so fast-moving that some of the videos are posted in slow motion!  Even when standing still, silver-eared mesias rapidly flick their wings and tails.  Click here to see a male foraging at a feeding station.  Wow!

This female was photographed in Mae Wong National Park in Nakhon Sawan, Thailand.  After you’ve seen them move, you realize how hard it was to capture this sharp photo.

Shorebird Of The Savannah

Published by under Beyond Bounds

Spotted thick-knee, South Africa (photo by Cris Hamilton)

He looks like a shorebird, doesn’t he?  But you won’t find him in North America.

This is a spotted or Cape thick-knee (Burhinus capensis), a nocturnal(!) bird who lives in the tall grass of the African savannah.

Cris Hamilton photographed this one in the Serengeti in eastern Africa.

If you don’t want to travel that far you can see him at the National Aviary.

Ugly But Beautiful

Published by under Beyond Bounds

From a distance the king vulture (Sarcoramphus papa) of Central and South America looks simply black and white but up close his naked head is amazing.

That’s his skin that’s so colorful — yellow, orange, red, blue, gray and purple.

Ugly but beautiful.

Click On Every Penguin

Penguin Watch: count the penguins (image from Zooniverse Penguin Watch)

Are you hooked on penguins? Would you like to see more of them from the comfort of your home?

Check out the new online citizen science project, Penguin Watch, where you can view more than 175,000 photos of Antarctic penguins, chicks and eggs.

Because penguins are declining, scientists are monitoring them using remote cameras.  The cameras have taken a lot of pictures — so many that the task of counting the penguins and their breeding success is impossible for the few scientists involved.  That’s where citizen science comes in.

Zooniverse put the photos online and made an easy tool for counting the penguins.  Look at the photo.  Click on every penguin. Done!  The clicks become a crowd-sourced map of Antarctica’s penguins.

It doesn’t matter if you make mistakes because crowd-sourcing smooths out the errors. You can even chat about the images with other volunteers and the researchers at Penguin Watch Talk.

Help scientists understand why penguin populations are declining and how to protect them by visiting www.penguinwatch.org or these links on Facebook and Twitter.

Look at the photos.  Click on every penguin.  That’s all you have to do.

Gallinule On Steroids

Purple swamp Hen at Wollongong botanic gardens (photo by Toby Hudson)

Have you ever seen this bird?

It resembles a purple gallinule (Porphyrio martinicus) but it’s the size of a chicken with darker plumage and scary-looking feet.  It looks like a gallinule on steroids.

This is, in fact, a purple swamphen (Porphyrio porphyrio), native to Africa, tropical Asia, Indonesia, Australia and New Zealand, but you don’t have to travel that far to see one.

I learned in an ABA article by Bill Pranty that purple swamphens mysteriously appeared at the Silverlakes development in Pembroke Pines, Florida in 1996.  Some speculated that the birds had escaped from Miami MetroZoo during Hurricane Andrew four years earlier, but the zoo hadn’t lost any swamphens.  Closer inspection revealed that two breeders a quarter mile from Silverlakes had allowed their purple swamphens to roam free.  Naturally some of the swamphens didn’t come home.

By October 2006 purple swamphens were so prolific that Florida’s wildlife managers decided to eradicate them, but more than two years of shooting had no effect.  The swamphens continued to expand their range.  The failed eradication program ended in December 2008.

The first time I ever saw a purple swamphen was last December at Green Cay Wetlands in Boynton Beach, Florida, about 40 air-miles from their original release point.  I’ve birded in Palm Beach County numerous times since the swamphen’s release — especially at Wakodahatchee Wetlands where they appeared in 2000 — but it took 20 years for me to see one.

Though the bird was added to the official ABA Checklist in February 2013, their reputation is tarnished.  When I pointed out my new Life Bird to another birder standing nearby she said, “They aren’t a good thing to see.”

Read about the purple swamphen’s history, the unsuccessful attempt to eradicate them, and their expansion in Florida in this article by Bill Pranty.

Stunningly Blue

Published by under Beyond Bounds

Purple honeycreeper, Trinidad (photo by Greg Smith via Flickr, Creative Commons license)

Though he’s called a purple honeycreeper this bird looks stunningly blue in photographs.

Since deep purple can be misinterpreted as blue by the camera lens I wonder … Is this bird purple in real life?  I’d have to visit northern South America or Trinidad to verify his color.  He doesn’t migrate.

Click on his scientific name — Cyanerpes caeruleus — for his range map.

Storing Food

 

Fall’s here now. Winter’s coming.  Birds who stay through the winter are already using their best survival strategies.

Blue jays bury acorns, nuthatches hide seeds in bark crevices, but the real champion of food storage is a bird who doesn’t live in Pennsylvania.

Check out this Cornell Lab video from southern California.  I think California is a warm place where a bird couldn’t possibly need a large pantry but acorn woodpeckers never stop.

 

(video from Cornell Lab of Ornithology on YouTube)

p.s. Check the comments for the real reason why this California woodpecker stores so much food.  Thanks to Janet Campagna for her on-the-spot report.

A One Day Wonder

Red-necked phalarope at Conneaut Harbor (photo by Steve Gosser)

Pittsburgh birders always hope that a trip to Lake Erie’s shore will uncover a rarity.  Will there be something awesome at the end of that 2.5 hour drive?

This rare bird showed up at Conneaut, Ohio nine days ago.  The August 15 rare bird alert reported an immature red-necked phalarope (Phalaropus lobatus) on the sand spit.  Birders flocked to see him so far from his species’ normal migration routes west of the Mississippi and offshore in the Atlantic.

Steve Gosser photographed him less than 24 hours later.   Isn’t he gorgeous!

That was Saturday.  I drove to Conneaut on Sunday and the bird was gone.

I should be more nimble if I want to see these One Day Wonders.
