Mud Season

In this weirdly warm winter all the snow melted a week ago, the daffodil leaves poked out further, and we didn’t have to wear jackets.  At 61o on January 31 it was 26 degrees above normal!

Though yesterday’s temperature was exactly on target, today will be 8 degrees above average.  That’s not a huge difference but enough to maintain our early mud season.

We already had mud in our neighborhood ballpark when rain on Wednesday morning enhanced the creamy mudscape.

Off the beaten path at Schenley Park it was muddy too, though navigable.

Are the plants in your area waking up early?  Put on your mud boots and go out to see.

The Reddish Egret’s Water Ballet

February is the month when birds are at a low ebb in Pittsburgh and birders want to get out of town.  Many of us think of Florida.

Whether or not you’re heading south you’ll enjoy this video of heron life at Ding Darling National Wildlife Refuge.  Filmed and narrated by Jo Alwood, it shows the reddish egret at his best — dancing his water ballet.

Birds’ Body Language

On Throw Back Thursday, I found this gem in the archives from 2009.

What do birds mean when they puff up or raise their head feathers?  Imagine if we used the same signals.

Pitt Peregrine Highlights, 2015

Looking back, 2015 was an emotional roller coaster for Cathedral of Learning peregrine fans.  It began at a low ebb with Dorothy showing her age and ended with Hope for the future.

As promised, here’s the long awaited slideshow of Pitt Peregrine Highlights, 2015 with a summary below:

*NOTE:  A healthy chick normally doesn’t fall on his back and if he does he’s able to right himself quickly.  In reviewing the snapshots for this slideshow I discovered that Dorothy had been flipping the chick for weeks. She was so quick we hadn’t noticed.

Drinking Blood?

When I wrote that yellow-headed caracaras pick ticks off of mammals Dr. Tony Bledsoe pointed out that, based on the similar behavior of an African bird, it’s possible the caracaras are also drinking the animals’ blood.

Ewww!  What gives?

In Africa, there are birds called oxpeckers (two species in genus Buphagus: yellow-billed and red-billed) that also perch on mammals and eat ticks, lice, fleas, and biting flies found on the animals’ skin.  Studies have shown that individual oxpeckers eat up to 100 engorged ticks or 13,000 nymphs per day.  Quite a benefit to the animal!

Engorged ticks contain tiny blood meals so it’s not a big leap that the oxpeckers sometimes to go directly to the blood source, pecking and plucking at an animal’s wounds.  Despite this parasitic and perhaps painful behavior, many mammals tolerate the oxpeckers although elephants and some antelopes shoo them off when they land.

Yellow-headed caracaras are unrelated to oxpeckers but their tick-eating behavior extends to blood meals as well. The Handbook of the Birds of the World includes this remark about the caracara’s eating habits:

“Perches on cattle and Capybaras (Hydrochoerus hydrochaeris) to pick off ticks; picks flesh from open wounds on backs of cattle, which often seem oddly indifferent to the process.”

It sounds gruesome but the benefits of having your own portable tick-remover apparently outweigh the occasional blood meal.

Get Ready For Groundhog Day!

Published by under Books & Events,Mammals

Get ready for Groundhog Day!

Tomorrow is the mid-point of winter, halfway between the winter solstice and the vernal equinox.  February 2 is also the day when a very special rodent, Punxsutawney Phil, emerges from his den to predict the weather for the next six weeks.

Phil never makes his prediction in isolation.  His day in the sun (or shade) spawns a huge celebration in Punxsutawney, PA.  Preview the excitement in his eight minute promo video above.

If you don’t like winter, then hope for an overcast sky so that Phil has a day in the shade.  Here’s why.

Near Open Water

Often the best birds are near open water, even if they don’t eat fish.

Anthony Bruno found these two at Loyalhanna Dam on January 27 and 28 — an eastern screech-owl (who doesn’t eat fish) and an immature bald eagle (who does).

As we head into February, birds are harder to find in western Pennsylvania.  It’s the low ebb of our birding year.

Check out the places with open water and you’ll have better luck.

Look closely.  They may be camouflaged.

p.s. I went to Loyalhanna Dam today and saw 5 bald eagles but I missed the eastern screech-owl.

Not A Bluebird

Published by under Beyond Bounds

The bluest bird. Only a subspecies? (photo from Wikimedia Commons)

The bluest bird. But only a subspecies? (photo from Wikimedia Commons)

This is a blue bird but he’s not a bluebird.

He used to be in the thrush family, just like our eastern bluebirds, but he’s been reclassed as an Old World flycatcher (Muscicapidae).

He is from the Old World.  He breeds in the Himalayas at 9,800-14,500 ft and migrates downhill to spend the winter at 4,900-8,200 ft.  This particular bird was photographed in winter in the mountains of Thailand.

But who is he?

When the photo was taken he was called a Himalayan bluetail (Tarsiger rufilatus) but his species distinction is up in the air. Though he’s a short-distance migrant and much bluer, he’s under consideration as a subspecies of the orange-flanked bush-robin (Tarsiger cyanurus).  For now his old exotic name has disappeared.

He’s not a bluebird.  He’s not even a Himalayan bluetail.

How To Raid A Wasps’ Nest

There’s a bird of prey in South America that likes to raid wasp nests to eat the larvae.  The problem is that red-throated caracaras (Ibycter americanus) have bare skin on their faces and throats, an easy target for stinging wasps.

How do the birds get the larvae without a lot of pain?  Do they chemically repel the wasps?

In 2013, Canadian Sean McCann and colleagues studied red-throated caracaras in French Guiana on the north coast of South America.  They learned that, no, the birds don’t repel the wasps.  The caracaras are attacked but they compensate in other ways.

Watch the video to see how the birds nab their tasty meal.  They know something about wasp behavior that we had been ignoring.

Click here to read more in their PLOS ONE paper, Strike Fast, Strike Hard, or here at ibycter.com.
