Danger From The Air!

I'm sure you've seen starlings fly away to avoid a predator.  Have you heard their warning signal?

Over the years I've noticed that European starlings (Sturnus vulgaris) make a spitting sound just before they flee.  Sometimes only one or two birds call the alarm, a sharp note repeated three or more times.  It sounds like this.

When I look for the reason they're making the sound, I always see a hawk in the air.  I've learned to look for a raptor when I hear that sound.

The starlings must be saying, "Danger From The Air!"

Singing In November

This fall migrating mockingbirds came back to town to spend the winter.

Northern mockingbirds (Mimus polyglottos) were a southern species that now nest as far north as southern Canada. In autumn the birds move south and some decide that Pittsburgh is as far as they need to go.  New arrivals immediately set up territory and warn off other mockingbirds by singing, "Mine, Mine, Mine."

The songs are pretty, and pretty confusing because mockingbirds mimic other species.  For instance, this Xeno Canto recording by Joshua Stevenson has an American robin sound at 0:11.  No it's not a robin.

When I walk around my neighborhood this month I hear 15 different songs but they come from only two locations.  Two mockingbirds are "dueling" from opposite sides of Magee Field, the only birds singing in November.

Read how mockingbirds create The Voice of a Crowd in this vintage article from 2010.

Not A Sparrow, Not A Thrush

Not a sparrow, not a thrush, he's on his way to Georgia ... sort of.

American pipits (Anthus rubescens) nest in alpine and arctic tundra and winter in open country from the southern U.S. (including Georgia) to Guatemala.  Right now they're on the move through western Pennsylvania, but because our area lacks tundra the best place to find pipits is on mudflats.  And where are those?

Last Sunday a bunch of us stopped at Somerset "Not a Lake" in Somerset, PA to look for birds.  The lake was drained to repair the dam and out on the mud roamed killdeer, dunlin and other shorebirds.  Among them were two songbirds that pecked the mud, darted, zigzagged, ran and jumped. American pipits.

We could hear them, too.  Here's a loud pipit (with a soft longspur in the background):

On Throw Back Thursday this vintage article that lists why pipits aren't thrushes.  Back in 2010 it was posed as a quiz, but I've already told you the answer  😉    Quiz: Not A Thrush.

The Wax Eaters Are Back In Town

After most warblers have left for the winter, the yellow-rumped warblers come back to town.

Breeding across Canada and the northern U.S., yellow-rumped warblers (Setophaga coronata) spend the winter in North America as close to us as Ohio and eastern Pennsylvania, though not usually in our area.  In late fall they stop by in Pittsburgh.

Yellow-rumps don't have to leave for Central or South America because they have a unique talent. Their bodies can digest wax.  In winter they eat the waxy fruits of bayberry and juniper.  Since bayberry is also called wax myrtle, it gave our common subspecies its name:  the myrtle warbler.

On Throw Back Thursday, learn how yellow-rumped warblers get nutrition from wax in this vintage article:  Anatomy: Wax Eaters.

 

p.s. Notice that the warbler in the Wax Eaters article is wearing bright breeding plumage in black, white and yellow . Autumn yellow-rumps are dull brown with a faint vest and a broken white eye ring. The best clue to their identity is their yellow rump.

Makes You Happy

Growing up in Switzerland Melanie Barboni had a dream:  She wanted to see a hummingbird.  When she arrived at UCLA three years ago as an Assistant Researcher in Earth, Planetary and Space Sciences, she placed a hummingbird feeder outside her office window. She now hosts more than 200 of these tiny jewels every day.

Melanie's relationship with the hummingbirds has grown so much that she now recognizes about 50 individuals and has given them names. And though her research involves volcanoes and rocks, her nickname is the "hummingbird whisperer."

Why watch hummingbirds?

As Melanie says, "I mean, look at them. It just makes you happy!"

Read the full story here on UCLA's website.

Tiny Bathing Beauties

 

In August the hummingbird population is at its peak as adults and this year's juveniles prepare to migrate.  Searching for nectar, they visit flowers and backyard feeders.  They're also attracted to shallow, running water.

Here are two soothing videos of hummingbirds bathing.

Neither one describes where it's located and that presents a challenge ...

Can you identify these tiny bathing beauties?

Eaten By A Fish!

We've all seen fish jump to catch flying insects above the water but African tigerfish do much more than that.

Back in 2011, scientists conducting a telemetry study of barn swallows (Hirundo rustica) in South Africa were surprised to find that their subjects were being eaten by fish!

African tigerfish (Hydrocynus vittatus) are aggressive animals up to 3.5 feet long with very sharp teeth.  During the study at Schroda Dam, the fish jumped out of the water and ate low-flying birds.  In 15 days they ate 300 barn swallows!

In 2014 scientists used high definition video to record the fish in action. Click here to see.

 

Fortunately, there's someone on hand to eat the tigerfish.

Watch out, barn swallows!  Don't fly too low!

Scarlet Baby

On Tuesday I heard a sound in Schenley Park that I didn't recognize: a melodious call from a baby bird.

I found the bird flutter-climbing from a low perch to a high spot in a tree, moving fast and begging the entire time.  He had downy tufts on his head, a striped chest, big feet, short wings and an almost non-existent tail.  He looked a lot like the bird pictured above.

I couldn't identify the fledgling so I waited for his mother to bring food and she solved the mystery.  A bird just like her is pictured below (from Wikimedia Commons).

If you don't recognize her, here's another clue.  The father bird looks like this.  (I didn't see him that day.)

Obviously scarlet tanagers change a lot as they grow into breeding adults.  Read more about them in this vintage article from July 2008:
