Purple Martins Sing

We don’t think of swallows as songbirds but indeed they do sing.  Our largest swallow, the purple martin (Progne subis), has a unique sound that carries far.  With practice, you can recognize their voices even when you can’t see them.

Purple martins nest communally so the best place to learn their song is near a purple martin colony.

As you approach you’ll hear them singing as they fly, a liquid gurgling warble with throaty chirps.  (This in-flight recording, Xeno Canto XC13689 by Chris Parrish, includes other bird songs in the background.)

 

In early summer near their nests, you’ll hear songs, creaky rattles and the sound of begging juveniles. (Purple martins vocalizing near their nest, including begging calls of young, from Xeno Canto XC139568 by Russ Wigh)

 

The throaty, gurgling chirps are unique to purple martins.  When you hear it overhead, look for a nearby colony and go see the swallows sing.

The Sound of a Water Drop

A water drop sounds like this  …

… but that noise was made by a bird. (named at the end of the recording: XC148304 by Gary Stiles.)

It’s my favorite bird sound from Panama, made by a black-bellied wren (Pheugopedius fasciatoventris).

In his preferred habitat the wren is hard to see.  Mostly black and brown, his white throat looks like a splash of sunlight from below.

But he’s easy to hear. When he really gets going he doesn’t sound like a water drop at all.  This long melodious song (xeno-canto XC15653) was recorded by Don Jones on Semaphore Hill Road, the road to Canopy Tower.

 

The “water drop” is just a tiny snatch of song.

Nothing Can Go Wrong

What happens when you put a very smart parrot in the room with a voice-activated virtual assistant?

The owners of an African grey parrot named Petra also own an Amazon Echo, the tall black cylinder that activates a blue light when it hears the word “Alexa.”  Say “Alexa” and the computer carries out your command.

Here are three short clips of Petra with Alexa.  Above, “All lights on.”

“Tell me a fact” …

… and “lights off.”

 

What will happen next?    Um … Nothing can go wrong.

 

See more of Petra and Alexa on the PetraGrey YouTube channel.    Read more about Alexa here.

Lonesome Doves

What is that hooting?  Is it an owl calling in the middle of the day?

In the spring, male mourning doves (Zenaida macroura) perch high, puff their throats and make the deepest loudest sound possible for a bird so small.   The first rising note is lost in the distance, but the last two or three low notes carry far.

Last week at Moraine State Park I was momentarily transfixed when I heard “Hoooo Hoooo” across the valley.   When I paused to listen I realized that the cadence didn’t match any local owl. Not the great horned owl.  Not the barred owl.  I heard only two notes but they were spaced like the mourning dove’s.

Listen as a mourning dove sings one rising note, then 3 or 2 low notes.  Imagine you can hear only the last two notes.  (Xeno-canto recording XC153652 by Paul Marvin at Moosehead NWR, Maine)

 

Now compare it to these two owls:

Here’s a mourning dove trying to attract a mate (YouTube video by jkontrab).

 

Don’t be fooled when you hear this Hoooo-ing sound.  It’s just a lonesome dove.

The Starling’s Wiry Song

When you hear a wiry bird sound in the city, chances are it’s a male European starling (Sturnus vulgaris) singing to claim territory and attract a mate.

In the spring male starlings perch up high with a long view in all directions.  Then they lift their beaks, puff out their throat feathers and sing.  “Notice me!” they say.

But it’s not a pleasant song.  It reminds me of the sound made by fast-forwarding an audio tape. (That’s how old I am.)

Listen to this recording from Norway,  Xeno-Canto #XC383674 by Terje Kolaas.  That ticking (at 0:20) and whirring static is a bird!

 

When starlings drop their mechanical sounds they sometimes mimic other birds, though with a wiry edge.  Here’s a songster in Italy, Xeno-Canto #XC394233 by Marco Dragonetti.

 

When you hear sounds like these, look up and you’ll find a starling.

Singing In The Rain

On Thursday afternoon, a flock of blue jays called and sang in the rain outside my window.  They were so musical that I recorded them.

In the clip below you can hear rain falling and some harsh “jeer” calls, but notice the musical “tweedle” songs. Those are blue jays (Cyanocitta cristata) performing the pumphandle call as they bob on the perch.  These are faint; turn up your speakers.

Blue jays “tweedle”in the rain, 22 Feb 2018, the Pumphandle call:

This call sometimes means there’s a mild threat nearby, but it’s usually heard in the spring while they’re claiming mates and territory.

After a while, the flock changed its tune.  Listen for the faint “djeep djeep” in this clip.

 

Weather didn’t dampen the blue jays’ spirits.  They felt like singing in the rain.

p.s. As of yesterday morning, February 24, I’ve heard the first robins singing in the dark.

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!”

Warned By A Feather

Birds use alarm calls to warn each other of danger but pigeons are generally silent.  What sound could a pigeon make to signal danger?  The crested pigeon (Ocyphaps lophotes) of Australia uses his 8th feather.

Crested pigeons make a whistling sound when they fly — a high note on the down stroke, a low note going up.  Researchers found out that the eighth primary feather is the source of the high note and that the speed of the low-high modulation provides the warning.

When a bird flaps slowly the whistle repeats slowly, so other pigeons decide the bird is not afraid.  When the sound repeats rapidly it sounds like the pigeon is fleeing, so the other birds do, too.

Watch the video or read about this discovery here in Science Magazine.

 

p.s.  Mourning doves (Zenaida macroura) make a similar whistling sound when they fly.  I wonder if it functions as a warning sound.

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.
