Soon, Very Soon

Published by under Crows, Ravens,Hiking


Last Sunday I hiked the Vondergreen Trail at Beaver Creek State Park near East Liverpool, Ohio. 

The trail follows Little Beaver Creek as it cuts through the surrounding hills.  Along the way there are remnants of the channel and locks of the Sandy and Beaver Canal that ran for 73 miles through 90 locks and two tunnels from Bolivar, Ohio to the Ohio River at Glasgow, Pennsylvania.

Completed in 1848, 20 years after it was chartered, the canal operated for only four years.  It closed in 1852 after the Cold Run Reservoir Dam broke and ruined much of the canal.  By then competition from the Cleveland and Pittsburgh Railroad made it uneconomical to rebuild.  The canal boom ended abruptly.

At Grey’s Lock I stopped to read the historic marker but I didn’t absorb what it said because my attention was snagged by the sound of crows.  Just out of sight, they were flying my way.  150 passed overhead and congregated somewhere on the north side of the creek, still within earshot. 

That flock is just the start of something big.

Right now the crows are gathering in the countryside.  150 here, 200 there.  Some have made it to town, but no great numbers yet.

Soon, very soon, the crows will come to Pittsburgh.  By winter we could have 10,000!

The Wake-up Crow

Published by under Crows, Ravens

Speaking of crows…

Today in Maine it’s light more than half an hour before sunrise but I don’t need a sun chart to tell me.  I know this because of the crows.

At the earliest light, the crows outside my window open their eyes and wonder if it’s time to get up.  They never think about this without asking their friends.

“Awk!”

I wake at the sound.  5:08am.  That inverted “Caw” must have meant “Are you there?” because a second crow answers, “Awk!”   Then a third bird,  “Awk!”  And a fourth, “Awk!”

Silence.  I doze off.

A few minutes later, “Caw!  Caw!”

Four crows leave their roost.

I’m wide awake.  Should I get up?  Isn’t this early rising excessive on vacation?

“Caw, Caw, Caw!”  “Caw, Caw, Caw!”

No point in trying to sleep!  There’s no “snooze” button on the Crow Alarm.

Do Tools Make You Smart?

Published by under Crows, Ravens

Fall is coming, school’s in session and in about eight weeks the crows will be back in town.

For now they’re in no rush to get to Pittsburgh. I don’t expect large numbers until October, but when they come will I see a difference in them?  Did they learn new tricks this summer?  Will they be even smarter than last year?

Perhaps they’ve learned to use tools!

Here’s a year-old video from Science Friday that shows just how smart crows can be.  (Click on the image to get to the video website from September 2010.)  The birds in the film are New Caledonian crows who live on a Pacific island and are famous for using tools.

Are they smart?

Watch and see.

(video from Science Friday)

p.s. Don’t worry when the video ends with a pop-up window asking if you’d like to use their tool(!) to embed it on your own website.  It’s a nice tool .. but you don’t have to use it.   ;)

Let’s Tumble!


Steve Valasek sent me this photo of a raven landing and said, “We visited Acoma Pueblo on Monday and saw many ravens riding the updrafts on the sides of the mesa.  Our guide said that he’s actually seen them fly upside down.”

You bet they fly upside down!

Ravens are very acrobatic fliers.  I’ve seen them tumble together many times as they launch over the cliffs at Acadia National Park in Maine.  They seem to get a lot of joy from doing this and might even be competing to see who can make the best moves.

It’s so hard to describe how cool they are that I found a video of ravens sky-tumbling at Lundy Island, Great Britain.  Watch carefully at 29, 40 and 44 seconds and you’ll see one of them completely flip over sideways.  Awesome!

.

Ravens are cool, but for speed you can’t beat a peregrine.  While searching for the first video, I found this one of a peregrine  harrassing two ravens at Culver Cliff, Isle of Wight.  The big soaring birds are ravens.  The very fast, smaller, flapping bird that appears from above at 3 seconds and 13 seconds is the peregrine.

Let’s tumble!

Almost Ready To Fly

Published by under Crows, Ravens

It’s not often that you see a raven’s nest in western Pennsylvania.

This spring Tim Vechter has been watching a family of ravens near Greensburg.   He took their picture through his scope last week when the four young birds were just about to fledge.  By now they’ve probably left the nest. 

I wish I could have been there to see them fly.

Ravens are so cool

No Crows…?

Published by under Crows, Ravens


It’s rare to notice an absence in nature.   Our brains are wired to see “This is here, this is new,” but unless we’re specifically watching for something, we don’t notice when it’s gone.

The crows are a case in point.

Last fall in the city of Pittsburgh everyone remarked that there were, “So many crows!”   “Too many crows!”  and even “The crows are awful!”

But look now.  Where are they?  Have you seen more than one or two lately?  Have you seen any?

They are virtually gone. 

We didn’t have to do anything to “get rid” of them.  Some of them left town to nest in the suburbs and those who stayed to nest here are extremely secretive.

This is the crows’ quiet period.  

If you don’t like crows, savor this moment.  When their young fledge they’ll be noisy again.  

This fall they’ll be back in the thousands and everyone will say, “There are so many crows!”

The Crows Know

Published by under Crows, Ravens


Saturday morning there was a mystery on my street.

Ten minutes before dawn a huge flock of crows flew over my neighborhood, then turned and wheeled over the ballfield, cawing loudly. 

They were hard to see in the dark but they were easy to hear.  They circled several times outside my window.  It was so unusual that I reported them on PABIRDS.

At mid-morning I heard sirens.  Six police cars, a firetruck and an ambulance roared up my street to the ballfield.  The firemen carried their medical emergency kits to the bleachers, an area not visible from my side of the park.  Soon they returned and drove away.   The ambulance stayed longer but he left too without doing anything. 

Meanwhile camera crews from all three TV news stations had set up their equipment across the ballfield and were pointing their cameras at the bleachers.  A plain white car arrived in front of my house and three people emerged, pulling on purple latex gloves.

By now I had guessed that someone was dead.  I couldn’t stand the suspense so I got my 10-power birding binoculars and walked around the ballfield to the vicinity of the TV crews. 

With binoculars I could see that there was indeed a body on the cement bleachers.  The police and detectives were taking pictures, checking the scene, examining, talking.  The body was on its back, upside down, crumpled over itself as if it had fallen from the sky.  It was in an unnatural position but its white face was up, easily seen from above in faint light.

So that’s why the crows wheeled and cawed. 

The crows know.  They saw it first.  Now it’s up to the coroner and detectives to find out what happened. 

p.s. Here and here are the news articles so far.

Crows at the Roost, Pittsburgh

Published by under Crows, Ravens


Sharon Leadbitter captured this video of thousands of crows about to roost near 21st Street in the Strip District this evening, December 9.

There’s nothing like thousands of birds to get the heart started.  Thank you, Sharon for sending this along!

Eating Crow

Published by under Crows, Ravens


If I was to place a bet on crows I’d wager they didn’t spend last night in the plane trees on University Place in Oakland.  I’d win this bet because of what I found there less than 24 hours ago.

Yesterday morning I got a call from a Pitt employee who tracked me down out of concern for the peregrines.  Marian had found a very large raptor standing on the ground near Soldiers and Sailors Hall on University Place.  The bird would not fly away and there were feathers scattered on the ground beneath its feet.  She was concerned that this was one of the peregrines and that it was injured and unable to fly away.

The situation sounded like a red-tailed hawk on a kill but you never know.  I was happy to help and went over to check.

As I arrived at University Place I noticed a lot of crow poop on the sidewalk beneath the London plane trees.  The closer I got to the site, the more poop there was. 

When I reached the place Marian described I didn’t find a large bird on the ground but I could tell exactly where he’d been.  Right next to the sidewalk was a big pile of crow feathers, a few crow bones and a crow’s skull and beak.  Whoa!  Someone had been eating crow!

I imagined the fear in the flock when that raptor arrived.  I’m sure it scared the poop out of them and they left in a hurry.  No wonder the sidewalk was gross.

Now there’s one less crow among the 10,000+ who roost in Pittsburgh and those still living can see how he died. 

I can pretty much guarantee the crows won’t be back there soon.

A Crow in Jay’s Clothing?


To those of us in eastern North America this bird looks all mixed up. 

He has a crow head, blue jay colors and an incredibly long tail.  He resembles crows and jays because he’s a corvid.  We don’t see him in Pennsylvania because he lives west of Iowa and east of the Sierra Nevadas.  Say hello to the black-billed magpie.

I saw this bird once.  But now I have never seen him.  Years ago I saw a magpie outside my airplane window as we taxied to the gate at Charles de Gaulle airport.  Then, in their never-ending quest to reclassify birds the American Ornithological Union split the black-billed magpie from the European magpie and this bird dropped off my life list.   He is now Pica hudsonia.  The bird I saw in Paris was a Pica pica.

If I visited open country in the western U.S. I could easily re-add this bird to my list.  Black-billed magpies are loud and conspicuous, midway in size between blue jays and American crows.  Like crows they are smart, omnivorous and versatile.  Their claim to fame is their very long tail (more than half their body length) and their huge ball-shaped stick nests.

Maybe I should fly to Denver and look out the airplane window.  ;)
