About once a week I look back seven years to highlight an old blog post that is still interesting today. This morning when I looked back, I was stunned at how different spring is now in southwestern PA compared to April 2014. A lot has changed in seven years. Migrating ducks, singing frogs and flowers are showing up earlier in 2021. For instance …
Have you seen a lot of ruddy ducks lately? Seven years ago the bulk of their migration through Moraine State Park began on 5 April 2014. This year it started almost a month earlier on 11 March 2021 and is basically over now. Here’s the 2014 blog post that caught my attention: Ruddy Bubbles. Click on the hotspot icons here to see this year’s ruddy duck activity at Moraine.
Have you heard spring peepers or wood frogs calling lately? Seven years ago they were loud on 6 April 2014 (Jeepers Creepers) but this year their peak was on 12 March 2021 at Racooon Wildflower Reserve: Sights and Sounds of Early Spring. When I returned to Raccoon twelve days later the frogs were quieter. They were silent on 4 April 2021.
Grackle Day is coming this week. For some it’s already here.
The arrival of migrating blackbirds and grackles is one of the earliest signs of spring. Common grackles (Quiscalus quiscula) leave the East End of Pittsburgh during fall migration and don’t return until early March, usually around the 5th. I haven’t seen a grackle yet but I found a red-winged blackbird — just one — in Schenley Park on Friday 26 Feb, my First of Year.
Friends in Beaver County reported small flocks of grackles at their feeders on Saturday 27 February. I’m disappointed the birds bypassed Pittsburgh but am keeping my eyes open for their arrival here.
Sometimes I hear their “chucking” sound before I see them. Listen for …
Then they point their bills up, strut and puff and “skriiNNNK.”
I can hardly wait!
Will this be Grackle Day?

Goose barnacles often attach themselves to old wood and float from tropical seas to northern shores including the shores of Britain. The barnacles pictured here and in the video below are Lepas anatifera. Their bodies are supported by a long, flexible stalk (a peduncle) that resembles a goose neck.
These fascinating crustaceans are goose barnacles. They live in unmistakably dense colonies, often attaching themselves to marine objects. They occasionally get washed up around our shores. ??
Nowadays that story sounds silly but we shouldn’t be too smug. We still create stories to explain things we don’t understand and spread them quickly on the Internet. In the future our fantastical stories will sound silly, too. I can think of a few about the coronavirus.

If you want to see a rare gull that breeds in Europe or the arctic, February is the best time in Pittsburgh.
Gulls need open water for food and shelter so when ice forms they have to leave. Arctic breeders move to openings in the sea ice (polynyas) or fly south along the coasts or to the Great Lakes. When it’s very cold the Great Lakes freeze by February and the gulls move further south. That’s when they find Pittsburgh.
Though our city is 300 miles from the ocean a few gulls stay here year round. Several dozen herring gulls (Larus argentatus) breed on our rivers and a few non-breeding ring-billed gulls (Larus delawarensis) spend the summer. In winter they are joined by hundreds more.
According to the Great Lakes Total Ice Coverage Map from 30 Jan 2021, the Toledo end of Lake Erie is fully iced up and it’s pretty thick now at Cleveland. If he was staying near Cleveland he would have to leave.
Last week was too overcast for a good photo but Steve Gosser returned yesterday for these stunning pictures.
Then on Saturday 9 January 2021 the birds were even closer to home. Matt Juskowitch found a dozen redpolls at Bethel Green in Allegheny County. Here’s Matt’s documentation shot, proving that the birds are real. Notice the red hat! Adult male redpolls also have a pink wash on their chests.
I went to Bethel Green yesterday, 10 Jan 2021, and saw 9 redpolls eating birch catkins. Here’s one of Matt’s photos from his eBird report yesterday afternoon.
The birds are moving around from place to place so they may show up at your own birches, alders, sunflowers or feeders. Watch for small finches with red on top of their heads (“poll” means head). They are only as big as goldfinches.
When red knots come to the UK in autumn they gather in flocks much larger than I have ever seen in the U.S. — sometimes as many as 10,000 birds.
Red knots (Calidris canuta) have a disjoint breeding distribution that determines their choice of winter locations and migration routes. The rufa subspecies visits the eastern U.S. though for most of them the final winter destination is the southern tip of South America.
The islandica subspecies spends the winter in the UK and western Europe after breeding in Greenland and Ellesmere Island, Canada.
Now in non-breeding plumage they are no longer red. The British call them “knots.” The flocks are spectacular!
A magical mindful moment with a flurry of knots! ?
As waterfowl arrive on migration it’s interesting to note that some families travel together, others do not.
Bird parents and offspring stay together during a nesting event but among most species the families split up after the breeding season. Notable exceptions are swans, geese and cranes which stay together as a family unit. The youngsters learn the route and wintering grounds from their parents. If their parents don’t migrate neither do they.
Above, a tundra swan family comes in for a landing at Middle Creek. The youngster (gray head and neck) is still following his parents as they head north in the spring.
Each duck species has its own migration strategy but that doesn’t mean they travel in family groups. For many, fall is the time to meet and greet the opposite sex. Mixed flocks of gadwalls (Mareca strepera) pair up while they travel. According to All About Birds, virtually all female gadwalls have a mate by November.
For birds, traveling as a family is the exception.
Some always travel alone.

November is a good time to see migrating gulls and waterfowl in southwestern Pennsylvania. Most are common but a few rare ones can fool you.
We always see Bonaparte’s gulls (Chroicocephalus philadelphia) at local lakes and rivers as they head south for the winter. Every once in a while there’s a rare look-alike, the back-headed gull (Chroicocephalus ridibundus). Originally from Europe, some now breed in maritime Canada and New England.
At top, a black-headed gull perches on the Eiffel Tower in Paris. In winter neither he nor the Bonaparte’s have black heads, however the amount of black-on-white varies.
Below, Geoff Malosh photographed a black-headed gull at Moraine State Park on 1 December 2017 (embedded from Macaulay Library). Notice that this gull has more black on its head than the gull at top.
As much as they look alike, the big difference between black-headed gulls and Bonaparte’s is the color of the bill. Black-headed gulls have red bills, Bonaparte’s have black as shown below.
One of these Bonaparte’s gulls is using his black bill. Check the color to know who he is.
In the meantime, keep an eye out for unusual birds in the Pittsburgh area. There were eight surf scoters (Melanitta perspicillata) at the head of the Ohio River on Saturday 31 October. The photo below is embedded from Amy Henrici’s checklist. Click on the image to see the original.

In eastern North America our chimney swifts (Chaetura pelagica) land every evening to roost in chimneys. In Eurasia and Africa the common swift (Apus apus) stays airborne for 10 months of the year!
No one knew this until Lund University in Sweden attached geolocator tracking devices to common swifts in 2015. When the swifts returned from their winter range in Africa the Swedes recaptured the tagged birds and found that most had not landed since they left!
Since common swifts spend so much time in the air and can live for 20 years an individual swift may fly 3 million miles in his lifetime. Wow.

Now that the breeding season is over birds have gathered for migration and the winter.
Early this week 50 common grackles leapfrogged over the trees and forest floor as they searched for food and bathed in Panther Hollow Run. (This photo gives you an idea of their abundance.)
Cedar waxwing numbers peaked in Schenley Park in early October when they devoured most of the porcelain berries. They’ll spend the winter further south, for instance in Memphis, Tennessee where this photo was taken.
Pine siskins were everywhere a couple of days ago. Are they still visiting your feeders? Where will they head next?
Starlings numbers are building in Pittsburgh as northern visitors arrive. Soon there will be thousands.
Crow numbers are building too. Last weekend I counted 2,400 but more arrived last night. Eventually the flock will look like this video from 2011. Where will they roost? Stay tuned.
Watch for spectacular flocks this fall. Let me know what you see.
