Watch For Amazing Flocks This Fall

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.

  1. I still have a flock of about 36 pine siskins coming to my feeders. (North Fayette Twp., Allegheny Co.)

  2. I’m not sure if this is only a shore town occurrence, but tree swallows have been amassing in decent numbers for the past couple of weeks. They are always a treat to see. Do tree swallows frequent Pennsylvania in numbers in the fall?

    1. kc, tree swallows seem to be a shore-related phenomenon in the fall. They certainly don’t visit western PA in the numbers seen at Cape Cod, NJ, etc
