Thousands of Grackles

Brown-headed Cowbird flock (photo by Chuck Tague)

This morning outside my window I watched a flock of thousands of common grackles streaming toward Schenley Park.  The flock moved in a long thin line so it took several minutes for it to pass.  Just as I assumed they were done, even more appeared.

You can get an idea of it how they looked from Chuck Tague’s picture of a brown-headed cowbird flock.
