I estimated that at least 10,000 blackbirds flew over my house this evening on their way to a roost to the north of me. 95% were grackles, with red-wings, cowbirds and starlings making up the rest. The flock has been growing daily - yesterday about 7500 birds (virtually all grackles in one huge flock) went over and the day before 4000+.
These sightings were made today from 6:35 to 6:45 p.m. near Lakeridge and Reach Sts.
