Last week I had a winter-plumage Horned Grebe for a new yard bird, and it spent several days out back, but I haven't seen it since the beginning of the week. Does anyone know what their migration "schedule" tends to be? I'm guessing that the warm weather may have prompted it to leave, but we still have a flock of 8-10 Buffleheads actively feeding, so maybe not.
It's been fun to compare the feeding activity of the two species. The Buffleheads submerge for only about 10 seconds, and they bob back up just a few feet from where they went under. The grebe would submerge for 30 seconds or more, and often came up many yards away. One day it went all the way across the creek in one dive.
