I live west of Eugene near Fern Ridge Res and we get a large influx of Robins every year between about Feb 10 and Mar 10. Most are overflights. We are apparently on a flight path to some huge roost to the south. We regularly have 100's pass over the last half hour of the day during this period with peaks occurring the last week of Feb. I've had over 1000 a few times and over 2000 at least once. Peak count so far this year has been 200. I'll be counting Apapanes and Iiwis the end of Feb this year so will miss the big numbers of Robins at home.
