I noted in my post yesterday that I saw many Swainson's thrushes in Rock Creek Park. There were several in the maintenance yard, as well as in the woods around the nature center. Well, this afternoon, I heard one singing in a small park near Union Station, hardly ideal thrush habitat! Apparently there was quite an influx at Rock Creek Park this morning as well. One report estimated that there were 40 just in the small area birders normally cover.
