Upper Watts Branch Park for 5/16:�
The birds were scattered today but the highlights were TWO Olive-sided Flycatchers interacting at the beaver dam (dead trees just off the intersection of Nelson St. and College Parkway) and two Gray-cheeked Thrushes (just upstream) of the Newfoundland minimus subspecies. �One sang and gave a typical contact note. �They were noticeably different in appearance from the nominate in having warm brown upperparts and a blush of buff in the throat and in the weak eyering. �These birds can be mistaken for Bicknell's Thrush, but Bicknell's has warm brown only in the tail and primary edges contrasting with flat gray-brown above. �Both show buff in the throat as a rule. �So beware.
