Radnor Lake State Natural Area
May 18, 2013

A large group turned out for the NTOS morning field trip to Radnor Lake.  Highlights were 2 CONNECTICUT WARBLERS, one of which was cooperative to a nearly unprecedented degree. It sang on a close open branch in full view of the entire group, allowing numerous pictures and even some video.  At one point it was nearly right over our heads. There was also 2 MOURNING WARBLER heard, one of which was seen briefly by some. Other highlights included a BLACK-BILLED CUCKOO which posed for photos and a nearby YELLOW-BILLED CUCKOO for comparison; great looks at CANADA and KENTUCKY WARBLERS; a large number of BLACKPOLL WARBLERS, male and female; and a face-off between a BARRED OWL and a Squirrel. An empid below the spillway, provided good enough looks to be identified as a TRAILL'S, but remained silent, so positive ID was not possible; however, he was foraging in willow trees, suggesting it was a WILLOW FLYCATCHER. Several of the birds seen were life birds for some of the group, including the Connecticut and the Kentucky Warblers. 74 species were seen, including 21 warbler species, and the Trail's and another unidentified empid.
