PIBO MIGRATION SUMMARY May 21st - 31st, 2010
Connecticut Warbler

Migrants continued to move through the area in good numbers at the start of the summary period but then things tapered off considerably by May 26th and it remained generally quiet to the 31st.

The week started off on an interesting note with a Townsend's Solitaire observed flying over the tip at Fish Point on May 21st, then seen again at the reserve parking lot. This sighting is a PIBO 'first' for Fish Point and represents a very late Spring record.

Diversity at the Point peaked over the ten days on May 23rd & 24th when 64 species were recorded during the morning count periods including two Whimbrels at the tip (23rd), a Least Bittern at Peregrine Pond (23rd), and a male Connecticut Warbler banded on the 24th. A nice variety of other species were captured from the 21st-31st including steady numbers of 'Traill's', Least, and Yellow-bellied Flycatchers, Swainson's and Gray-cheeked Thrushes, along with ones-and-twos of Canada, Wilson's, and Mourning Warbler.

An Acadian Flycatcher (the second banded this spring) was captured on May 23rd and two singing males were recorded on the 26th. A female Hooded Warbler (banded) and a singing male Hooded were noted on the 24th and a Louisiana Waterthrush was found on census on the 25th.

The weather warmed up (20° C at dawn on the 28th) and migration activity decreased towards the end of the month, with just 32 species tallied on May 29th, along with similar results on the 30th and 31st. Despite these conditions, a few migrant species continued to filter through the area in moderate numbers including Black-bellied Plover and Ruddy Turnstone, a variety of flycatchers, both cuckoo species, and a steady stream of Cedar Waxwings, among others.

PIBO's next summary will be posted on June 10th.
