The hawk watch today in New Haven produced 111 migrating raptors, highlighted by 62 Broad-winged Hawks - all but one in several kettles (swirling flocks riding aloft on thermals) during the 10-11 hour.

10/30. Stratford, Beacon Point Rd, stratford Greenway. Yesterday afternoon Stefan Martin alerted me to a variety of shorebirds on the tidal mudflats here. Among the many BbPlovers and Dunlin were 1 AM GOLDEN PLOVER, 1 DOWITCHER sp, and a PECTORAL-type Sandpiper. SM thought the latter looked “very rufous” through his bins.

Much to the delight of the winter bird ecology field course participants currently visiting QUBS, it appears to have taken up a territory there. BARRED OWLS can be heard most nights as they begin singing in anticipation of the breeding season. A lone PINE SISKIN visited the feeders at QUBS for one afternoon; they remain scarce in the region.
