We observed an interesting movement of 19 Black Vultures at Rockefeller
State Park Preserve this morning on Saw Mill River Audubon's 2nd Mon bird
walk there.

Twelve drifting together north and 7 others seen around the Swan Lake
area.

There have been good numbers of Black Vultures with the Turkey Vulture
roost just 6 mile N by the Village of Croton-on-Hudson but not as many BLVU
recorded there in last couple of months with the temperature swings.

Noted this ref in Cornell's Birds of North America online resource: "Black
Vultures also engage in short-term, local movements when weather becomes
unfavorable, retiring ahead of adverse conditions and returning when
conditions improve."

Among other observations this morning at RSPP were:
*  a small group of six Snow Geese headed northwest over Swan Lake,
*  Northern Cardinals and Song Sparrows both now singing,
*  and -- always enjoyable -- great looks at three adult Bald Eagles.
