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." https://birdsna.org/Species-Account/bna/species/blkvul/distribution 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. eBird list here: https://ebird.org/view/checklist/email?subID=S42702484 Anne Swaim Saw Mill River Audubon www.sawmillriveraudubon.org -- NYSbirds-L List Info: http://www.NortheastBirding.com/NYSbirdsWELCOME.htm http://www.NortheastBirding.com/NYSbirdsRULES.htm http://www.NortheastBirding.com/NYSbirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/[email protected]/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/NYSBirds-L 3) http://birding.aba.org/maillist/NY01 Please submit your observations to eBird: http://ebird.org/content/ebird/ --
