The Delaware-Otsego Audubon Soc. has been using trail cameras baited with road-killed deer to determine winter Golden Eagle presence in the Catskills and central NY over the past few years. The numbers of ravens coming in to these sites is astonishing--hundreds at a time on occasion. So many that they can strip a full grown deer carcass to the bones in a day.

Here's a link to a photo of a modest congregation at one site: https://photos.app.goo.gl/a3EAuqzCZgYkjN6D3. Andy Mason On 12/1/2017 3:25 PM, Andrew Block wrote: > Nice sighting.
