They’re amazing numbers - it’s likely you’re seeing post breeding juvenile groups. How and why these groups form and function is part of Bernd Heinrich’s classic studies. Two of his books - 'Mind of the Raven' and 'Ravens in Winter' are both worth reading on this. (Especially the latter - one of

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

Interesting bit of information. I seem to recall that it's said that one way to separate Chihuahuan from Common Raven in Arizona / New Mexico is that only Chihuahuans occur in flocks. Maybe that is true in that area, but could this cast some doubt on that? I didn't think about it all that much

There has been large groups of Common (really) Ravens at Minnewaska State Park near New Paltz, Ulster County for the last few years. Scott Baldinger has been keeping close tabs on them with his regular Tuesday Early Birders Walks. Richard Guthrie On Fri, Dec 1, 2017 at 3:19 PM, Kevin J. McGowan

Nice sighting.  It is very rare for around here to see so many in a flock, but out West they are frequently seen in medium sized flocks sometimes much larger usually at a feeding site such as a dead large mammal.  I have personally seen a flock of 80-100 in Unity, Maine, back in the mid 80's

Undoubtedly a winter non-breeder group. I remember less than a decade ago my first encounter in the state with such a group in eastern Cortland County. I realized that there were now enough ravens breeding in New York that the juveniles could find each other. Looks like that might be true in

On larger raven flocks (probably juvenile "gangs") See Bernd Heinrich's excellent "Ravens in Winter" (1989). Rick Sent from my T-Mobile 4G LTE Device Original message From: Shaibal Mitra Date:12/01/2017 2:42 PM (GMT-05:00) To: "NYSBIRDS
