Re: [nysbirds-l] Astonishing High Count for Common Raven, Suffolk Co., LI
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 my favorite books) As in interesting corollary - I’m also seeing way more ravens right now back on my upland farm in the northern UK. They were rare here before I moved to the US. The winter courtship is well underway and nesting will start soon. Although nothing like your numbers, the range expansion seems truly widespread.

Re: [nysbirds-l] Astonishing High Count for Common Raven, Suffolk Co., LI
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. When I began birding in the 1980s, it was necessary to travel to the Adirondacks to have a chance of seeing a raven--what a range expansion!

Re: [nysbirds-l] Astonishing High Count for Common Raven, Suffolk Co., LI
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 a few weeks ago when hawk watching near Port Jervis, NY, but at one point a group of 9 or 10 Common Ravens flew by. A couple of years ago, upon coming back from this trip, I reported on up to 40 apparently going to a roost near the pull off south of the Bear Mountain Bridge. No sign of that on this year's trip (although up to 50 Black Vultures likely going to a roost closer to the bridge made for an impressive sight).

Re: [nysbirds-l] Astonishing High Count for Common Raven, Suffolk Co., LI
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 flying over the Unity College campus. It blew my mind when I realized they were ravens. It's so great to have them around here. Andrew Andrew v. F.
