I made it to the vulture roost on Putney Rd just in time, got there at 4:30 PM and already saw them circling over the trees - it must have been three or four. I grabbed my camera and started shooting. A couple of years ago black vultures were sighted at that roost but on several occasions I had waited in vain there to see them. I was lucky this time!
Coming in for a landing..... I stayed for a few more minutes but after that only saw turkey vultures.
