I don't think I've ever seen so many crows in a city as I have in Bucharest, although Kyoto may rank a close second.
Romania is home to the Hooded Crow - an ashy gray bird with black head, throat, wings, tail and thigh feathers, as well as a black bill, eyes and feet. But its coloration is about all that sets it apart from the usual black crow; an omnivorous and opportunistic forager and feeder.
I've seen these crows in flight in very large groups, but unfortunately my camera did not capture them. These two loners join Misty's Camera Critters.
