I am not discounting the premise of this post however in upstate new york I am seeing flocks of turkeys which I have never seen until recent years ... also bald eagles have reappeared in numbers again not seen until past 5 years or so ... this is partly due to the drop in game hunters as well as a fall off of farming with many abandoned farms and fallow acreages going to scrubs ... also due to the ban on DDT decades ago ... so certainly some type of birds are seeing a resurgence
