Hopefully these are isolated incidents we are hearing about.
I was out this past Saturday (Holyoke area), and the birds were as jumpy as ever. Didn't see as many, but think that's because they were in the corn feeding. The snow drifts were worst on the north and west edges of the fields, and most of the cover had little to no snow in it.
I asked one of my buddies from the area if he thought the past storm hurt pheasant numbers. His reply was "the birds are fine, it's my wheat that I'm worried about." I guess the wind sandblasted the wheat for two days. He said it will still grow, but it definitely hurt it.
If you're wondering, we only came home with two pheasants. We should have had at least two more, but you know how that goes. We did see decent numbers of birds, but they love flushing out of range this time of year.
