My friend Chris (my friend Chelsea's husband) is also an avid birder and sends me cool pictures from time to time. They recently moved to Pittsburgh and these are the first wildlife pictures he's sent from there. (When they were living in Mashpee on Cape Cod he used to send pictures of hawks lingering near their feeder.)
I know very little about nighthawks but he explained that it's very rare to see them perched so he was obviously very excited:
He said it's been hanging around for a while actually. I'm sure they must be interesting to watch!
