Commong Nighthawk or Eastern Whip-poor-will - Philadelphia, PA in Help Me Identify a North American Bird Posted July 19 Hello, My friend saw this bird in the Kensington area of Philadelphia last Friday afternoon (July 15) . Not anywhere close to a park. I have never seen a nightjar or nighthawk so I'm not sure what it is. But I thought it was a nightjar because the tails aren't the swallow-ish pointed tails that are the trait of a nighthawk. It also looks very young. Any help is much appreciated.
