[nysbirds-l] Any other passerines sound like Common Nighthawk?

Yesterday I heard the call of a Common Nighthawk, but what I saw didn't seem to match. The bird was quite high in an Oak, but what I saw was white belly and gray back. The call left with the bird I saw. Any ideas? Ruth Hyman Nassau County -- NYSbirds-L List Info:
