Since there have been so many Nighthawks reported this year and so much interest, here's a website with a lot of details about them you probably don't know: http://birding.about.com/od/birdprofiles/p/Common-Nighthawk.htm And here are some pictures you can compare those details against. Not everything can be seen here, but several of the features of the males are visible. I looked through all my pictures and I can't find a single female, based on this article. Maybe the males migrate first. Or last. https://www.dropbox.com/sh/bi672o1kqmhnkaa/AADVqWj71NoSn7ftXiv8Rj73a?dl=0 Don Morgan, Coventry, Ct mntncougar@aol.com
