Nighthawks were once common in cities throughout New Hampshire, where they nested on gravel roofs and fed on insects attracted to city lights. In recent years, these acrobatic birds have disappeared from many New Hampshire towns, but they still nest in Keene. Help keep track of this charismatic endangered species by joining us for an evening of nighthawk monitoring in downtown Keene. We’ll start indoors with a brief introduction to nighthawk identification and ecology, then break into teams to search the twilight skies.  Rain date is June 12th.
