This Common Nighthawk came in battered and thin from migration, and as you can see, he is none too happy about our efforts to fatten him up! We fed him our specialized baby bird formula for insectivores via syringe six times a day. A member of the nightjar family, nighthawks catch and eat insects in their gaping mouths while flying, much like Chuck-wills-widows. They migrate through Northeast Florida on their way to the tropics for the winter where insects are plentiful. Time was of the essence
