- North Central Montana, bloody cold!
Jim, nighthawks are amazing birds. My Dad called 'em bull bats. I was turkey hunting last week, listening to some nighthawks before daylight and watching them when it got light enough. I don't know if they echolocate like bats but they make a chirp or beep every few seconds and then dive down to seize their prey and make that unforgettable "voom" sound as they culminate the dive, all done in twilight or darkness. I've heard that sound is caused by their feathers but I always thought it might be their jowls flapping in the wind as they open their huge mouths. I'll have to look that up.
