Our predators are mostly nocturnal. We have daytime hawks, at night, coyotes, fox, black bears, possums, owls, bobcats, house/barn cats that roam the area at night. This is the time when most of the young are fledgling and this is when once in a great while I might hear something that has made contact with the fence. The predator youngsters are now more or less on their own and wow there are birds here, mom & dad didn't show us this, ZAP.
