I've had turkeys sit so tight that while judging pointing dog tests, the dog would go on point and we, as judges would holler to the gunners you can't shoot as we flushed a hen and her poults.
On a puppy test. I went to flush the bird the pup pointed. Only to get my hat knocked off by a Tom.
Amazing how something that colorfull can blend in its surroundings and disappear.
