The onk-a-chonk call of the American bittern at Market Lake Wildlife Management Area was close and unmistakable. In fact, it was almost like a Clint Eastwood/Dirty Harry taunt, “Go ahead punk, try and find me.” And try I did, looking for a bird so well camouflaged that even its behavior of pointing its bill straight to the sky mimics reeds and cattails. Even when calling, this bird can be very hard to find indeed. I finally gave up. Again.
