Handsome and Horny, Northern Pintail

Any duck this good looking ought to be content with the ladies who naturally fall for his charms, right? Not the Northern Pintail, about whom, National Audubon Society Field Guide to North American Birds says,"Male Northern Pintails are aggressive, often forcing their attentions on females of other species." Seems kind of like the handsomest man in town breaking into the zoo and molesting the purple-assed baboons!
