American Wigeon Pair Bonding

Like many other species of waterfowl, American Wigeons have a bunch of interesting behaviours that peak during the breeding season. In this image a bonded pair respond to a possible competitor. Although it seems from the image that the pair is hissing, the male is actually giving his “fast-whistle” vocalization to let the incoming male know his female is taken. Male whistling sounds are quite high-pitched and “airy.” The hen is giving an “inciting call” at the same time. It’s a social courtship call most often used on the water. It sounds more like a growl than a whistle. They are akin to the hisses or quacks that other waterfowl species often use in territorial matters. The pair are doing a “wings-up” courtship display at the same time. It is characterized by their primary wing feathers being crossed over the back and most often happens on the water as part of their pair bonding.
