American Avocet Mating Displays
I’ve been fascinated by the mating displays of American Avocets ever since I first started photographing them almost five years ago. This innate and complex choreography is almost identical in different mated pairs and from year to year. The action happens quickly and is difficult to photograph well but I think I have enough decent images now to make an informative post about it. Not all of the photos are of the highest quality but I think each of them illustrates the behavior well. I’ll present several sequences of different birds that will illustrate most of the important stages of the process. I’m not going to include my techs with these shots -some of them were taken when I first started photographing birds and I made many mistakes in my setting choices. Knowing some of these settings wouldn’t help anyone. Avocets are monogamous and pairs form up in the spring when the female persistently associates with the male until she is eventually tolerated, then accepted as a mate. The female initiates copulation by the posture you see above. It’s called Solicitation Posture and in it she holds her neck extended far out and low. At times it’s so low that much of the head, bill and neck are under water as you’ll see in a later image. Once interested, the male performs Sexual Preening where he stands close to the female and extends his neck so that his bill tip can preen his breast (always on the side closest to her). You’ll see that part of Sexual Preening in a later image but…
