American Avocet

I did a post on an American avocet I saw near Alamosa, Colorado in August 2014. It was in breeding plumage with a rusty head and neck. In January 2021 I was at the Salton Sea State Recreation Area in southeastern California and saw several avocets in their more-drab non-breeding plumage: the rusty head and neck is a more drab gray and white. 

Grayish/blue legs visible while it dives.

One of the more fun characteristics is a very long, thin bill that is upturned at the end. 

I was also a little surprised about how large they are in comparison to other birds.
