At first glance these plovers looks like they’re doing yoga. Actually they’re preening. Birds spend a lot of time preening each day in order to maintain their feathers, which are their only clothes. Lacking a brush and comb, they use what they have. This cute Snowy Plover is leaning over its back and pulling some feathers through its bill. The Semi-palmated Plover has one leg raised and is about to bring it up over its left wing and scratch its head. It’s no wonder it hasn’t fallen over. Don’t try this at home.
