The black-bellied plovers should be one of the easiest shorebirds to ID, right? But a few factors to consider are; 1) other plovers species have black bellies. 2) black-bellied plovers don't always have black bellies. How black a belly they have depends on age, time of year, breeding cycle, and numerous other factors. This is a breeding male Black-bellied Plover.
This is (I believe) a juvenile black-bellied plover. Personally, I recognize the big, round eyes more than the striped or mottled plumage. The white belly is another clue.
I think there is a female, a male, an immature, and a juvenile - along with various other species. What do you think?
Breeding male, most definitely.
Black-bellied Plover family in flight. I have no clue who's who here. How about you tell me?
