This is a juvenile Black-Bellied Plover. Note the bright white belly, brown head, and brown polka-dotted feathers.
Here is the little guy's Mom. Of course!
This black and white (or maybe grayish brown) guy is his brother.
This is his sister. She is brown speckled, but with a reddish belly. She has a longer tail and black tail feathers.
This grey bird with a facial mask and crew cut is the little bird's cousin.
And this is his Dad! See how easy it is to recognize Black-bellied Plovers? Now, can you ID the terns in this photo? Terns are easy, too!
PS. I'm joking. I'm not certain of the ages, sexes, or even the species of any of the birds pictured here!
