Piping Plovers are so darling! And as far as I can tell, you did correctly ID the bird. I wish we had them over here on the west coast.
As for the cute little image, you did fine; the two items I would add is, #1 if there is the option to get down lower to their level, go for it (very doable) and #2 use a longer lens (not as doable if you aren't a birder yet). :biggrin:
