Too bad about the white-out BG. Otherwise, great IQ with your teleconverter, Troy; your plover is tack sharp. I appreciate your typical good low perspective, and I like your record of a black-bellied still with some hints of breeding plumage.
As Artie pointed out to me in All About Birds, the vestigial hind toe clinches the ID as BBPL. It's a great shot, looks like you got the fill flash just right. I like the light BG -- gives it kind of a high key look.
