This Charadrius plover was at Bolivar Flats on July 26,
2008 - I had heard what sounded like a CRPL call among SEPL calls from a loose flock of small plovers flying by me - they landed some distance away, and by the time I caught-up this flock had disappeared among hundreds of small shorebirds feeding on the flats - thus I have no idea if this individual gave the CRPL-like call. Note the black
reaching/surrounding the gape-point on both sides of the bill; the bill
shape and length; the lack of a visible eye-ring in any photo (however the strong lighting might make this harder to detect); the narrow black mask; the apparent lack of inner toe webbing in some photos:
