This presumed American Golden-Plover
was with a dozen other P. dominica at Tule Lake in Corpus Christi, Texas on April 01, 2006. This was one of two individuals that seemed to have extremely long tertials, and perhaps it is not a coincidence that these two birds were also different from the others in that they were quite advanced in their pre-Alternate molt, while the others were still in almost complete basic plumage.
Note the extremely long tertials (which may not be fully-grown, as T3 should extend obviously beyond the others) that are within a millimeter or three of the actual tail tip. Also note the quite extensive pale markings in the fresher upperparts feathers.
