Flock was hanging out on beach for at least 15 minutes, standing / run/walking; flock included males with distinctive black face / bellies, heavy beans, and clean white tails in flight, also sound ID by Merlin (at 1:10 in the recording). Did not observe black armpit however no golden plummage observed. This was a solid estimate count (half of flock had 30 birds in it).
