[EBB Sightings] Melanistic willet at Hayward shoreline

Yesterday there were dozens, maybe hundreds of willets at Hayward 
Shoreline. There was one that looked different. Instead of the mottled 
gray-on-gray normal for mating plumage, this bird had all dark gray on 
its back. Much the same pattern as winter plumage, except the gray was 
much darker. Sort of a charcoal gray.

The head looked like a standard issue willet head, and when it flew it 
had the characteristic knock your eyes out black & white wing pattern.

About 3:30, in the Ora Loma marsh.
