With a particularly dainty Calfornia Gull in foreground.

观察细节

Conservative count as Glaucous-winged hybrids were prevalent, but at least 3 promising candidates. 2 adults and 1 3rd cycle with pale eyes, streaky heads and black undersides to primaries. One of the adults had an interesting molt - the head was largely white while the tail and flight feathers were still being molted. The flight feathers appeared to follow a "staffelmauser" pattern.
