[EBB Sightings] Arrowhead Marsh today

Hi. I birded Arrowhead Marsh for a little over an hour today (1:30 PM - 2:45 
PM). Still very high tide, excellent birding. There were Soras and Clapper 
Rails on grassy mats in the water, and a huge gathering of Willets, Marbled 
Godwits, dowitchers, and Black-necked Stilts nearby on a wooden walkway over 
the marsh. The marshy areas farther out had scaup, Canvasbacks, a few Surf 
Scoters and American Coots. The "goose field" had numerous Canada Geese, a 
small group of Greater White-fronted, and at least three Cackling. Also an 
apparent hybrid Swan Goose/Canada Goose. The nearby shoreline had scaup 
flocks, Common Goldeneyes, a flock of Surf Scoters, and the PACIFIC LOON. 
The loon was on the water near the dirt jetty. The ponds behind the fence, 
across the street from the marsh/bay, had Northern Pintail, Northern 
Shoveler, Mallard, Green-winged Teal, American Wigeon, and a single 
rufous-morph female EURASIAN WIGEON. Also a large flock of loafing gulls 
that included Ring-billed, California, Western, and Glaucous-winged.
