The female TUFTED DUCK reappeared at the pond behind the Nob Hill Market in Redwood Shores today. I was getting a great view of the Tufted Duck in the flock of Canvasbacks and Lesser Scaup for not quite thirty minutes when a person with a dog walked close to the shoreline behind the market flushing the flock. Most of the flock flew off to Bair Island. What waterfowl stayed did not include the Tufted Duck. There were still some Green-winged Teal along the shoreline. Another teal was showing a bold white stripe across the lower scapulars and pale facial lines, but these features do not always rule out a intergrade with Eurasian Teal. Getting a better angle on this individual there was a partial vertical bar on the fore flanks, as expected on a intergrade. Although some intergrades have only shown a hint of a vertical bar on the fore flanks which could be easily missed.
A hybrid adult male Eurasian x American Wigeon was noted along Belmont Slough.
I was able to get in one seawatch from Moss Beach, as it has been dead. There has been no feeding frenzies. There were several Northern Fulmars following fishing boats and a Pomarine Jaeger was noted.
On January 29, there was a movement of many Herring Gulls coming in from the ocean and stopping at Crystal Springs Reservoir. During the time, there were up to ( 2,000 ) gulls coming and going. ( 800 ) Herring and ( 70 ) Thayer's were in with Glaucous-winged and California Gulls. Most of the gulls headed towards San Francisco Bay.
Ospreys are becoming a regular sight on the bayside in the county. In a one hour period from Coyote Point to Bair Island there were ( 3 ) adults.
