Away from Santa Clara County on April 22:
“Large straggly flocks flying north close to the water were Brent geese. There were also birds very high and in some kind of strung out formation. They may have been Brents but I have seen cormorants like this – although not in their hundreds as these flocks numbered.
“Other groups had about a dozen per flock, flew close to the water and looked like divers. I fancied red-throated from a slight drooping of the heads. Large straggly flocks of smaller birds completed the procession – scoters?
“None of these was really close enough to get any more than an impression of their general colour scheme. The sun was also coming round to behind them to make matters more difficult.
“Ideas, anyone? In any case it was certainly a sight worth seeing.”
