197. Mareca americana, (Gm.). — Bald-pate; American Widgeon. 



The Widgeon is an abundant winter sojourner of the valleys, at which

 as late as May 28, 1878.

The Sprig-tail is a common winter sojourner of the valleys. A pair 

 was observed on May 28, 1878, at Stockton. There was at that time a

The Spoon-bill Duck is a common, though never abundant, sojourner

 ducks — in fact, is usually the last of them to leave.

 shot it in winter as high up as Murphy's.

I am not certain in regard to this species, but think I have seen many
