Warning: woman with camera and a book on birds.
I believe these are Chinese Geese. Both of them, the brownish and the white, match pictures I see. The White Chinese Goose I compare to pictures on Bird-Friends; the darker one I've seen on so many pages and in books.
Bird lovers, perhaps you can help?
These pictures were taken at Averill Park in San Pedro on November 3. There were hundreds of Mallard ducks and quite a few geese. I think they are Chinese Geese but would appreciate corrections.
As for ducks, the non-mallards have me confused. My handy-dandy National Geographic book on Birds of North American seems to have given ducks short shrift. I see no Poofy Ducks, which is how my friend and I referred to these black and white duckies with a big cotton-ball poof of feathers on their head.
They are also called Crested Ducks. Wikipedia says they are descended from Mallards.
They come in a caramel and white variety too, as you can see below. According to the 10,000Birds website, those could be Buff Orpington domestic duck.
Mallards, I read there, are dirty birds, cross breeding like crazy, which may explain some of the other ducks I saw. Like a mostly black duck with the emerald green head of a male Mallard.
That's apparently a classic cross of Mallard and American Black Duck
.But Avian Web says that Crested Ducks come from South America, and they have a picture of a duck that looks a lot like the one below.
November 23 update: please check out the comment from Doug Peterson, who identified the black duck at left as a Cayuga, and the ones at right as a Fawn & White Indian Runner, both crested and none, and the crested duck above with the Mallards as likely a Crested Ancona. His blog provides a lot more information on them! That blog is words4It.com--don't know why it's not showing above.
