California Waterfowl Review Featuring Greater White-fronted Goose, Common Goldeneye and Cinnamon Teal

[Bay Area, CA. Early 2016/Late 2015]

Envision traversing the Western United States from the mountains of the Sierra National Forest to the Pacific -- entering the sea through San Francisco Bay. 

In the ensuing journey of transitions in the landscape from canopy, mid-story, shrublands, grasslands, marshes, mudflats, to water bodies and finally ending in a vast marine expanse we breeze past a succession of birds such as warblers and jays, tanagers and flycatchers, grosbeaks, sparrows and quail, herons and rails, shorebirds to waterfowl and finally the pelagic species. Every habitat supporting its own rich collection of birdlife that is superbly adapted to its particular niche in the environment. 

In this "habitat spectrum", we pause briefly to explore the extensive water bodies of the Bay area and the tremendous variety of waterfowl that can be observed there, including iconic species such as:

  • Greater White-fronted Goose
  • Green-winged Teal
  • Cinnamon Teal
  • Northern Shoveler
  • Common Goldeneye
  • Bufflehead 
  • Canvasback
  • American White Pelican
  • Brown Pelican
  • Gadwall
  • American Wigeon
  • American Coot
  • Eared Grebe
  • Ruddy Duck
We start with the Goose:

Greater White-fronted Goose has a huge range but is uncommon in the Eastern US. It breeds in the Arctic and winters in California.

The "white-fronted" refers to the white border to the bill on the face of the goose. This is a brown goose with black patches on the breast. The legs are bright orange.

This spectacular individual was observed at the Sunnyvale WPCP.

Our smallest dabbler is the Green-winged Teal. This blogger has not usually had the opportunity to observe this beautiful duck out of the water -- yet, here at Baylands Preserve in Palo Alto, this resplendent male was glistening in the early morning sun:

Every birder has a favorite waterfowl species -- for anyone living in North America, Cinnamon Teal has to be high on that list:

The male's deep cinnamon-chestnut color is unforgettable. The female is predictably plainer. Both were observed at Sunnyvale WPCP.

Among the various similarly shaped ducks, one catches the observer's eye on account of the prominent "honker" of a bill -- this is the Northern Shoveler:

This is a global species with a large range and instantly recognizable thanks to its uniquely shaped bill.
The male Common Goldeneye is a stunning small duck that nests in tree cavities:

The female is a warm brown but also shows the pale iris:

The male Bufflehead's coloration shows subtle shades of purple and green when the lighting permits:

Unlike the dabbler teals and shoveler, the Bufflehead, Goldeneye are diving ducks as is the Canvasback:

While the Canvasback is large relative to the Bufflehead or the Common Goldeneye, it is decidedly dwarfed in relation to the American White Pelican:

These magnificent creatures were seen at Charleston Slough. We have only two species of Pelican in the country -- and both can be observed here in the Bay Area.

The 2nd pelican species, Brown Pelican is found on all three coasts (Pacific, Atlantic and Gulf). However, the Western race of the Brown Pelican is somewhat distinctive with its brighter colors -- the male sporting a bright red gular pouch:

The silvery white accents, red bill and cream-colored head contrast well with the brown plumage of this acrobatic plunge-diving feeder:

Finally two more ducks that sometimes can be confused: Gadwall and American Wigeon:

American Wigeon:

Other species included an American Coot:

An Eared Grebe in winter plumage:

In Spring the Eared Grebe will be completely transformed:

The breeding colors of the grebe were witnessed several years ago at Bolsa Chica in coastal Orange Co.

Finally, a Ruddy Duck:

Our waterfowl species -- dabblers, divers, pelicans and the like -- are a remarkable collection of birds that have mastered not only the air but also the water -- and, for the intrepid birder there are few places more rewarding than the many inlets, water bodies and channels in the San Francisco Bay area to observe them in their natural habitat.

An exhilarating display of diversity of species and plumage detail, Hemant. The Sunnyvale WPCP upgrades will certainly be a boon to the wildlife it supports. Your Bolsa Chica Eared Grebe is my favored subject in this article. I've advised Tom to be on the lookout for the Great White Pelican's possible return to Ding Darling NWR.

Lovely blog! I can't wait to see the ducks - soon they will start to arrive, I love this time of the year.
