Wintu Audubon’s First Mini Christmas Bird Count

Birders at CBC

A group of six youths and thirteen adults split into three teams that scoured Turtle Bay from the Highway 44 bridge to above the Sundial.  They were looking for something, and they found it in profusion: Birds!  It was Wintu Audubon’s Mini Christmas Bird Count for Youth and Beginners, and December sunshine after the cold snap made for a warm show of feathered flutterings from all over the rainbow.

The three teams each took an area and tried to identify and tally every bird they found in ninety minutes of searching.  They totaled 791 birds from 57 different species, from stately herons and egrets, to squabbles of ducks down from the arctic, to “now-you-see-me-now-you-don’t brushbirds who, being hungry in the leafless trees, made themselves delightfully more visible than they often do.

A few highlights: an unstately heron gulping a fish that really shouldn’t have fit.  An immature bald eagle in silhouette on a snag, being harassed by a handful of half-hearted crows.  A resplendent Eurasian wigeon gleaming in the sun.  A brown creeper finding its insect breakfast in the fissures of oak bark.  A flock of cedar waxwings enjoying wild berries along the river.

 The species most counted, at ninety-nine, was Buffleheads, black and white diving ducks who typically nest in northern plains pothole country but come to our area for the unfrozen water in winter.  The different counting teams might argue about which was the rarest bird to find in Redding in winter—perhaps the osprey, or the brown creeper or Hutton’s vireo, perhaps the Eurasian wigeon.

The Mini Count was part of Wintu Audubon’s Youth/Beginner Walks, which meet the second Saturday of every month at 9:00 a.m. at the Turtle Bay Monolith.  Binoculars are provided.  The public is invited.

Burrowing Owl Named Audubon California’s 2013 Bird of the Year!

Burrowing Owl

It’s official! From the California Audubon’s Press Release:

San Francisco – One of California’s most beloved owls today was named the 2013 Audubon California Bird of the Year. The Burrowing Owl – which nests underground in burrows rather than trees – received the designation after receiving more than 48 percent of votes cast during an online poll this fall.

The Burrowing Owl finds its home in dry open areas with low vegetation, sometimes in vacant properties along the urban and surburban edges where bird enthusiasts delight in watching them. However, it is exactly this type of habitat is often targeted for development, putting the Burrowing Owl in a precarious position.

More than 22,000 votes were cast in this year’s Bird of the Year poll. The Burrowing Owl finished with 48.3 percent of the votes cast. Thanks to all of you who voted for my favorite bird, the Burrowing Owl! We hope this adorable little bird will get much more attention in the coming year because of this designation.

Ross’s Geese at Sacramento National Wildife Refuge

Every autumn, tens of thousands of Snow Geese arrive in California’s Sacramento Valley following their long journey from the Canadian Arctic (click on photos for full sized images).

Waterfowl numbers at the Sacramento National Wildlife Refuge Complex may exceed two million by December, after the wetland areas of the Klamath Basin and other areas to the north become frozen. Snow and Ross’s Geese winter there in the tens of thousands.

Currently, about 95 percent of all Ross’s Geese nest in the Queen Maud Gulf Migratory Bird Sanctuary in the central Canadian Arctic. The main wintering area for Ross’s Goose (Chen rossii) is presently in the Central Valley of California, though increasing numbers winter in Arkansas, Louisiana, New Mexico, Texas, and the north-central highlands of Mexico1. Map courtesy of Terry Sohl at South Dakota Birds and Birding.

The Ross’s Goose is the smallest variety of the white geese that breed in North America. They look like a small Snow Goose but they have a shorter neck and a rounder head. At the base and sides of its smaller beak, the Ross’s Goose has species-specific vascular wartlike protuberances or caruncles which become more prevalent with age1 (more apparent on full sized image).

They also lack the “grinning black lips” of their larger Snow Goose cousin.

They are fairly easy to tell apart in a mixed flock by their size and the lack of the “black grin”

Their heads are usually whiter than the larger Snow Goose at winter feeding grounds, probably because their smaller bill is adapted for feeding on short blades and shoots of grasses and sedges as opposed to the roots and tubers the larger geese dig through the mud for.

The bird scratching itself in the background of this photo is a juvenile, still showing some gray feathering on its head and nape.

It looks like nap time for these Ross’s Geese…

at least until something stirs them into flight!

This is a video I shot at the refuge on December 1st, 2013.
