2009 Yosemite Christmas Bird Count: Dec. 20 (details below)

Tens of thousands of volunteers across the Americas join together annually during the Christmas Bird Count. The event provides a full day to celebrate birds. Since 1932, Yosemite's participation has contributed more than 90,000 observations to the conservation event.

During the 109th Yosemite Christmas Bird Count on Dec. 14, 2008, participants identified 3,028 birds of 65 species. Highlighted by the 32 birders, separated into six groups to cover large expanses of the park, were a northern goshawk in the west end of Yosemite Valley, a merlin in Foresta, a northern mockingbird in El Portal and two red-breasted x red-naped sapsuckers--in El Portal and Foresta. Nine raptors, including sharp-shinned hawks, Cooper's hawks, and peregrine falcons, were on the list, too. And, more than 500 band-tailed pigeons and American robins plus almost 400 Oregon dark-eyed juncos were spotted.

Past highlights include:

• A record 1,100 band-tailed pigeons counted in 1971
• A record 560 mountain checkadees in 1972
• A record 483 golden-crowned kinglets in 1953
• Two rare hooded mergansers spotted in 1940
• Great gray owls observed during past five annual bird counts

When bird-watching, experienced birders confidently identify birds by just a glimpse. (See illustrations of Yosemite's most common species.) Remember that a bird’s feathers change as an adult molts into its winter plumage. For many species, a male bird’s winter plumage is dull compared to his colorful plumage in the spring when he is interested in attracting a female with whom to mate. Also, note subtle nuances in a bird’s song or call—long trills or short chips. In the winter, birds rarely sing but make call notes to defend a territory, announce the presence of a predator, or to keep up with a mixed-species foraging flock.

The next Yosemite Christmas Bird Count is Dec. 20, 2009. To attend the full-day event, bring binoculars, a field guide, lunch, plenty of warm clothes and sturdy shoes. A small fee typically exists to support the publication of count results in National Audubon Field Note, which will give the highlights of the International Christmas Bird Count. Plan to be outside all day, from around dawn to dusk. An annual compilation potluck dinner closes the day to allow participants to share Yosemite birding highlights. To participate, you must register in advance. Contact the Yosemite Christmas Bird Count Organizer, Sarah Stock, by e-mail or by phone at (209) 379-1435.
