113 years later there are over 2,300 locations that participate each year, including Yosemite. Yosemite has been active in the CBC since 1932. As Sarah Stock, NPS wildlife biologist and coordinator of the Yosemite CBC, puts it “Yosemite’s CBC has become a treasured holiday tradition, a reunion with birding friends, and a way to play a small part in a big conservation picture.” The observations collected by the citizen scientists that participate in the count are compiled in a national database that can provide valuable information about the long term shifts in population and range of some birds.
This year on December 15, 2013, 63 participants divided up into 9 groups, each one with the goal of counting as many species and individual birds as possible in their particular area. Each group had at least one designated leader, a birding expert, who was responsible for the accuracy of the data. All day, the groups searched their respective areas, covering a 15-mile radius circle that included El Portal, Foresta, Yosemite Valley, and Chinquapin/Yosemite West. This year, a total of 2,754 individual birds comprising 69 species were recorded!
The fantastic day of birding started and ended the same, with the soft persistent hoots of a Northern saw-whet owl. The record number of participants had some great birding moments and highlights, including 11 raptor species (of which 4 were owls), two Western scrub-jays above 5,000 feet elevation, and 355 golden-crowned kinglets (including 242 in western Yosemite Valley alone)! The “birds of the day” included a merlin north of Foresta, a Western screech-owl and a Myrtle’s yellow-rumped warbler in El Portal, two Williamson’s sapsuckers, and a brilliant look at a pileated woodpecker (below) in Yosemite Valley. For a complete list of the birds counted this year, see the table below which is in phylogenic order.
