Sequoia and Kings Canyon National Park Birds

Sequoia and Kings Canyon National Parks' 863,741 acres provide habitat for over 200 species of birds, including many neotropical migrants. Park biologists monitor birds to obtain more information about individual species and also because they are indicator species of local and regional change for the larger ecosystem. Documented effects of DDT on peregrine falcons and brown-headed cowbird nest parasitism on songbirds have alerted us to the dangers of pesticides and over-development. In the Sierra Nevada, these factors are implicated in the precipitous decline of the willow flycatcher.

Several monitoring programs are currently underway. Park staff record peregrine falcon activity on an annual basis, the Sequoia National Forest conducts annual California spotted owl surveys both adjacent to and within park boundaries, and in 2000, wildlife biologists coordinated the first annual SEKI Christmas Bird Count. In 1991 and 1992, the Institute for Bird Populations (IBP) operated two MAPS (Monitoring Avian Productivity and Survivorship) bird-banding stations in Kings Canyon. The parks have recently received funding to reestablish these stations. Park staff are seeking funds for a needed park-wide bird distribution and abundance survey. In 2000, the IBP completed an assessment of backcountry meadows in the parks to recommend which ones should be designated Important Bird Areas. In 1995 and 1996, baseline data were collected on brown-headed cowbirds - an obligatory nest parasite which drastically reduced the nesting success of host species and their numbers will be monitored in the future.

Sightings

In 2000, we recorded two rare sightings, a gyrfalcon and a great gray owl.

Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
