BFS Bird List


Birds

NOTES:

Names: Common and scientific names conform to the “Checklist of North and Middle American Birds” from the American Ornithological Society.

Abundance/Season: Abundance and seasonal data were collected by Dr. Catherine McFadden, Vivian & D. Kenneth Baker Professor of Biology at Harvey Mudd College, who has conducted monthly bird surveys at the BFS since December 2000. These data have been supplemented by observations by other BFS students, researchers, and visitors for birds not seen during the regular surveys. The most recent and complete frequency data are available on eBird, which contains data from Prof. McFadden’s surveys as well as observations reported by others.

Conservation Status: Any birds that have been assigned special protection or conservation status by the U.S. Fish & Wildlife Service or the California Department of Fish and Wildlife are indicated. Note that special status typically refers to nesting birds, rookeries, etc. and may not apply to some species at the BFS. Refer to the agency lists for details.

Photos and descriptions: Links labeled ‘BFS’, ‘AAB’ and ‘CP’ will direct you to the photos and/or descriptions of that species in the BFS Photo Database, ‘All About Birds’, and ‘CalPhotos’, respectively. Permissions policies for use of the linked photos are:

  • BFS: Photos on the BFS pages may be used for any personal or academic purposes as long as notification of use is sent to the BFS Webmaster and the image is clearly credited with ©[Name of photographer]. For higher-resolution images, please contact the photographer. No photos taken at the BFS may be used for commercial purposes without the express permission of The Claremont Colleges Services.
  • AAB: NO photographs may be downloaded, copied, archived, modified, or used for any reason, including posting on personal or other web sites, without permission of the photographer.
  • CP: Thumbnails may be used as long as they are properly credited. Use guidelines for the large photos vary among photographers. Click the “View Details” link at the top of the large images for information.

Additional information:

  • ‘Birds of the World’ is a powerful research database that brings together deep, scholarly content from four celebrated works of ornithology with millions of bird observations from eBird and multimedia from the Macaulay Library into a single platform where biologists and birders can explore comprehensive life history information on birds. Institutional or individual subscription required. Claremont Colleges students and faculty can access “Birds of the World” through the Claremont Colleges Library.
