Birds

NOTES:

Names: Common and scientific names conform to the “Checklist of North and Middle American Birds”, 7th ed., including revisions through 2016 (57th Supplement), 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; however, 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 other BFS students, researchers, and visitors.

Conservation Status: Any birds that have been assigned special protection or conservation status by the U.S. Fish & Wildlife Service, the California Department of Fish and Wildlife, the North American Bird Conservation Initiative, or Partners in Flight 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’ ‘BNA’ and ‘CP’ will direct you to the photos and/or descriptions of that species in the BFS Photo Database, ‘All About Birds’, ‘Birds of North America’ (subscription required), and ‘CalPhotos’, respectively.
