Big Sur Ornithology Lab long-term banding database

The Big Sur Ornithology Lab was founded in 1992 as a long-term monitoring station to study landbird population trends at a coastal riparian site in central California. Trends may pertain to, but not limited to, four demographic categories: 1) breeding adults, 2) total adults, 3) local hatching year birds, and 4) hatching year migrants. Preliminary results include capture rates from 1993 to 2001 declining significantly over time in adult breeding Warbling Vireos, and a nearly significant decline in hatching year Warbling Vireos. Capture rates of hatching year Wilson's Warblers increased and capture rates of adult Black-headed Grosbeaks declined
