CHAPTER 3 - DIGITAL ATLAS OF COLONIES OF SEVEN SPECIES OF INLAND-BREEDING WATERBIRDS IN CALIFORNIA
The tables included here to accompany the digital site maps and species maps present data on estimated numbers of seven breeding colonial waterbirds from statewide surveys of the interior of California from 1997 to 1999 (1994–1997 for gulls), with some supplemental data collected in 2000 and 2001. Although the surveys covered seven species, no table is included for the American White Pelican because the limited data for that species during the survey period are included in the text of the companion report. Still, there are eight tables: Double-crested Cormorant (1), Ring-billed and California gulls (1), Caspian Tern (1), Black Tern (3), and Forster's Tern (2). These tables are a subset of the 19 tables included in the companion report, the rest of which present long-term data on the numbers of adults, pairs, nests, or young of particular species at various sites or areas in the interior of California. Additional historical data on these species are included within the text and appendices of the companion report.
Clicking on the species or species groups' names will reveal the pdf tables for these taxa. Users are cautioned not to use or interpret these data without first reading the overview text and relevant species accounts in the accompanying report.
