A new report from the American Bird Conservancy documents the first ever multi-State review of feral cat impacts on birds. Titled Impacts of Feral and Free-Ranging Cats on Bird Species of Conservation Concern: A five-State Review of New York, New Jersey, Florida, California and Hawaii, by Linda Winter, the report analyzes the negative effects that cats are having on some of America's most at-risk bird species at cat predation hotspots. The report is available for download and printing from ABC's web site, www.abcbirds.org/cats/NFWF.pdf.

The Hawaii report is particularly of interest to me because it includes the petrel which I discovered and reported at Haleakala Crater, Maui, in 1951 (The Elepaio, Hawaii Audubon Society 12:31-33) and verified by Frank Richardson in 1954 to be the Dark-rumped Petrel (Condor 56:323-327), now called the Hawaiian Petrel, and federally endangered.
