This document is a supplement to the Phase I Avian Risk Assessment (Kerlinger 2003, revised 2005) and the Breeding Bird Survey (Kerlinger and Dowdell 2003) reports for the Deerfield Wind Project, formerly referred to as the Searsburg/Readsboro Expansion project. The original reports were completed in 2003, and this supplement is a means of bringing those two reports up to date. For the Phase I Avian Risk Assessment, this supplement includes:
- Updates regarding empirical studies of avian-related impacts at existing wind power sites in the United States and Canada;
- Updated information about whether night migrants follow ridges in the northeastern United States
- Information on whether FAA L-864 flashing red lights used at existing wind turbines attract or disorient night migrants, resulting in collisions; and
- Recent references regarding wind power impacts to birds.
For the Breeding Bird Survey, this supplement inlcudes reference to a study of Bicknell's nesting at the Deerfield project site by U.S. Forest Service biologists.
