Plain Language Summary
Researchers from Natural Resources Canada, Environment Canada and the Ontario Ministry of Natural Resources used automated recording devices and sound analysis software to search for Kirtland’s Warbler (Setophaga kirtlandii) in northeastern Ontario. Kirtland’s Warbler is one of Canada’s rarest songbirds, with only a handful of breeding records at Garrison Petawawa in eastern Ontario. However, it is suspected that the species may be expanding into northeastern Ontario from its core breeding range in Michigan. Surveys were conducted in 2012 at 38 locations in 3 Ontario Ministry of Natural Resources administrative districts (Chapleau, Sault Ste. Marie and Sudbury). A Kirtland’s Warbler was detected on recordings from one location in Sault Ste. Marie district, on a single date (June 6). The recording and analysis approach appears to be an effective method for detecting rare bird species across extensive areas of their potential range.
