Project name: Birds Canada - Species at risk program

Goals : The primary objectives of the survey are to provide statistically reliable population trend data for Red-shouldered Hawks, Pileated Woodpeckers, and Yellow-bellied Sapsuckers and determine whether forest management practices are negatively affecting these species.

Year started : 1990

Year finished : 2006

Frequency : Annually

Primary species covered : Red-shouldered Hawks, Pileated Woodpeckers, and Yellow-bellied Sapsuckers

Field methods : Volunteers use tape playback to elicit calls of Red-shouldered Hawks along roadside routes at 20 predetermined stops during one morning in May. Volunteers keep track of the number of Red-shouldered Hawks that respond to the tape, as well as the number of other raptors and woodpeckers that they see or hear at each stop.
