Red-shouldered Hawk and Spring Woodpecker Survey
Ontario Ministry of Natural Resources
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.
