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 :
Year finished :
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.
