Winter Raptor Surveys
The Winter Raptor Survey [WRS] project, established in the winter of 2004-05, is designed to determine wintering populations of the various species of birds of prey throughout the state of Oregon, and parts of California, Idaho and Washington. Through a collection of preapproved survey routes, volunteers completing the once a month surveys from December through February will count the various species that they find and report their findings to the project coordinator.

We are grateful to the National Audubon Society and the Environmental Systems Research Institute for access to ArcGIS Online, used in the production of our WRS map products. We are also grateful to our volunteers who have planned and coordinated this project, observed and recorded raptor populations for over a decade, and created the map visualizations.
