Cooper's Hawk
Occurred the most disproportionately in 3 different situations: (a) in hexagons with annual precipitation of 683-1134 mm and white oak forest present, (b) hexagons with annual precipitation of 431-683 mm and elevation (hex. avg.) of 237-604 ft., or (c) hexagons with annual precipitation of 1134-1511 mm and less than 12% mixed conifer forest (Douglas-fir dominant). The logistic regression analysis showed positive or negative association with ponderosa pine forest, big sagebrush shrubland, number of land cover types, June maximum temperature (hex. min.), and-to a lesser degree-July precipitation (hex. min.).
