Ferruginous Hawk
Occurred the most disproportionately in hexagons with April precipitation (hex. max.) of 17-25 mm and containing some public land. Slightly less likely in similarly dry areas where less the extent of public land. In wetter regions (April precipitation [hex. max.] of 25-86 mm), it is most likely to occur where annual precipitation is 303-431 mm and May precipitation (hex. min.) is 18-21 mm. The logistic regression analysis showed positive or negative association with elevation (hex. avg.), April precipitation (hex. avg.), May precipitation (hex. avg.), and the extent of public land.
