American Crow
Occurred the most disproportionately in hexagons with elevation (hex.
avg.) less than 421 ft., or somewhat higher (421-1204 ft.) when there is
relatively little public. It occurred at higher average elevations (1204-
2002 ft.) if topographic variation is relatively great and June minimum
temperature (hex. max.) is 24-28� C. The logistic regression analysis
showed positive or negative association with agricultural lands,
elevation (hex. avg.), topographic variation, April minimum
temperature (hex. max.), May minimum temperature (hex. max.), July
minimum temperature (hex. avg.), the extent of public land, and-to a
lesser degree-April maximum temperature (hex. avg.) and April
maximum temperature (hex. max.).
