Bewick's Wren
Occurred the most disproportionately in hexagons with elevation (hex. avg.) less than 421 ft. and April maximum temperature (hex. med.) less than 18� C. At higher elevations, more likely to be associated with higher annual precipitation and towns and cities. The logistic regression analysis showed positive or negative association with elevation (hex. avg.), the extent of public land, April minimum temperature (hex. avg.), May minimum temperature (hex. avg.), and- to a lesser degree-big sagebrush shrubland, ponderosa - white oak woodland, and April minimum temperature (hex. med.).
