Abstract:

Birds have been widely recognized as valuable indicators of environmental condition; and horned larks (Eremophila alpestris), Cassin's sparrows (Aimophila cassinii), lark sparrows (Chondestes grammacus), and grasshopper sparrows (Ammodramus savannarum) are abundant summer birds in the semidesert grasslands of southeastern Arizona. The authors compared densities and habitats of these species on grazed vs. ungrazed sites.
