Botteri's sparrow (Peucaea botterii) is a medium-sized sparrow. This passerine bird is primarily found in Mexico, with a breeding range that extends into the southeastern tip of the U.S. state of Arizona, and a small non-migratory population in the Rio Grande Valley of southern Texas, which is threatened by loss of habitat. It was not found in Arizona between the 1890s and the mid-20th century due to excessive grazing of livestock; now it is locally common in its Arizona range due to recovery of vegetation. Juvenile birds apparently need dense vegetation to hide in during fledging; the uncommon native sacaton grass Sporobolus wrightii is preferred, but stands of introduced non-native Lehmann lovegrass (Eragrostis lehmanniana) and Boer lovegrass (E. curvula var. conferta) are also successfully utilized, though at lower population densities. The name of this species commemorates the ornithologist Matteo Botteri (1808–1877). References Further reading Book Webb, E. A., and C. E. Bock. 1996. Botteri’s Sparrow (Aimophila botterii).
