Formerly part of the Sage Sparrow complex of four subspecies, the Sagebrush Sparrow has been split off by the American Ornithological Union as a separate species and the remaining three subspecies are now grouped and renamed as Bell’s Sparrow A. belli.
The Savannah Sparrow (SASP) is 5.5" long with a 6.75" wingspan. The genus name Passerculus is from the Latin meaning little sparrow. The species name sandwichensis is Latin, of place, Sandwich, Unalaska, or Aleutians area, from which came the first subspecies, Aleutian Savannah Sparrow, to be described.
The genus name Passerella (pass-er-EL-ah) is from Latin, passer, meaning a sparrow. The species name iliaca (eye-lih-AY-cah) is Latin relating to the marked flanks. The common name is from the reddish or tawny “fox” color of feathers. The Fox Sparrow (FOSP) is about 7” long with a wingspan of 10.5” and a weight of 1.1 oz. (32g). It is one of our largest sparrows.
