GAP Analysis Predicted Distribution Map

Sage Sparrow (Amphispiza belli)

Species Code: AMBE

Legend:
= Core Habitat
= Marginal Habitat

Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

The Sage Sparrow is uncommon and declining in sagebrush landscapes of the Columbia Basin, limited by the presence of mature Big Sagebrush stands and hot, dry conditions. It is a possible breeder in the Methow valley, but rare as a breeder from the Okanogan valley. It is a rare and local visitor outside the mapped region. Some important breeding areas for Sage Sparrows include the Yakima Indian Reservation from Toppenish to Mabton (Yakima County).

Good habitat in core zones were grasslands (except those specifically identified as annual-dominated), shrub savanna, and shrublands in the Central Arid Steppe, Big Sage/Fescue, and Three-tip Sage zones of eastern Washington.

Washington breeders represent the northern subspecies A. b. nevadensis. Recent work may prove that A. b. nevadensis and A. b. belli (and possibly A. b. canescens) are distinct species. Sage Sparrows can be found in large tracts of sagebrush, yet seemingly suitable habitat is often lacking this species. Its exact habitat requirements remain a mystery. Sage Sparrows should represent a conservation concern in Washington.
