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.

Metadata (Data about data or how the map was made)


This species is a locally uncommon colonial breeder in freshwater ponds and wetlands in the Columbia Basin notably the Potholes area, Lake Lenore, southeastern Yakima County, and Rearden.

Good habitat in the core areas of use included all freshwater bodies and wetlands in the Central Arid Steppe, Big Sage/Fescue, Wheatgrass/Fescue, and Three-tip Sage zones, but was limited to the areas with known breeding colonies.

Prior to 1973, the Black-necked Stilt was not known to breed in Washington. The first record for Washington was an individual collected on May 27, 1928 near Satus. The second and third records were a pair collected at Rearden on May 8, 1960. A pair in 1973 in Grant County provided the first nesting record for Washington followed by five more pairs in 1977. According to some, these initial records corresponded with dry years in southwestern states, which forced the stilts north to Washington where they have been established locally.
