GAP Analysis Predicted Distribution Map

Northern Waterthrush (Seiurus noveboracensis)

Species Code: SENO

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.

This waterthrush is locally uncommon in swampy wetlands and bogs of moist forests in northeastern Washington. Breeding is limited to Okanogan, Ferry, Stevens, Pend Oreille, and northern Spokane Counties.

All zones above steppe in northeastern Washington, plus small parts of the Ponderosa Pine and Interior Douglas-fir zones in the northern Okanogan valley were core. Water/wetlands and hardwood forests were good habitats; other forests and forest openings and clearings were contingently suitable, i.e. suitable if appropriate habitats (swampy wetlands and bogs in this case) occurred within the larger mapped habitat. In the Ponderosa Pine zone, forest openings and clearings were excluded.

Washington breeders represent the widespread western subspecies S.n.notabilis. The Northern Waterthrush is dependent on appropriate wet micro-habitats, such as swamps with alders or willows and standing water. Although not rare in northeastern Washington, no confirmed records were known as of 1953. Additionally,as of 1987, only one known nest from British Columbia's Okanagan valley was listed to that date. Evidence of breeding in Washington was first reported in the summer of l962 at Harvey Creek (Pend Oreille County), but few nests have been found since then.
