GAP Analysis Predicted Distribution Map

Trumpeter Swan (Cygnus buccinator)

Species Code: CYBU

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.

This species is currently limited to only one (apparently non-breeding) pair of birds at Turnbull National Wildlife Refuge.

No habitat was modeled.

Trumpeter Swans were first reintroduced to the Turnbull National Wildlife Refuge in 1963 when six cygnets were transferred from Montana. Prior to 1963, this species was very rare in Washington. There was one reported in mid-summer in Ferry County, but the report was without any details and the sighting was rebutted. At the Turnbull National Wildlife Refuge nesting was attempted in 1966 and successful from 1967 to 1969. After many years a pair was again noted in 1994, but with no breeding success to date. A single adult was seen June 17, 1991 at Calispell Lake, well away from the Turnbull site.
