Trumpeter swan The tundra swan ("C. columbianus") more closely resembles the trumpeter, but is significantly smaller. The neck of a male trumpeter may be twice as long as the neck of a tundra swan. The tundra swan can be further distinguished by its yellow lores. However, some trumpeter swans have yellow lores; many of these individuals appear to be leucistic and have paler legs than typical trumpeters. Distinguishing tundra and trumpeter swans from a distance (when size is harder to gauge) can be challenging without direct comparison but it is possible thanks to the trumpeter's obviously longer neck (the great length of
Pale-winged trumpeter Pale-winged trumpeter The pale-winged trumpeter ("Psophia leucoptera"), also known as the white-winged trumpeter, is a species of bird in the family Psophiidae. It is found in the southwestern Amazon rainforest of Brazil, northern Bolivia, and eastern Peru. It has two subspecies: The widespread nominate has a white rump and is found south of the Amazon River and west of the Madeira River, while "ochroptera" has a yellowish rump and is found between the Amazon River and the lower Rio Negro. Genetic evidence suggests the closest relative of "ochroptera" is the grey-winged trumpeter, leading some to treat it as a separate
