Mrs. Moreau's Warbler Scepomycter winifredae Scientific name definitions

A medium-sized warbler associated with montane forest clearings, Mrs. Moreau's Warbler (or Winifred's Warbler) is endemic to Tanzania, where it is known only from the Uluguru Mountains, Ukaguru Mountains and Rubeho Mountains from 1,350‒2,430 m elevation. Birds from the Ukaguru and Rubeho Mountains are considered by some authorities to be a separate species, the Rubeho Warbler (Scepomycter rubehoensis), but this taxon is treated as subspecies rubehoensis here.

Almost nothing is known about the natural history of Mrs. Moreau's Warbler, even its nest and eggs have not been described. This species usually occurs in pairs and is most often detected by its loud and extraordinary duet song. It is difficult to observe as it moves among tall herbs, shrubs, and vine tangles in montane forest clearings. It appears to be specialized for inhabiting the dense successional vegetation that develops after the forest canopy is disturbed by logging or farming activity, landslides, treefalls, or foraging by African savanna elephant (Loxodonta africana).

Since Mrs. Moreau's Warbler occurs in only a few mountain areas in Tanzania and is suspected to have a small population (500–1,500 individuals) that is likely in decline owing to habitat loss and degradation, it has been listed as Near Threatened by BirdLife International.
