The Bangwa forest warbler or Bangwa scrub warbler (Bradypterus bangwaensis) is a species of Old World warbler in the family Locustellidae. It is native to the Cameroonian Highlands forests.
It is threatened by habitat loss.
It does not migrate.[2] It is territorial.[2]
Description
[edit]It does not exhibit physical sexual dimorphism.[2]
Breeding
[edit]It breeds in October and November.[2]
Vocalization
[edit]The males' characteristic song consists of repeating the same pitch at increasing volume.[2] Females sometimes duet with them by singing at decreasing pitches.[2] Females are not known to sing solo.[2]
Bangwa forest warblers sing more frequently in wet than dry season; this difference is especially pronounced in males.[2] The actual amount of precipitation has no effect on amount of singing.[2]
Their peak of vocal activity is during the first hour after sunrise.[2] Males have a second peak of vocal activity 11 hours after sunrise, but females do not.[2]
The function of their vocalizations is unknown.[2]
