The Knysna Scrub Warbler Bradypterus sylvaticus is a very cryptic warbler, endemic to South Africa. Population small and probably declining. Has a distinctive call which can be used to call it into sight with. A small population of about 40 pairs exists on the eastern slopes of Table Mountain, Cape Town. Most breeding territories are in dense vegetation along streams. Nests very close to the ground. Possibly highly philopatric - one of three colour-ringed nestlings was seen a year later occupying its parent territory. May undertake local migration.
