The Bamenda Apalis Apalis barnendae is a species endemic to Cameroon which, prior to this study, was known from only eight sites in the Bamenda Highlands and the Adamawa plateau. It is a restricted range species and its global status is considered Vulnerable. Because this species was very poorly known and of conservation concern, surveys were undertaken on the Adamawa Plateau and in the Bamenda Highlands from April-June 1999 and January-April 2000. As a result, the Bamenda Apalis is now known to occur at more than 70 sites and 115 sightings were made. The range of the species is much wider than previously thought and extends well into the Adamawa plateau and most probably as far as the Yade Hills in the Central African Republic. Its altitudinal range, from 700 m to 2050 m, is typical of a paramontane species. This Apalis clearly favours gallery forests where, within its range, it is rather common. The species shows very little or no overlap with Buff-throated Apalis Apalis rufogularis, which bamendae seems to replace outside larger forest blocks situated at lower altitudes. At a higher altitude, it is replaced by Black-collared Apalis Apalis pulchra and Grey Apalis A. cinerea. It is recommended to downgrade the IUCN conservation status of Apalis bamendae from 'Vulnerable' to 'Least Concern', based on the following facts: the species is found over a wide range (over 80 000 km); it is common in suitable habitat; it is now found in protected areas and, critically, it can adapt to degraded habitats.
