Field Identification

12 cm; 8–11 g. A localized grey apalis with distinctive white wingpanel and a relatively long bill. Nominate race is ash-grey above, with short, narrow whitish supercilium from base of bill to above eye; lores blackish, ear-coverts slightly darker grey than crown; tail dark grey, with white tips on T2, grading to fully white outer two rectrices; flight-feathers and greater upperwing-coverts dark grey, white outer webs of inner secondaries and tertials form obvious white panel on folded wing; whitish below, lightly washed grey on flanks, thighs mottled blackish; iris reddish-brown; bill black; legs reddish-brown. Sexes alike. Juvenile undescribed. Race stronachi male has darker, brown-washed upperparts, breast and flanks darker grey, female paler.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Racial identity of birds recently recorded in SW Kenya uncertain, tentatively included in race stronachi; study required. Two subspecies recognized.

Subspecies


SUBSPECIES

Apalis karamojae karamojae Scientific name definitions

Distribution

locally in NE Uganda (Kanatorok, in Kidepo Valley, and Mt Moroto, Mt Kamalinga and Mt Kadam).

SUBSPECIES

Apalis karamojae stronachi Scientific name definitions

Distribution

N Tanzania (Wembere Steppes, Serengeti (1) ) and SW Kenya (Kedong Valley, Masai Mara (2) ).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Acacias and other small trees and shrubs in semi-arid savannas; often along watercourses and in seasonally flooded areas.

Movement

Presumably mostly resident.

Diet and Foraging

No information on diet; presumably mainly insects. Occurs in pairs or in groups of up to six individuals. Forages by gleaning foliage and small branches of acacias and other shrubby vegetation.

Sounds and Vocal Behavior

Pair-members sing from perches 2–3 m up, near tops of acacia trees (Acacia), song an antiphonal duet comprising a series of fluid, musical phrases, each partner alternating notes, songs last 6–71 seconds, each bird giving 1·3–1·5 notes per second, resulting in combined duet at 2·7–3·2 notes per second; phrases cycled every 10–20 seconds during a song bout (atypical for an apalis); examples of phrases include “dway tow tee tow tee”, “wee way toi tuu”, “wee wee téé way”, “wee way wéé tuu”. Contact call a soft “we we we” or “dwe dwe dwe”; alarm a rasping “jirrrrr jirrrrr”. Fledged chicks beg with rapid “chit-chit-chit…”, accelerating to rasping call when parents deliver food.

Breeding

Pairs with fledged young observed in Jul in Tanzania. One nest and eggs found, but not formally described. No other information.

VULNERABLE. Restricted-range species: present in Serengeti Plains EBA and North-East Uganda Secondary Area. Appears to be scarce in NE Uganda, but is locally fairly common in N Tanzania, and recently discovered in SW Kenya (Kedong Valley); global population crudely estimated to be in excess of 10,000 individuals. Since 2000 the species became increasingly widespread in the Western Corridor of Serengeti National Park, which now appears to be its main Tanzanian stronghold (3). Decreasing, largely as a result of habitat loss linked to increasing agriculture in its very limited range. Populations are protected in Kidepo Valley National Park, in Uganda, and Serengeti National Park and Maswa Game Reserve, in Tanzania.
