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.

Has been thought possibly to be conspecific with T. melanops and T. tenebrosa. Race stictilaema moderately distinctive, with its greyer lower head sides, lightly streaked pale grey-buff vs plain whitish chin and upper throat, and slightly darker breast markings. Two subspecies recognized.

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

Gallery forest, thick clumps of riverine vegetation in open savanna woodland, swampside thickets, bamboo groves, tall scrub and rank grass along streams, parkland, sometimes mangroves; from sea-level in many areas, to c. 1000 m in Cameroon. In denser cover than that favoured by T. plebejus.

Movement

Resident.

Diet and Foraging

Insects and berries found in stomachs. Forages on ground among fallen leaves and debris under tangled vegetation, also among dead banana leaves, etc. Flips litter with bill. Found in small flocks of six or so, sometimes ten, individuals, even when breeding.

Sounds and Vocal Behavior

Chorus song involves accelerating and crescendoing single, scraping “jaaaaaaaa” or double “gwááá-ga” notes, raspy and chattering, punctuated with staccato “cha-ka-ta” or “ko-kwee”. Calls include continuous grating “ja-ja-ja-ja…” or lower, faster, almost trilling “jaagagagagaga”, used in contact; a loud braying, descending “waaa… haa-haa-haa-haa”; and various short harsh grating notes, e.g. “dzwit”, “dzwuk-dzwuk-dzwuk”, “jwiu”, “jut”.

Breeding

Nov–Dec in Gambia, Jan in Senegal, Sept–Jan in Sierra Leone and Nov–Jul in Mali; fledged dependent young in Jan in Ghana; Jun–Jul and Nov–Dec in Nigeria. Co-operative breeder. Nest a large open cup made of leaves, a few twigs and tendrils, scantily lined with roots and tendrils, placed 1·5 m or more up in head of small oil palm (Elaeis), palm-stump fronds or heavily foliaged tree. Clutch 2–3 eggs, dark sky-blue (much darker than blue variety of T. plebejus). No other information.
Not globally threatened. Uncommon to locally common across range. Fairly common and widespread in Gambia, S Senegal, Guinea-Bissau and Guinea, less so in Sierra Leone; widespread in Boucle du Baoulé National Park, in Mali; uncommon in Arli National Park, in Burkina Faso, but frequent around Ouagadougou; uncommon in Ivory Coast except in two areas, one being N Comoé National Park; fairly common and widespread yet patchy in Ghana; common in Togo. Presumed to be widespread in appropriate habitat in N Cameroon; fairly common in S Chad. Present in Dzanga-Ndoki National Park, in Central African Republic.
