It is found in western central Africa. DescriptionThe Angola batis is a small pied songbird with a rather dumpy appearance and a restless nature. The adult males have a buish greyforehead and crown with a small white spot on the lores and a glossy black mask across the eyes, extending on to the nape and down the sides of the neck with a white spot on the nape. It has a grey mantle, blackish scapulars with the back, rump and uppertail covers being blackish grey with white spots. The wings have black flight feathers with narrow white edges. There is a white wing stripe. The trail is black with white outer tail feathers. The underparts are white except for a black band across the breast and the greyish undertail coverts. The eyes are bright yellow while the bill and legs are black. The female is similar to the male but her breast band is chestnut rather than black.[2] They are about 10 cm long and weigh 10.4g[3] VoiceThe calls of the Angola batis are little known, the territorial call is a series of high-pitched notes, "zee-zee-zee-zee-zee", which has been likened to a squeaky bicycle pump.[2] DistributionThe presence of the Angola batis in south eastern Gabon is yet to be confirmed but the species occurs in the southern Congo through western Democratic Republic of Congo into northern Angola south to the Quiçama National Park, 70 km from Luanda.[2] Habits and habitatThe habits of the Angola batis are little known, it feeds on insects which are often caught in the air by sallying from a perch, a behaviour called "flycatching". The appear to be rather solitary, like other batises, being recorded mainly as single or in pairs.[2] The cup shaped nest is built by both sexes from strips of bark and spider webs and is placed in the fork of a small tree at around head height. The only recorded cluches have consisted of 2 eggs. Breeding behaviour has been observed in the Democratic Republic of Congo in July.[3] The Angola batis occurs in secondary and riverine gallery forest, thick woodland dominated by Croton spp as well as adjacent bush, tickets and the ecotone between forest and savannah. Occasionally recorded in dry woodland, especially in the southern part of its range, as well as coffee plantations.[2] References1. ^{{cite web | url = http://www.iucnredlist.org/details/22707920/0 | title = Batis minulla |accessdate = 2013-11-03 | publisher = International Union for Conservation of Nature and Natural Resources|work = The IUCN Red List of Threatened Species}} {{Taxonbar|from=Q1308750}}{{DEFAULTSORT:batis, Angolan}}2. ^1 2 3 4 {{cite book | last1 = Harris | first1 = Tony | last2 = Franklin | first2 = Kim | year = 2000 | title = Shrikes and Bush-shrikes | publisher = Christopher Helm | pages = 315–316 | ISBN = 0-7136-3861-3}} 3. ^1 {{cite web | url = http://www.hbw.com/species/angola-batis-batis-minulla | title = Angola Batis (Batis minulla) | accessdate = 2016-11-03 | publisher = Lynx Edicions|work = Handbook of the Birds of the World Alive}} 4 : Batis (bird)|Birds of Central Africa|Birds described in 1874|Taxonomy articles created by Polbot |
