358 Muscicapidae: flycatchers and batises

Mozambique 14û Mosambiekbosbontrokkie BATIS Batis soror 1 5 The Mozambique Batis inhabits the coastal belt 18û of Mozambique and extends to just south of the equator. It occurs marginally in the eastern high- lands of where it is reported infre- quently. 22û It was formerly considered to be a subspecies 6 of the Chinspot Batis B. molitor and it closely 2 resembles that species in appearance (especially the males) and vocalizations. It is inconspicuous 26û when not calling, because it tends to remain in the tree canopy. Its habitat in Zimbabwe is the wood- land of the moist seaward-facing slopes of the 3 7 mountains from Nyanga (1832BA) southwards 30û to the Chimanimani area (1933C), and also the Save–Runde river confluence (2132AB) (Irwin 1981). It ascends to at least 1500 m in the Chi- 4 8 manimani Mountains (Irwin 1981). 34û Any movements are likely to be altitudinal. 18û 22û 26û Most atlas records come from summer, but there 10û 14û 30û 34û is insufficient information. Egglaying has been reported October–November (Irwin 1981). The Mozambique Batis is said to replace the Chinspot Batis in moister areas, and their overlap is probably mar- ginal and limited to areas with a wide range of altitudes, except at the Save–Runde confluence (Irwin 1981). In the Haroni–Rusitu (2032BB) area, those two species are sea- sonally also found with Cape B. capensis and Woodwards’ Recorded in 5 grid cells, 0.1% B. fratrum Batises, but again with some separation by habi- Total number of records: 37 tat and altitude (Irwin 1981).
