Description

Habitat

Ecology: Behaviour This species is mostly sedentary25. It shows some movements in response to rains13, which cause seasonal variation in habitat conditions24. However the movements are in general poorly understood. It occurs year-round in some areas (such as Zambia) where it is not known to breed24,26. Occasional records from Malawi, Zimbabwe, Mozambique and South Africa indicate that the species has a tendency to vagrancy25,26. Breeding appears to be irregular, but most often occurs during the months of March to June, coinciding with high flood-levels5,9,22. It breeds in small colonies of 1-60 nests , and usually forages in small groups of 4-8 individuals27, although it may forage solitarily or occasionally in larger aggregations of up to 60 individuals24,26. Habitat It inhabits river floodplains , marshes, and temporary shallow wetlands, preferring areas where water levels are receding from their seasonal peak26,27,28. It tends to avoid open water26, being most often found in areas where there is ample cover of short, emergent vegetation3,8 such as Cynodon dactylon and Panicum repens13. The availability of this habitat is increased by fire and high grazing pressure , however there has so far been insufficient data to confirm important links between these factors and the species's abundance , although it has been observed to be more abundant on burnt floodplains, and it often occurs in association with Red Lechwe Kobus leche13. It forages in water less than 10cm in depth26. Breeding It breeds in temporary wetlands at the time of - or shortly after - maximum water levels26. Its preferred breeding habitat is Phragmites reedbed13, but it will also nest on islands of vegetation such as water figs Ficus verruculosa, Acacia species13,16 and date (Tsaro) palms Phoenix reclinata12,17 . Diet When possible it feeds mainly on young fish3,29, especially cichlids20, but in temporary wetlands where fish do not occur, its diet consists of frogs , aquatic invertebrates13,20 and tadpoles2024,26,29. It locates prey by sight in clear, shallow water13,20. Additionally it will glean snails from lily pads and uses 'standing flycatching' to catch dragonflies and other insects26,29. It is thought to feed almost exclusively on fish except. It forages diurnally, often in association with other heron and wader species26. Breeding Site The nest is a bowl lined with fine plant material17, usually on a platform constructed from sticks , and the species shows high nest-site fidelity13. Clutch-size has been recorded as 1-4 eggs , with a mean of 2.4 (n = 16)13,17 , and the incubation period in one nest was recorded as 22-24 days18.
