Description

Habitat

Ecology: Behaviour There is no evidence of migration in this species, but it is prone to long-distance wandering in search of suitable habitat8,9. It is usually seen alone, sometimes with other herons1. It breeds mainly in small groups of a few pairs in mixed species colonies but also solitarily1,11. Various independent observations suggest that nesting takes place year-round1,5,7. There are observations of grey heron Ardea cinerea and A. humbloti chicks occupying the same nests ; though there is no evidence of mixed pairings or hybridisation, and this interaction between the two species is not understood7. Habitat The species prefers coastal areas (including coral islets , mangroves , tidal mud flats and estuaries) 8,10 but also frequents freshwater lakes (particularly those that persist through the dry season and are in close proximity to other lakes7), rivers and, more rarely, rice-paddies8,10. It forages in clear, shallow waters1,10 and among floating vegetation10,11. Habitat suitability depends on water clarity , shoreline areas with shallow water and the availability of large fish7. Diet It feeds chiefly on medium to large fish (up to 20cm11) and crustaceans1,3. Breeding Site It nests in tree-tops or hollows in rocks, and has also been reported to nest on the ground8,9. Its clutch-size is three.
