Abstract

This research intends to know interaction type among three heron species while foraging around Pulau Dua Nature Reserve, SerangBanten's Province. Observational method that is utilized is direct observing up to 6 months, pictures taking supported watch utilizeHandycam by focal observation method, meanwhile data analyze was done by using scan sampling method. The research’s result points out that interaction during foraging for three species herons, namely Casmerodius albus, Egretta garzetta, and Bubulcus. Ibis, cover neutralism, competition and cooperation. C. albus showed cooperative's interaction as much as 66.67%. This interaction is happening between C. albus and Phalacrocorax sp. The competition and neutralism on C. albus each of them are 16.67%. E. garzetta showed neutralism as much as 50%, between E. garzetta and other waterbird which are Threskiornis melanocephalus and Plegadis falcinellus. Meanwhile, cooperative as high as 37.50% and competitions as high as 12.50%. B. ibis showed neutralism, as high as 44.44% between B. ibis and both Ardeola speciosa and P. falcinellus.

Abstract

This research is to know feeding location for three species herons that lived in Pulau Dua Nature Reserve (CAPD), Serang, Banten Province. This research has been done at feeding area for the herons around Pulau Dua Nature Reserve. The data were taken from film shooting use Focal Observation Methods, while the film shooting analysed use Scan Sampling Methods. Result showed that Casmerodius albus and Egretta garzetta were using the mudflat, fisheries and rice-fields around CAPD as feeding location. Bubulcus ibis was using ricefield and grassland as feeding location. The preference for C. albus to feeding in mudflat was (χ²=21691,29; db=2, α=0,01). E. garzetta have preference for feeding in fisheries (χ²=18221,27; db=2, α=0,01) and the preference for B. ibis to feeding in grassland is (χ²=27,57; db=1, α=0,01). The selections of feeding location for three species herons were depend on the specific preys for them. C. albus and E. garzetta were select fish as their food, and B. ibis choose insect and other small animals as his food. © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: feeding, location, herons, mudflat, rice-field, grass-land, fisheries.

One species from Ciconidae Family, Scolopacidae Family, and Ploceidae Family. Thirteen species of them were protected in Indonesia; there were Egretta garzetta, E. sacra, Ardea cinerea, Ciconia episcopus, Larus ridibundus, L. brunnicephalus, Sterna sumatrana, S. dougallii, Anous minutus, Gygis alba, Halcyon pileata, Todirhamphus chloris, and Lonchura fuscans.
