Shorebirds in Celebes

Shorebirds in Celebes
In addition to four species of resident shorebirds, at least 34 migratory species visit Celebes coasts twice each year. They can be seen between February and april and between September and November, on their way to and from their breeding grounds in northeastern and eastern asia and their wintering grounds possibly in northwestern Australia (white 1975). Between February and april and returns between September and November. These birds would most often be encountered on muddy rather than sandy shores.

Very little is known about the movements of these birds within Indonesia and the basic questions posed thirty years ago have barely begun to be answered. That is: what are the normal migration routes? How many birds are there (commons de ruiter 1954)? Ornithologist from interwader, an international shorebird study programme, during the first part of 1986, and two areas of mudflat were visited: the north of bone bay, and the coast north and south of watampone.

The northern site had extensive mangroves but the mud was rather sandy and, therefore, not especially suitable for waders. One exception was the muddy estuary of the balease river where at least 18 species were seen, four of which constituted about half of the total number of birds seen. The coasts around watampone were found to have less sand than in the north, and the shorebirds were consequently more common though of fewer species (Uttley 1986).

Birds Wallacea Line

Birds Wallacea Line

There are 332 species of birds known from Celebes of which 92 (27%) are endemic, and 81 (25%) are migratory (White 1974, 1976, 1977; White and Bruce 1986). Nrecords of species not previously known from Celebes are still being made (Escott and Holmes 1980; Watling 1983) among the resident birds, 17 genera are endemic to Celebes and its surrounding islands including a large number of spectacular endemic birds such as the dark green bee-eater (Meropogon forsteni), the large brightly coloured hornbill (Rhyticeros cassidix), the crowned myna (Basilornis celebensis), and the finch-billed starling (Scissirostrum dubium) which nests in huge numbers in holes bored out of tall dead trees. Celebes best-known bird is the maleo (Macrocephalon maleo) which incubates its egg in pits that the adult birds dig.
