Shoebill  (Balaeniceps rex)

Although widespread, the shoebill is considered uncommon, with a total world population estimated at 5,000-8,000 (10). The small population is declining due to habitat destruction and degradation, nest disturbance, increased hunting levels and capture for the bird trade. Fire and drought threaten habitat in Zambia, nests are trampled by large herbivores feeding in swamps, and there is some evidence for trapping and persecution. Conflict in Rwanda and the Democratic Republic of Congo has disrupted some protected areas (e.g. Akagera National Park) that support the species, and the proliferation of firearms has greatly facilitated hunting of this bird. Destruction of papyrus swamps by cattle and fire also endanger the shoebill in its stronghold, Sudan. The area of Sudd swamps of southern Sudan almost trebled between 1952 and 1980, but this habitat is now threatened by its potential further drainage to facilitate renewed prospective plans for the Jonglei Canal (6). The current status of shoebills in the Sudd is unclear.

International trade in the shoebill is limited by the species' listing on Appendix II of the Convention on International Trade in Endangered Species (CITES) (3). However, trade does still occur, and this certainly poses an unwelcome pressure to already-dwindling populations. Plans are underway to upgrade the shoebill to Appendix I of CITES, which would render all trade illegal (11). This bird occurs in a number of reserves, although some of these are inadequately protected or have been given up after political unrest (8). The key site in Tanzania, the Moyowosi/Kigosi/Ugalla complex has a population of a few hundred individuals, and part of the area was designated as the country's first Ramsar Site in 2000 (12). The key site in Zambia, Bangweulu Swamps, is also a Ramsar Site (11). The Ramsar Convention on Wetlands is an international treaty for the conservation and sustainable utilization of wetlands, which aims to stem the progressive encroachment on and loss of wetlands, recognizing their fundamental ecological, economic, cultural, scientific, and recreational value (13). Uganda attaches economic value to the shoebill, which is an important asset for ecotourism in the country (11). A few injured birds are generally housed at the Kampala Zoo, some of which were confiscated from trappers and fisherman by the government (14). It has been suggested that a future priority for this bird might be to create community-based environmental awareness programmes focussed on generating national pride in the shoebill to discourage hunting (6). Indeed, recognition of the shoebill as one of the great African species can only serve to aid conservation efforts to save this unusual and cherished bird (5). It is also a priority to determine its current status in the extensive swamps and floodplains of southern Sudan, and to put an end to the live trade of this globally threatened species (11).
