Recent wood stork mycteria americana populations trends in the usa

, : Recent wood stork mycteria americana populations trends in the usa. Wilson Bulletin 91(4): 512-523

Surveys of the resident population of wood storks in the southwestern USA showed that numbers of breeding adults declined 41% between 1960 and 1975. The decline has been sharp in the large south Florida colonies, while the number of birds breeding in a scatter of smaller colonies between central Florida and southeastern Georgia has remained stable or slightly increased. Reasons for the decline are discussed, including loss of colony sites, lack of protection at colonies and loss of an adequate food base. The single important factor responsible for the stork decline may be a loss of feeding habitats coupled with a reduction in fish biomass or food availability in remaining wetlands.
