Flight restraint techniques for captive cranes Flight restraint techniques for captive cranes
Traditional techniques for preventing escape of captive cranes (i.e., tenotomy, tenectomy, wing clipping, confinement under nets, and amputation) are discussed briefly. Two additional techniques (i.e., brailing and vane trimming) are described in detail. The advantages and limitations of each technique are presented.

Freshwater molluscs as indicators of bioavailability and toxicity of metals in surface-water systems Freshwater molluscs as indicators of bioavailability and toxicity of metals in surface-water systems
During the past several decades, studies from a variety of locations have demonstrated widespread occurrence of metals in surface waters at concentrations significantly higher than background levels. Elevated concentrations are not limited to certain water types or polluted areas; they appear in all types of systems and in all geographic areas. It is clear that metals enter the aquatic...

Herons and egrets as proposed indicators of estuarine contamination in the United States Herons and egrets as proposed indicators of estuarine contamination in the United States
The National Contaminant Biomonitoring Program of the U.S. Fish and Wildlife Service Includes the sampling of freshwater fish, starlings, and duck wings. In order to include an estuarine component, herons and egrets are being evaluated. Organochlorine concentrations were measured In eggs and chicks of Snowy Egrets Egretta thula, Great Egrets Casmerodius albus, and Black-crowned Night...
