Movements and survival of American black duck and mallard broods on Chesapeake Bay Movements and survival of American black duck and mallard broods on Chesapeake Bay
We attached radio transmitters to day-old American black duck (Anas rubripes) and mallard (A. platyrhynchos) ducklings and monitored duckling habitat use, brood movements, and survival rates for 30 days. Ducklings moved an average of 2.3 km within the first 24 hours and another 1.5 km thereafter. After the initial move, broods usually moved once more. No differences in initial movement...

Estimates of movement and site fidelity using mark-resight data of wintering Canada geese Estimates of movement and site fidelity using mark-resight data of wintering Canada geese
Population ecologists have devoted disproportionate attention to the estimation and study of birth and death rates and far less effort to rates of movement. Movement and fidelity to wintering areas have important ecological and evolutionary implications for avian populations. Previous inferences about movement among and fidelity to wintering areas have been restricted by limitations of...

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...

Survival and band recovery rates of sympatric grey ducks and mallards in New Zealand Survival and band recovery rates of sympatric grey ducks and mallards in New Zealand
We used band recovery data from grey ducks (Anas superciliosa) and mallards. (A. platyrhynchos) banded sympatrically during 1957-74 to estimate annual survival and recovery rates. Young birds tended to have higher recovery rates and lower survival rates than adults for both species. Both species showed strong evidence of year-to-year variation in annual survival rates. Survival rates of...
