Leech parasitism of waterfowl in North America Leech parasitism of waterfowl in North America
Leech parasitism of waterfowl is widespread in North America. Twenty species of ducks, geese, and swans have been infested by leeches, particularly Theromyzon rude and Placobdella ornata. Sites of attachment include the eyes, nasal passages, and body. Information is lacking on the biology and ecology of duck leeches. Their significance as morbidity and mortality factors and their...

Post-breeding activities of mallards and wood ducks in north-central Minnesota Post-breeding activities of mallards and wood ducks in north-central Minnesota
We used radio telemetry to monitor the post-breeding activities of 129 mallards (Anas platyrhynchos) and 118 wood ducks (Aix sponsa) on a 932-km2 area in north-central Minnesota from 1968 to 1974. Upon completion of breeding activities and before the flightless period, all mallard drakes departed the area; this exodus peaked during early June. Of the non-brood hens 8 of 23 remained on...

Duck nesting in intensively farmed areas of North Dakota Duck nesting in intensively farmed areas of North Dakota
A study to determine the major factors limiting duck nesting and production on intensively farmed areas in eastern North Dakota was conducted from 1969 through 1974. A total of 186 duck nests was found during searches on 6,018 ha of upland. Nest density per km2 for 5 major habitat types was 20.2 in untilled upland, 3.7 in standing grain stubble, 1.6 in mulched grain stubble, 1.2 in...

Analysis and machine mapping of the distribution of band recoveries Analysis and machine mapping of the distribution of band recoveries
A method of calculating distance and bearing from banding site to recovery location based on the solution of a spherical triangle is presented. X and Y distances on an ordinate grid were applied to computer plotting of recoveries on a map. The advantages and disadvantages of tables of recoveries by State or degree block, axial lines, and distance of recovery from banding site for...

Some Bayesian statistical techniques useful in estimating frequency and density Some Bayesian statistical techniques useful in estimating frequency and density
This paper presents some elementary applications of Bayesian statistics to problems faced by wildlife biologists. Bayesian confidence limits for frequency of occurrence are shown to be generally superior to classical confidence limits. Population density can be estimated from frequency data if the species is sparsely distributed relative to the size of the sample plot. For other...

Report of the American Ornithologists' Union Committee on Conservation, 1976-77. The recovery team-recovery plan approach to conservation of endangered species; A status summary and appraisal Report of the American Ornithologists' Union Committee on Conservation, 1976-77. The recovery team-recovery plan approach to conservation of endangered species; A status summary and appraisal
The U.S. Endangered Species Act of 1973 (P.L. 93-205) identifies the U.S. Fish and Wildlife Service (USFWS), under authority delegated by the Secretary of the Interior, as the lead agency charged with the conservation of most endangered species in the United States. Some marine species are the responsibility of the Secretary of Commerce, and the responsibility for marine turtles is...
