The Baltic Macoma: abundance and distribution of an important winter food of diving ducks in Chesapeake Bay The Baltic Macoma: abundance and distribution of an important winter food of diving ducks in Chesapeake Bay
Poor water quality and widespread depletion of wild celery (Vallisneria americana) and other submerged aquatic plants important as waterfowl foods has resulted in the continued dependence of canvasbacks (Aythya valisineria) on Baltic clams (Macoma balthica) as their primary winter food. Despite this dependence, no information exists regarding the distribution and abundance of Baltic...

Characteristics of some black duck nest sites in Maine Characteristics of some black duck nest sites in Maine
A standard method for characterizing nest sites and concealment (visibility of orange decoy and percent overhead cover measured by densiometer) was used to obtain characteristics of 36 nest sites of black ducks in Maine, 1978-89. Nest locations were represented by cutover areas (10), islands (6), bogmat (5), emergent meadow (5), emergent wetland (3), stream floodplain (3), hardwood...

Results of an experiment to lead cranes on migration behind motorized ground vehicles Results of an experiment to lead cranes on migration behind motorized ground vehicles
Ten greater sandhill cranes (Grus canadensis tabida), trained to enter and ride in a specially equipped truck, were transported at 80? days of age from their rearing site at Patuxent Wildlife Research Center (Patuxent), Maryland, to a reintroduction site located within the species? former breeding range in northern Arizona. After 5 additional weeks of training, these juvenile cranes were...

Contaminant concentrations and biomarker response in great blue heron eggs from 10 colonies on the upper Mississippi River, USA Contaminant concentrations and biomarker response in great blue heron eggs from 10 colonies on the upper Mississippi River, USA
In 1993, great blue heron (Ardea herodias; GBH) eggs were collected from 10 colonies on the upper Mississippi River (UMR). They were then artificially incubated until pipping and analyzed for mercury, selenium, and organochlorines. Livers of embryos were analyzed for hepatic microsomal ethoxyresorufin-O-dealkylase (EROD) activity and four measures of oxidative stress. Brains were...

Evaluation of semen from nondomestic birds Evaluation of semen from nondomestic birds
Aspects of poultry Al technology are applicable to nondomestic birds. However, modifications in the methods of semen collection, evaluation, and insemination are often necessary to accommodate either the bird's size, sperm numbers, or. female anatomy. This section provides a brief overview of procedures used to evaluate semen from nondomestic birds. Unless specified, materials, reagents...

Survival and fates of staging juvenile, female mallards in the Vermont / Quebec border region Survival and fates of staging juvenile, female mallards in the Vermont / Quebec border region
We alternately marked 80 juvenile, female mallards (Anas platyrhynchos), half with transmitters and bands and half with only bands in 1990 and 1991. Survival of radio-marked ducks was monitored daily and then summarized weekly for the periods 31 August - 6 December, 1990 (weeks 5-18) and 11 September - 6 December, 1991) (weeks 6-18). The pattern of survival throughout the staging period...
