Nesting phenology and success of ring-necked ducks in east-central Maine Nesting phenology and success of ring-necked ducks in east-central Maine
Selected aspects of the nesting biology of Ring-necked Ducks in east-central Maine were studied during 1983-1985 and compared to previous studies. Nesting chronology, clutch size, and hatching success were similar to results reported from previous studies, but nest success was 32-42% lower. Thirty-eight percent of the nests were successful; % of the eggs in successful nests hatched...

The shiny cowbird Molothrus bonariensis in the West Indian region--Biogeographical and ecological implications The shiny cowbird Molothrus bonariensis in the West Indian region--Biogeographical and ecological implications
The shiny cowbird (Molthrus bonariensis), an avian brood parasite, is endemic to South America, Trinidad, and Tobago, but during the last 100 years the species has spread through the West Indies. Successful colonization by the shiny cowbird depends on the availablitiy of suitable habitats and host species. As forest fragmentation increases in the West Indies, new hosts, particularly...

A coded tracking telemetry system A coded tracking telemetry system
We describe the general characteristics of an automated radio telemetry system designed to operate for prolonged periods on a single frequency. Each transmitter sends a unique coded signal to a receiving system that encodes and records only the appropriater, pre-programmed codes. A record of the time of each reception is stored on diskettes in a micro-computer. This system enables...

Food habits and organochlorine contaminants in the diet of olivaceous cormorants in Galveston Bay, Texas Food habits and organochlorine contaminants in the diet of olivaceous cormorants in Galveston Bay, Texas
More than 1,000 food items, representing 32 species of fish and one invertebrate, were identified from olivaceous cormorants. Six species of fish comprised 79% of the diet by frequency of occurrence and 78% by weight. Almost half of the diet consisted of a single species, the sheepshead minnow. Concentrations of pp-dichlorodiphenyldichloroethylene (DDE) in cormorant carcasses were 27...
