Bald eagle and osprey Bald eagle and osprey

Bald eagles nested in all nine western states during recent years (about 19% of known U.S. population in 1982). The known numbers of nesting pairs in the west increased substantially in the last 10 years and totaled 584 in 1986. Much of the increase was due to more intensive survey efforts, but most biologists cite examples of new palrs establishing nesting territories. In contrast...

Telemetry location error in a forested habitat Telemetry location error in a forested habitat

The error associated with locations estimated by radio-telemetry triangulation can be large and variable in a hardwood forest. We assessed the magnitude and cause of telemetry location errors in a mature hardwood forest by using a 4-element Yagi antenna and compass bearings toward four transmitters, from 21 receiving sites. The distance error from the azimuth intersection to known...

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...

Predator-prey interactions, resource depression and patch revisitation Predator-prey interactions, resource depression and patch revisitation

Generalist predators may be confronted by different types of prey in different patches: sedentary and conspicuous, cryptic (with or without refugia), conspicuous and nonsocial, or conspicuous and social. I argue that, where encounter rates with prey are of most importance, patch revisitation should be a profitable tactic where prey have short 'recovery' times (conspicuous, nonsocial prey...
