Late summer food habits of three heron species in northeastern Louisiana Late summer food habits of three heron species in northeastern Louisiana
Yellow-crowned Night-Herons (Nycticorax violaceus), Little Blue Herons (Egretta caerulea), and Green-backed Herons (Butorides striatus) collected in northeastern Louisiana from July-September 1980 exhibited different diets. Yellow-crowned Night-Herons fed mostly on crayfish (74% by weight) and Green-backed Herons fed primarily on fish (93% by weight). The diet of Little Blue Herons was...

Survival of female black ducks, Anas rubripes, during the breeding season Survival of female black ducks, Anas rubripes, during the breeding season
The Mayfield method was used to estimate the survival rate of 19 radio-marked, female Black Ducks (Anas rubripes) in southcentral Maine during 1977-80. An overall survival rate of 0.74 was estimated for the 121-day monitoring period that included the pre-laying and laying, incubation, brood rearing, and post-rearing stages. No differences in survival rates were detected among these...

Nest site characteristics of three coexisting Accipiter hawks in northeastern Oregon Nest site characteristics of three coexisting Accipiter hawks in northeastern Oregon
Habitat data were evaluated at 34 Goshawk (Accipiter gentilis), 31 Cooper's Hawk (A. cooperii), and 15 Sharp-shinned Hawk (A. striatus) nest sites in coniferous forests of northeastern Oregon. Crown volume profiles indicate a strong similarity in vegetative structure at nest sites of cooperii and striatus; both commonly nest in younger successional stands than gentilis. Habitat...

Impacts of forest herbicides on wildlife: Toxicity and habitat alteration Impacts of forest herbicides on wildlife: Toxicity and habitat alteration
This paper begins with a review of both laboratory and field studies on tbe possible direct toxic effects of herbicides on terrestrial vertebrates, primarily birds and mammals. Alteration of the palatability of forage and changes in reproductive success are also discussed. Emphasis is placed on the use of herbicides in forestry; studies dealing with agricultural systems are referenced...

Response of American black ducks to dietary uranium: A proposed substitute for lead shot Response of American black ducks to dietary uranium: A proposed substitute for lead shot
Lead (Pb) shot has been associated with mortality in waterfowl (Trainer and Hunt 1965, Anderson 1975, Stout and Cornwell 1976) and other avian species (Benson et al. 1974, Kaiser et al. 1980, Pattee et al. 1981). Bellrose (1959) indicated that between 2 and 3% of waterfowl populations may be lost yearly to lead poisoning. Incidence of lead shot in waterfowl and estimates of mortality...

Residues of petroleum hydrocarbons in tissues of sea turtles exposed to the IXTOC I oil spill Residues of petroleum hydrocarbons in tissues of sea turtles exposed to the IXTOC I oil spill
Sea turtles found dead when the Ixtoc I oil spill reached Texas waters were necropsied and tissues were analyzed for residues of petroleum hydrocarbons. Two of the three turtles were in poor flesh, but had no apparent oil-caused lesions. There was evidence of oil in all tissues examined and indications that the exposure had been chronic. Comparisons with results of studies done on birds...

Eggshell thickness and DDE residue levels in vlulture eggs Eggshell thickness and DDE residue levels in vlulture eggs
Post-DDT (post-1947) eggshell thickness was examined in samples of Turkey Vulture, Black Vulture, and Crested Caracara eggs from several parts of the United States. Highly significant post-DDT decreases in eggshell thickness indices of at least 10 percent were found in Turkey Vulture eggs from California, Florida, and Texas and in Black Vulture eggs from Texas and Florida. Over one-third...
