Organochlorine residues in young herons from the upper Mississippi River-1976 Organochlorine residues in young herons from the upper Mississippi River-1976
Chicks of great blue herons (Ardea herodias) from four heronaries located near South St. Paul, Royalton, and Wabasha, Minnesota, and La Crosse, Wisconsin, were analyzed for organochlorines, Highest mean wet-weight concentrations, 6.43 ppm PCBs. 1.31 ppm DDE, and 1.90 ppm sigma DDT, were found in the South St. Paul chicks. Among chicks from the other three heronries, most levels were...

Multiple-factor influences upon feeding flight rates at wading bird colonies (Alias: Are flight-line counts useful?) Multiple-factor influences upon feeding flight rates at wading bird colonies (Alias: Are flight-line counts useful?)
The temporal patterns of feeding, resting, and reproductive behavior in colonial wading birds have been studied by a number of investigators (Recher and Recher 1972, King 1974, Capen 1978, Custer and Osborn 1978, Kushlan 1978) both on a short-term (daily) and long-term (annual) basis. In coastal marine environments, activities at colonies are influenced by tides (Recher and Recher 1972...

Mercury residues in tissues of dead and surviving birds fed methylmercury Mercury residues in tissues of dead and surviving birds fed methylmercury
Concentrations of mercury in passerine birds fed diets containing 40 ppm methylmercury were similar in tissues of birds that died from mercury poisoning and in those that were sacrificed after half the group had died. Residues were higher in tissues of birds that died, but the differences were not statistically significant. Residue levels were highest in livers, followed by kidneys and...

Acute oral and percutaneous toxicity of pesticides to mallards: Correlations with mammalian toxicity data Acute oral and percutaneous toxicity of pesticides to mallards: Correlations with mammalian toxicity data
Acute oral (po) and 24-hr percutaneous (perc) LD50 values for 21 common pesticides (19 anticholinesterases, of which 18 were organophosphates, and one was a carbamate; one was an organochlorine central nervous system stimulant; and one was an organonitrogen pneumotoxicant) were determined in mallards (Anas platyrhynchos). Three of the pesticides tested were more toxic percutaneously than...

Effects of sevin-4-oil, dimilin, and orthene on forest birds in northeastern Oregon Effects of sevin-4-oil, dimilin, and orthene on forest birds in northeastern Oregon
The possible harmful effect of insecticides on nontarget organisms should be a prominent concern in all attempts to control forest pests. Although all wildlife must be considered, birds are particularly vulnerable. The study reported here was part of the effort to find an environmentally safe method to control one of the major sources of insect damage to forest trees - the Douglas-fir...

Experimental lead poisoning in bald eagles Experimental lead poisoning in bald eagles
Captive, crippled bald eagles unsuitable for release were fed lead shot to determine diagnostic criteria for lead poisoning. The eagles were fluoroscoped and bled periodically to determine shot retention and blood delta--aminolevulinic acid dehydratase activity. Microscopic examination revealed renal tubular degeneration, arterial fibrinoid necrosis and myocardial necrosis. Acid-fast...

Effects of heptachlor-treated cereal grains on Canada geese in the Columbia Basin Effects of heptachlor-treated cereal grains on Canada geese in the Columbia Basin
In 1976 and 1977, die-offs of birds of several species occurred in Umatilla and Morrow counties, Oregon. Detection of high levels of heptachlor epoxide (HE) in tissues of Canada geese (Branta canadensis) prompted this study to determine the extent and impact of heptachlor contamination on geese on two study areas on the Columbia River--the Umatilla National Wildlife Refuge (Umatilla) in...
