Population trends and environmental contaminants in herons in the Tennessee Valley, 1980-81 Population trends and environmental contaminants in herons in the Tennessee Valley, 1980-81
Great Blue Heron (Ardea herodias) eggs (N = 40) collected in 1980 from four of the largest colonies in the Tennessee Valley contained organochlorine pesticide, polychlorinated biphenyl (PCB), and chromium concentrations below those associated with reduced productivity. Low concentrations of organochlorine pesticide and PCB residues also were found in eggs (N = 31) from three of the...

Organochlorine pesticide residues in moths from the Baltimore, MD-Washington, D.C. area Organochlorine pesticide residues in moths from the Baltimore, MD-Washington, D.C. area
Moths were collected with a light trap from 15 sites in the Baltimore, Maryland-Washington, D.C. area and analyzed for organochlorine pesticide residues. On the average, the species sampled contained 0.33 ppm heptachlor-chlordane compounds, 0.25 ppm DDE, and 0.11 ppm dieldrin. There were large differences in the concentrations detected in different species. Concentrations were especially...

DDE in birds: Lethal residues and loss rates DDE in birds: Lethal residues and loss rates
Lethal brain residues of DDE2 were determined experimentally in four species of wild birds given dietary dosage of 1,500 ppm DDE until one-half had died, then sacrificing the survivors, chemically analyzing the tissues, and comparing results in dead birds and survivors. In all species, residues of 300 to 400 ppm of DDE in the brain were considered to show increasing likelihood of death...

Breeding biology of the blue-gray noddy Breeding biology of the blue-gray noddy
Blue-gray Noddies, the smallest marine terns, are similar in many respects to all tropical terns in Hawaii: single-egg clutches are laid, growth and development take about 7 weeks, breeding is colonial. Its small size results in eggs that comprise over 27% of adult body weight, compared to 15-20% for most marine terns (Langham 1983). Blue-gray Noddies are widespread in the tropical...

Methyl parathion and fenvalerate toxicity in American kestrels: Acute physiological responses and effects of cold Methyl parathion and fenvalerate toxicity in American kestrels: Acute physiological responses and effects of cold
Physiological and toxicological effects of p.o. methyl parathion (0.375-3.0 mg/kg) or fenvalerate (1000-4000 mg/kg) were examined over a 10-h period in American kestrels (Falco sparverius) maintained in thermoneutral (22?C) and cold (-5?C) environments. Methyl parathion was highly toxic (estimated median lethal dose of 3.08 mg/kg, 95% confidence limits of 2.29 -4.14 mg/kg), producing...

Annual variation in the distribution, abundance, and habitat response of the palila (Loxioides bailleui) Annual variation in the distribution, abundance, and habitat response of the palila (Loxioides bailleui)
We studied the distribution, population size, and habitat response of the Palila (Loxioides bailleui) during the 1980-1984 nonbreeding seasons to infer factors that limit the population and to develop management strategies. Distribution was fairly constant from year to year. Palila were confined to the subalpine woodland on Mauna Kea on the island of Hawaii, occurred between 2,000 and 2...
