Geographic and temporal differences in band reporting rates for American black ducks Geographic and temporal differences in band reporting rates for American black ducks
Recoveries of reward- and standard-banded American black ducks (Anas rubripes) were used to estimate band reporting rates and to investigate geographic and temporal variability in reporting rate for 1978-80. Reporting rates were higher close ( 20 km) to the parent banding site in 3 of 42 samples and were higher close to the nearest black duck banding site in 3 of 35 samples., Reporting...

Tissue lead distribution and hematologic effects in American kestrels (Falco sparverius) fed biologically incorporated lead Tissue lead distribution and hematologic effects in American kestrels (Falco sparverius) fed biologically incorporated lead
American kestrels were fed a diet containing 0.5, 120, 212, and 448 ppm (dry wt) biologically incorporated lead (Pb) for 60 days. The diet consisted of homogenized 4-wk-old cockerels raised on feed mixed with and without lead. No kestrels died and weights did not differ among treatment groups. The control group (0.5 ppm Pb) had the lowest mean concentration of lead and the high dietary...

Disseminated visceral coccidiosis in sandhill cranes Disseminated visceral coccidiosis in sandhill cranes
Disseminated visceral coccidiosis (DVC) caused by Eimeria spp was first recognized as a disease entity in captive sandhill cranes (Grus canadensis) and whooping cranes (G americana) at the Patuxent Wildlife Research Center. Because cranes produced at the Center are reintroduced to the wild to augment wild populations, studies involving both experimentally induced and natural infections...

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...

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...

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...

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...
