Eggs from four species of aquatic birds inhabiting waterways of the Lake St. Clair region were collected in 1973 and analyzed for mercury. Species analyzed were mallard ducks (Anas platyrhynchos), common terns (Sterna hirundo), black-crowned night herons (Nycticorax nycticorax), and great egrets (Casmerodius albus). Mallard eggs contained relatively low residue...

Organochlorine residues in starlings (Sturnus vulgaris) from 126 collection sites were monitored during the fall of 1974. DDE, DDT, polychlorinated biphenyls (PCB's), and benzene hexachloride were present in all samples. Dieldrin, heptachlor expoxide, hexachlorobenzene, and oxychlordane were present in approximately 97% of the samples. DDE, dieldrin, and PCB residues in...

Organochlorine residues in wings of adult mallards and black ducks were monitored during the 1972-73 hunting season. DDE, DDT, DDD, dieldrin, and polychlorinated biphenyls (PCB's) were present in all samples. Mallard wings from Alabama contained the highest mean levels of DDE, DDT, DDD, dieldrin, and PCB's. Mallards and black ducks...

Clinal variation in the relative proportions of red and gray plum- age phases in Screech Owls (Otus asio) was analyzed by Owen (1963) and Marshall (1967). This variation was well known prior to Owen's work, but was misinterpreted (Baird, et al. 1874, Hasbrouck 1893, Allen 1893).]Laurel VanCamp and Charles Henny...

1. Eleven tissue systems from mallards and black ducks were examined for soluble proteins, lactate dehydrogenases and non-specific esterases through discontinuous polyacrylamide techniques.2. Biochemical relationships between the black duck and mallard are extremely similar.3. Hemoglobins and lactate dehydrogenase appear to be common in electrophoretic mobility between the two species.4. Approximately...

Beaver flowages and associated wetlands on the Chippewa National Forest, north-central Minnesota, were photographed from the ground and from the open side window of a small high-wing monoplane. The 35-mm High Speed Ektachrome transparencies obtained were used to map the cover-type associations visible on the aerial photographs. Nearly vertical aerial...

The literature contains numerous studies on Red-winged Blackbird (Agelaius phoeniceus) reproduction. Francis (1971) summarized eight studies dealing with nesting success. These and other studies have also provided information on breeding chronology, clutch sizes, sex ratios, survival rates for eggs and nestlings, reproductive physiology, and other life history aspects of reproduction....

Since publication of our report on the avian collections in the United States and Canada (Banks, Clench, and Barlow 1973, Auk 90: 136- 170) several changes and additions have come to our attention. In some cases, recent curatorial work has resulted in more accurate counts to replace previous estimates. Other...

Methylmercury dicyandiamide was fed to mallard ducks at 3 ppm mercury. Mercury accumulated in the eggs to an average of 7.18 and 5.46 ppm on a wet-weight basis in 2 successive years. Mercury in the eggs is believed to have caused brain lesions in the hatched ducklings. Lesions included demyelination,...

Seventeen white-tailed deer (Odocoileus virginianus) were radio-tagged in winter yards and tracked for up to 17 months each (881 locations) from January 1973 through August 1974 in the central Superior National Forest of NE Minnesota following a drastic decline in deer numbers. Ten vyolves (Canis lupus) from 7 packs in...

From 1966 through 1968, robins reproduced successfully in commercial apple orchards which were periodically sprayed with DDT, dieldrin, and other pesticides. Observations by a Z-man team using walkie-talkies revealed that breeding robins obtained essentially all food for themselves and nestlings from unsprayed areas adjacent to the orchards. Invertebrate trapping in...

Mallard ducks (Anas platyrhynchos) whose parents were fed a diet containing 0.5 ppm mercury (equal to about 0.1 ppm mercury in a natural diet) also were fed a diet containing 0.5 ppm mercury beginning at 9 days of age and continuing through their reproductive season. Mercury in the eggs of...

Mallard ducks (Anas platyrhynchos) were sacrificed one month after ingesting one number 4 all-lead shot or one number 4 lead-iron shot. Livers, kidneys, blood, wingbones, and eggs were analyzed for lead by atomic absorption. Necropsy of sacrificed ducks failed to reveal any of the tissue lesions usually associated with lead...

Lead concentration in blood and erythrocyte delta-aminolevulinic acid dehydratase (ALAD) activity was measured in mallard ducks dosed with one all-lead shot or one lead-iron combination shot. For 2 weeks after dosage, lead in blood of ducks given an all-lead shot was fourfold higher than in those dosed with lead-iron shot....

For 2 consecutive years mallard (Anas platyrhynchos) hens were fed a control diet or a diet that contained 0.5 or 3 ppm mercury as methylmercury (about 0.1 and 0.6 ppm mercury on the basis of a natural succulent diet). During the fifth egg-collection period, levels of mercury in eggs of...

Clearcut areas in northern Wisconsin aspen (Populus spp., mostly P. tremuloides) forests were highly attractive to woodcock (Philohela minor) for feeding and night-roosting, and made excellent sites for woodcock trapping and banding. Woodcock use of clearcuts was extended for several years by annually removing vegetation from trails with a...

This study was undertaken to document the timing of primary feather molt for aging purposes and to examine variability in rate of molt between years and between sexes of immature wild mourning doves (Zenaida macroura). We used capture records from a 7-year study on the Piedmont and Coastal Plain of...
