Sexual maturation and productivity of Japanese quail fed graded concentrations of mercuric chloride Sexual maturation and productivity of Japanese quail fed graded concentrations of mercuric chloride
Japanese quail (Coturnix c. japonica) were fed 0, 2, 4, 8, 16, and 32 p.p.m. Hg as mercuric chloride (HgCl2) from the time of hatching up to the age of 1 year. None of the birds manifested any gross signs of mercury poisoning. Food consumption, growth rate, and weight maintenance were unaffected. Initial oviposition tended to occur at a younger age as dietary mercuric chloride increased...

Mercury in eggs of aquatic birds, Lake St. Clair-1973 Mercury in eggs of aquatic birds, Lake St. Clair-1973
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 levels, less than 0.05-0...

Thermal adaptiveness of plumage color in screech owls Thermal adaptiveness of plumage color in screech owls
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 (MS) have 30 years of data on a northern Ohio Screech Owl population. They...

The effects of orchard pesticide applications on breeding robins The effects of orchard pesticide applications on breeding robins
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 sprayed and unsprayed...

Delta-aminolevulinic acid dehydratase: Inhibition in ducks dosed with lead shot Delta-aminolevulinic acid dehydratase: Inhibition in ducks dosed with lead shot
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. At 3 and 4 weeks, the differences in lead residues were directly

Organochlorine residues in three bat species from four localities in Maryland and West Virginia, 1973 Organochlorine residues in three bat species from four localities in Maryland and West Virginia, 1973
In 1973, 119 bats of three species were collected from four localities in Maryland and West Virginia. The collection included 43 big brown bats (Eptesicus fuscus), 43 little brown brown bats (Myotis lucifugus), and 33 eastern pipistrelles (Pipistrellus subflavus). The bats were collected from Round Top Mountain, Washington Co., Md.; Trout Cave, Pendleton Co., W. Va.; Montpelier Barn...

Organochlorine residues in females and nursing young of the big brown bat (Eptesicus fuscus) Organochlorine residues in females and nursing young of the big brown bat (Eptesicus fuscus)
Carcasses and brains of 18 big brown bats from Gaithersburg, Maryland, were analyzed for residues of organochlorine insecticides and PCB's. Eleven bats were adult females, and six of these had seven nursing young associated with them....Young bats resembled their parents in microgram amounts of PCB and DDE present in carcasses. However, concentrations of chemicals (expressed as ppm) were
