A summary of alcid records from Hawaii
R. B. Clapp
1986, Colonial Waterbirds (9) 104-107
Abstract.-Four species of alcids have now been recorded frorn Hawaii. Two of them, the Tufted Puffin (Fratercula cirrhata and the Cassin's Auklet (Ptychoramchus aleuticus) have been found only once; the occurrence of the latter is reported here for the first time. two other alcids, the Horned Puffin (Fratercula arctica) and...
A taxonomic reevaluation of the plain pigeon (Columba inornata)
R.C. Banks
1986, The Auk (103) 629-631
Three subspecies of the Plain Pigeon (Columba inornata) were described in 1915 from very small samples, and the diagnostic color differences among them were rather minor. Examination of the small series (including two types) of the subspecies in the National Museum of Natural History (USNM) revealed that the quality of...
Toxicity of methyl parathion to bats: Mortality and coordination loss
D. R. Clark Jr.
1986, Environmental Toxicology and Chemistry (5) 191-195
The 24-h oral LD50 of methyl parathion (phosphorothioic acid O, O-dimethyl O-(4-nitrophenyl) ester) to little brown bats (Myotis lucifugus) (372 mg/kg) was 8.5 times the LD50 for mice (Mus musculus) (44 mg/kg). However, orally dosed mice either died or appeared behaviorally normal after 2 to 3 h, whereas many dosed bats,...
Mid-winter food use and body weights of mallards and wood ducks in Mississippi
Don Delnicki, K. J. Reinecke
1986, Journal of Wildlife Management (50) 43-51
We obtained esophageal food samples from 311 mallards (Anas platyrhynchos) and 94 wood ducks (Aix sponsa) and body weights from 2,118 mallards and 315 wood ducks in western Mississippi during December and January 1979-83. On average, mallards ingested 3.0% animal food, principally aquatic invertebrates, and 97.0% plant food. Rice, soybeans,...
Subspecies of the greater scaup and their names
R.C. Banks
1986, The Wilson Bulletin (98) 433-444
The name Fuligula mariloides Vigors, presently used by many authors for a subspecies of the Greater Scaup, Aythya marila, was originally proposed for the Lesser Scaup, A. afinis, and may not be used in combination with the name marila. The name mariloides has been applied to a population of Greater...
Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria)
Matthew C. Perry
1986, Dissertation Abstracts International (46B) 3291 (abs)
Captive canvasbacks (Aythya valisineria) were maintained ad libitum on five diets during the winters of 1978-79 and 1979-80 to evaluate the effects of varying protein and energy levels on feed intake and condition. Diets were formulated to simulate either a natural diet high in invertebrates or one high in vegetation....
Use of an inactivated eastern equine encephalitis virus vaccine in cranes
J. W. Carpenter, F. J. Dein, G.G. Clark, D.M. Watts, C.L. Crabbs
1986, American Association of Zoo Veterinarians, Annual Proceedings (1986) 88 (abs)
An unprecedented outbreak of fatal eastern equine encephalitis (EEE) virus occurred during the late summer and fall of 1984 in endangered whooping cranes (Grus americana) at the Patuxent Wildlife Research Center, Laurel, Maryland. As part of efforts to prevent future epizootics of EEE. studies were conducted to evaluate the...
Range extension for the gray-backed tern in the western Pacific
R. B. Clapp, J.J. Hatch
1986, Colonial Waterbirds (9) 110-112
About 75 pairs of Gray-backed Terns (Sterna lunata) nested on Guguan in the Northern Mariana Islands in 1979. This locality represents a breeding range extension of about 2000 km to the west of the westernmost previously known colony. The species is also reported for the first time from Uracas, northernmost...
Constant-parameter capture-recapture models
C. Brownie, J.E. Hines, J.D. Nichols
1986, Biometrics (42) 561-574
Jolly (1982, Biometrics 38, 301-321) presented modifications of the Jolly-Seber model for capture-recapture data, which assume constant survival and/or capture rates. Where appropriate, because of the reduced number of parameters, these models lead to more efficient estimators than the Jolly-Seber model. The tests to compare models given by Jolly do...
Embryonic mortality and abnormalities of aquatic birds: Apparent impacts of selenium from irrigation drainwater
H. M. Ohlendorf, D. J. Hoffman, M. K. Saiki, Thomas W. Aldrich
1986, Science of the Total Environment (52) 49-63
Severe reproductive impacts were found in aquatic birds nesting on irrigation drainwater ponds in the San Joaquin Valley of California. Of 347 nests studied to late incubation or to hatching, 40.6% had at least one dead embryo and 19.6% had at least one embryo or chick with an obvious external...
Association between PCBs and lower embryonic weight in black-crowned night herons in San Francisco Bay
D. J. Hoffman, Barnett A. Rattner, C.M. Bunck, A. J. Krynitsky, H. M. Ohlendorf, Roy W. Lowe
1986, Journal of Toxicology and Environmental Health (19) 383-391
Reproductive problems, including congenital malformations, reduced hatching success, and decreased survival of hatchlings, have been observed in colonial-nesting water birds at the San Francisco Bay National Wildlife Refuge (SFBNWR). Twenty-four black-crowned night heron (Nycticorax nycticorax) eggs were collected from SFBNWR in 1983. Twelve of these were collected...
Reproductive toxicity of monocrotophos to bobwhite quail
K. L. Stromborg
1986, Poultry Science (65) 51-57
Pairs of 1st-year breeding bobwhites were fed constant or decreasing concentrations of monocrotophos for 15 days. In addition, a control diet was used in a pair-fed group matched with the pairs in the constant group. Dietary concentrations for the constant group were logarithmically spaced at .100, .178, .316, .562, 1.000...
DDE, DDT + dieldrin: Residues in American kestrels and relations to reproduction
Stanley N. Wiemeyer, Richard D. Porter, Gary L. Hensler, J.R. Maestrelli
1986, Fish and Wildlife Technical Report 6
Captive American kestrels (Falco sparverius) given long-term dietary dosages of DDT and dieldrin in combination, at low and high rates, were compared with controls to determine the effects of the toxicants on reproductive success and eggshell thickness. Additional kestrels were dosed with DDE to determine its effect on shell...
Forested wetlands of the Southeast: Review of major characteristics and role in maintaining water quality
Parley V. Winger
1986, Resource Publication 163
Forested wetlands occupying floodplains of major rivers in the Southeast are highly productive and diverse ecological systems. The wetlands are produced and maintained by fluvial processes and unique hydrologic regimes consisting of periodic flooding and subsequent drydown. Fluctuations in soil chemistry and biology resulting from this flooding and...
Wolf population in the Central Superior National Forest, 1967-1985
L.D. Mech
1986, Research Paper NC-270
Aerial radio-tracking and observation showed total number of wolves per year in 2,060-km2 area varied from 35 to 87 in winter and from 30 to 78 in spring and generally declined because of a decreasing deer herd. Since winter 1977-1978, the population has remained relatively stable because an increasing proportion...
Deer population in the Central Superior National Forest, 1967-1985
M.E. Nelson, L.D. Mech
1986, Research Paper NC-271
Deer were aerially censused each winter from 1976 through 1985 in a 400-sq km2 area near Isabella, Minnesota, in the Central Superior National Forest; a correction factor based on aerial observability of radio-tagged deer in the same region was then applied to the census figures. Deer numbers, which had reached...

C.S. Robbins, D. Bystrak, P.H. Geissler
1986, Resource Publication 157
The Breeding Bird Survey (BBS) is an ongoing cooperative program sponsored jointly by the U.S. Fish and Wildife Service and the Canadian Wildlife Service.
