Status of the everglade kite in Florida--1968-1978
P.W. Sykes Jr.
1979, The Wilson Bulletin (91) 495-511
The population status of the Everglade Kite (Rostrhamus sociabils plumbeus) was studied in Florida from 1968 through 1978. Sixty-four nestlings (40% of known fledged young) were leg-banded with unique color combinations, and of these, 17.2% were seen 1 or more years after they were banded. Kites were capable of breeding...
Nationwide residues of organochlorine compounds in starlings (Sturnus vulgaris), 1976
Donald H. White
1979, Pesticides Monitoring Journal (12) 193-197
Organochlorine pesticide and PCB residues in starlings from 126 sites within the contiguous 48 states were monitored during fall 1976. The average nationwide level of DDE and PCBs has increased significantly since 1974, but the number of sites reporting PCB residues has decreased fivefold. Dieldrin residues have remained unchanged since...
Effects of No. 2 fuel oil on hatchability of marine and estuarine bird eggs
Donald H. White, Kirke A. King, Nancy C. Coon
1979, Bulletin of Environmental Contamination and Toxicology (21) 7-10
Eggs of Louisiana herons, sandwich terns, and laughing gulls were oiled with either 0, 5, or 20 μl of No. 2 fuel oil in the field and in the laboratory. After 5 days of natural incubation, field-oiled and control eggs were opened and embryonic mortality was determined. No. 2 fuel...
The light-footed clapper rail: An update
Cynthia A. Wilburn, Paul D. Jorgensen, Barbara W. Massey, Venita A. Basham
1979, American Birds (33) 251-215
A preliminary report on the Light-footed Clapper Rail, Rallus longirostris levipes, estimated a population of 500-750 birds in California (Wilbur, Am. Birds 28:868-870, 1974). Since then, additional work has been accomplished, most notably: (1) an intensive study of Carpinteria Marsh, Santa Barbara County, 1976-1977 (Basham); (2) a series of winter...
Feeding ecology and development of juvenile black ducks in Maine
Kenneth J. Reinecke
1979, The Auk (96) 737-745
Data from 41 juvenile Black Ducks (Anas rubripes) collected in the Penobscot River valley of Maine from June through August 1974-76 were used to estimate the proportion of aquatic invertebrates in the prefledging diet and the allometric growth rates of the tarsi, flight muscles, and alimentary system. The proportion of...
Scent-marking in lone wolves and newly formed pairs
R.J. Rothman, L.D. Mech
1979, Animal Behaviour (27) 750-760
Scent-marking was studied in wolves (Canis lupus) along 133 km of tracks in northern Minnesota during winters of 1975 to 1976 and 1976 to 1977 and in two captive packs and four captive pairs for various periods. Lone wolves, which possess neither mates nor territories, rarely marked by raised-leg...

H. M. Ohlendorf, J. B. Elder, Rey C. Stendell, Gary L. Hensler, R.W. Johnson
1979, Pesticides Monitoring Journal (13) 115-119
Chicks of great blue herons (Ardea herodias) from four heronaries located near South St. Paul, Royalton, and Wabasha, Minnesota, and La Crosse, Wisconsin, were analyzed for organochlorines, Highest mean wet-weight concentrations, 6.43 ppm PCBs. 1.31 ppm DDE, and 1.90 ppm sigma DDT, were found in the South St. Paul chicks....
