Reproductive success of Potomac River ospreys--1970
Stanley N. Wiemeyer
1971, Chesapeake Science (12) 278-280
Osprey reproductive success on the Potomac River during 1970 is described. Thirty-five percent of the accessible active nests fledged young and only 0.70 young were fledged per active nest. Egg failure was the major cause of poor success. Reproduction was below that considered normal for a stable population....

Transcontinental mourning dove recovery

A Mourning Dove (Zenaida macroura) banded in New York has been reported shot in California. On 25 August 1969, near Palmyra (43°00' N, 77°10' W), New York Department of Environmental Conservation personnel placed U. S. Fish & Wildlife Service band 883-97279 on the leg of a hatching-year Mourning Dove of...

If you have a recovery which is worthy of a note, it should be verified first with either the Banding Laboratory, where all the recovery letters are kept on file, or with the person who found the band....
Organochlorine pesticide residues in woodcock, soils and earthworms in Louisiana, 1965
M. Anne Ross McLane, L.F. Stickel, J.D. Newsom
1971, Pesticides Monitoring Journal (5) 248-250
Woodcock (Philohela minor), earthworms, and soil samples were collected from January-March 1965, from fields in southeastern Louisiana approximately 3 years after discontinuance of areal treatments with heptachlor in this region. Heptachlor epoxide residues in woodcock averaged 0.42 ppm (dry weight), conspicuously lower than in 1961 and 1962. Residues...

Semiquantitative determination of polychlorinated biphenyls in tissue samples by thin layer chromatography
B.M. Mulhern, E. Cromartie, W. L. Reichel, A. A. Belisle
1971, Journal of the Association of Official Analytical Chemists (54) 548-550
A method is described for the analysis of polychlorinated biphenyl (PCB) compounds in tissue samples. Cleanup by hexane-acetonitrile partitioning and Florisil column chromatography are performed on samples before oxidative treatment to convert DDE to DCBP. PCB components are then determined semi-quantitatively by TLC. No prior separation of PCB from chlorinated...
DDE thins eggshells and lowers reproductive success of captive black ducks
J. R. Longcore, F. B. Samson, T.W. Whittendale Jr.
1971, Bulletin of Environmental Contamination and Toxicology (6) 485-490
Eggs of captive black ducks fed diets containing DDE at 10 and 30 ppm (dry weight) experienced significant shell thinning and an increase in shell cracking when compared to eggs of untreated black ducks. Eggshells from dosed ducks were: 18-24 percent thinner at the equator than shells from undosed...
