Dieldrin and DDT: effects on sparrow hawk eggshells and reproduction
Richard D. Porter, Stanley N. Wiemeyer
1969, Science (165) 199-200
Patterns of reproductive failure in declining populations of several European and North American raptorial species were duplicated experimentally with captive American sparrow hawks Falco sparverius that were given a diet containing two commonly used organochlorine insecticides. Major effects on reproduction were increased egg disappearance, increased egg destruction by parent...
Pre-nesting and nesting behavior of the Swainson's warbler
B. Meanley
1969, The Wilson Bulletin (81) 246-257
The Swainson?s Warbler is one of the least known of southern birds. Although fairly common in some parts of its summer range, observations of its breeding biology have been made by very few persons. The present study was conducted mostly at Macon, Georgia; Pendleton Ferry, Arkansas; and Dismal Swamp, Virginia....In...

A cooperative research effort between the ammunition industry and the Bureau of Sport Fisheries and Wildlife is aimed at finding a suitable non-toxic substitute for lead shot. A contract study by an independent research organization evaluated ways of coating or detoxifying lead shot or replacing it with another metal. As...
Nationwide residues of organochlorine pesticides in wings of mallards and black ducks
Robert G. Heath
1969, Pesticides Monitoring Journal (3) 115-123
Nationwide monitoring of organochlorine pesticides in wings of more than 24,000 mallards and black ducks bagged during the1965 and 1966 hunting seasons showed DDE to be the predominant residue, followed in order by DDT, DDD, dieldrin, and heptachlor epoxide. Residues were generally highest in wings from the Atlantic and...
Relationships of the avifauna of San Esteban Island, Sonora

Seven species of geographically variable birds have been reported as part of the resident avifauna of San Esteban Island in the Gulf of California, Sonora. Two of these, the Curvebilled Thrasher and the Blue-gray Gnatcatcher, may not actually have breeding populations there, at least at the present time. Of the...
The Breeding Bird Survey, 1967 and 1968

Archibald McDiarmid, editor(s)
1969, Book chapter, Diseases in free-living wild animals: the proceedings of a symposium held at the Zoological Society of London on 9 and 10 May 1968
Blood protozoa were first reported from wild birds in 1884. Since then numerous surveys throughout the world have demonstrated their presence in a wide variety of hosts and localities with continuing designations of new species. Taxonomic determinations include parasites in the genera Plasmodium, Haemoproteus, Leucocytozoon, Babesia, Lankesterella and Trypanosoma....

Analysis of a 24-Year photographic record of Nisqually glacier, Mount Rainier National Park, Washington
Fred M. Veatch
1969, Professional Paper 631
A systematic coverage of Nisqually Glacier by photographs taken from a network of stations on the ground was begun in 1942 to explore the value and limitations of such photographs as an aid in glacier study. Principles developed may be of value elsewhere, especially for the program 'Measurement of Glacier...
Chemical properties of ground water and their corrosion and encrustation effects on wells
Ivan Barnes, Frank Eldridge Clarke
1969, Professional Paper 498-D
Well waters in Egypt, Nigeria, and West Pakistan were studied for their chemical properties and corrosive or encrusting behavior. From the chemical composition of the waters, reaction states with reference to equilibrium were tested for 29 possible coexisting oxides, carbonates, sulfides, and elements. Of the 29 solids considered, only calcite,...

Analyses by a combination fire- assay-solution-optical-emission spectrographic method of 137 rocks from the Stillwater Complex, Mont., indicate that platinum, palladium, and rhodium are preferentially concentrated in chromitite zones. The A chromitite zone (21 samples) has an average of 988.9 ppb (pans per billion, 10-9) Pt, 2290.2 ppb Pd, and 245.9...
