The Ninety-first Stated Meeting of the American Ornithologists' Union was held 8-12 October 1973 at Provincetown, on Cape Cod, Massachusetts, under the sponsorship of the Nuttall Ornithological Club, which was celebrating its centennial year. Business, technical, and social sessions were held in the Provincetown Inn. Field trips were taken...
Retraction of a longevity record for a 36-year-old herring gull
G.M. Jonkel, O.S. Pettingill Jr.
1974, The Auk (91) 432-432
The longevity record for a 36-year-old Herring Gull, Larus argentatus (Pettingill 1967, Auk 84: 123), is erroneous. Herring Gull with band number A-676871, the basis of the record, was found dead on 20 June 1966 on the shore of Little Traverse Bay near Petoskey, Michigan, and reported to the Bird...
Taxonomic status of certain clapper rails of southwestern United States and northwestern Mexico
Richard C. Banks, R. E. Tomlinson
1974, The Wilson Bulletin (86) 325-335
Examination of 58 Clapper Rail specimens taken in the breeding season from the Colorado Valley and the west coast of mainland Mexico verifies the distinctness of the races Rallus longirostris yomanensis, R. 1. rhizophorae, and R. 1. nayaritensis. Rallus 1. yumanensis is a relatively pale brown, pointed-winged, summer resident of...
Record confirmed of Bahama woodstar in Florida
H.P. Langridge, P.W. Sykes Jr.
1974, The Auk (91) 849-849
We reported a Bahama Woodstar (Calliphlox evelynae) at Lantana, Florida, 26 August through 13 October 1971 (1972, Amer. Birds 26: 52). At that time, there was reservation by some about the identification. Colored slides taken of the bird at roost were subsequently examined by James Bond and Frank B. Gill,...

Range expansion and population increase of the gadwall in eastern North America
Charles J. Henny, N.E. Holgersen
1974, Wildfowl (25) 95-101
A disjunct breeding population of Gadwall in eastern North America was first recorded in 1939 This population has extended its range during recent years to the point where it is now found breeding in more than thirty locations (primarily National Wildlife Refuges and Wildlife Management Areas). These are 1,600-2,000 km...
Optimal exploitation strategies for an animal population in a stochastic serially correlated environment
David R. Anderson
1974, Dissertation Abstracts International (35) 3107
Optimal exploitation strategies were studied for an animal population in a stochastic, serially correlated environment. This is a general case and encompasses a number of important cases as simplifications. Data on the mallard (Anas platyrhynchos) were used to explore the exploitation strategies and test several hypotheses because relatively...
Progress report on the North American Breeding Bird Survey
C.S. Robbins, W.T. Van Velzen
1974, Acta Ornithologica (14) 170-191
The Breeding Bird Survey has been monitoring bird population changes in the U.S.A. and Canada since 1966. Each cooperator makes 50 3-minute stops at 0.8-km intervals along randomly selected roadside routes in 4 to 4 1/2 hours on one morning in June of each year. Data from the 1500 to...

The winter bird survey of central Maryland, U.S.A
C.S. Robbins, D. Bystrak
1974, Acta Ornithologica (14) 254-271
A method for monitoring changes in winter bird populations was tested in central Maryland in the winters of 1970, 1971 and 1972. A systematic sample of 41 transects was established to sample an area of 6150 sq. km. Each transect, located at the center of a standard 7 1/2-minute topographic...
The breeding bird atlas of Montgomery County, Maryland, USA
M. K. Klimkiewicz, C.S. Robbins
1974, Acta Ornithologica (14) 446-458
A two-year Breeding Bird Atlas program for Montgomery County was undertaken by the Maryland Ornithological Society in 1971-1972. The county was divided into 65 5 km blocks and each block was assigned to an observer. Preliminary results show 46 to 93 species (mean 66) recorded per 5 km...
Percutaneous absorption of several chemicals, some pesticides included, in the red-winged blackbird
J.G. Rogers Jr., R.H. Cagan, M.R. Kare
1974, Environmental Physiology and Biochemistry (4) 104-111
Percutaneous absorption in vivo through the skin of the feet of the red-winged blackbird (Agelaius phoeniceus) has been investigated. Absorption after 18-24 hours exposure to 0.01 M solutions of salicylic acid, caffeine, urea, 2,4-D, dieldrin, diethylstilbesterol, and DDT was measured. Of these, only DDT and diethylstilbesterol were not...

Relationships between chemical structure and rat repellency: II. compounds screened between 1950 and 1960
Walter A. Bowles, V. A. Adomaitis, J.B. DeWitt, J.J. Pratt Jr.
1974, Technical Report 75-11-FEL.
Over 4,600 compounds, chiefly organic types, were evaluated using both a food acceptance test (Part A) and a barrier penetration bioassay (Part B), to correlate relationships between chemical structure and rodent repellency. These chemicals are indexed and classified according to the functional groups present and to the degree of substitution...
