The influence of capture-recapture methodology on the evolution of the North American Bird Banding Program The influence of capture-recapture methodology on the evolution of the North American Bird Banding Program
Capture-recapture methodology has advanced greatly in the last twenty years and is now a major factor driving the continuing evolution of the North American bird banding program. Bird banding studies are becoming more scientific with improved study designs and analytical procedures. Researchers and managers are gaining more reliable knowledge which in turn betters the conservation of...

North American Breeding Bird Survey annual summary 1990-1991 North American Breeding Bird Survey annual summary 1990-1991
The North American Breeding Bird Survey (BBS) was used to estimate continental and regional changes in bird populations during 1989-1990 and 1990-1991, placing these short-term changes within the context of population trends since 1966. For the entire survey area, 51.7% of the species exhibited increases in population size during 1989-1990, reversing the decreasing tendency exhibited by...

Cryopreservation of American kestrel semen with dimethylsulfoxide Cryopreservation of American kestrel semen with dimethylsulfoxide
Semen samples from 15 male American Kestrels (Falco sparverius) were frozen in dimethyl sulfoxide (DMSO). The semen was thawed 1-14 mo later and used to inseminate six females during three breeding seasons. Kestrels inseminated with thawed semen containing 4% DMSO produced only infertile eggs (N = 14). Kestrels inseminated with thawed semen containing 6%, 8%, or 10% DMSO produced fertile...

Reproduction of mallards following overwinter exposure to selenium Reproduction of mallards following overwinter exposure to selenium
Forty pairs of mallards (Anas platyrhynchos) were fed 15 ppm selenium as selenomethionine for about 21 weeks during winter. Twenty pairs served as controls. At the end of 21 weeks, which coincided with the onset of the reproductive season, selenium treatment was ended. Four birds died while on selenium treatment. Treated females lost weight, and their egg-laying was delayed. Hatching...

Speculations on colonizing success of the African clawed frog, Xenopus laevis (Pipidae), in California Speculations on colonizing success of the African clawed frog, Xenopus laevis (Pipidae), in California
The African clawed frog has been established in California for over twenty years. During that period, populations have spread to most of the drainage systems in southern California. It is suggested that a suite of contributing factors, including morphological, behavioural, and biochemical predator avoidance strategies, and reproductive and feeding (cannibalism) strategies, have aided in...

Nests and eggs of colonial birds nesting in Malheur Lake, Oregon, with notes on DDE Nests and eggs of colonial birds nesting in Malheur Lake, Oregon, with notes on DDE
We describe the nests and eggs of 7 species of colonial birds that nested on Malheur Lake in Malheur National Wildlife Refuge, Oregon, in 1980 and 1981. All nests were constructed over water in stands of hardstem bulrush (Scirpus acutus). We compared nest measurements among species and found significant differences. Nest size was highly correlated with bird body mass. The heavier the...
