Techniques and results of nongame bird monitoring in North America Techniques and results of nongame bird monitoring in North America
Long-term bird population trends based on accumulated ratios (proportional change) sometimes give a very misleading view of population change. Alternate methods of representing population change, based on the weighted means for the individual years, avoid the dangers of using ratios. Some advantages and disadvantages of various weighting techniques are discussed.

The American Ornithologists' Union and its members had an early history of involvement in public affairs and conservation activities. A very active Committee on Bird Protection was among the first of the service committees to be established. In the 1880s it gathered data on the plumage trade and worked for legislation to protect birds, preparing a model law for the protection of nongame...

Effects of toxaphene and endrin at very low dietary concentrations on discrimination acquisition and reversal in bobwhite quail, Colinus virginianus Effects of toxaphene and endrin at very low dietary concentrations on discrimination acquisition and reversal in bobwhite quail, Colinus virginianus
Adult male bobwhite quail Colinus virginianus were fed toxaphene (chlorinated camphene, 67–69% chlorine) at 10 and 50 ppm or endrin (1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-1,4-endo-endo,5,8-dimethanonaphalene) at 0·1 and 1·0 ppm and their performance on non-spatial discrimination reversal tasks was measured. The birds were on dosage for 138 days (beginning at the...

Estimating the size and trend of the California condor population, 1965-1978 Estimating the size and trend of the California condor population, 1965-1978
During 1965-1978, three principal methods were used to measure the size and trend of the California Condor (Gymnogyps californianus) population. An October survey conducted by as many as 136 observers had limited value because daily activity patterns of condors were unpredictable and because analysis of results could not be standardized. Evaluation of 4,381 condor observations by...
