The Animal Welfare Act and the zoo: A positive approach The Animal Welfare Act and the zoo: A positive approach
Interpretations of the Animal Welfare Act and other regulations governing use of research animals in the United States are changing. Recent amendments to the Act have resulted in the inclusion of more species under the umbrella of regulation. The role of the zoo and wildlife veterinarian should be that of leading his or her institution into a positive endorsement of these regulations and...

Statistical considerations in designing raptor surveys Statistical considerations in designing raptor surveys
Careful sampling design is required to obtain useful estimates of raptor abundance. Well-defined objectives, selection of appropriate sample units and sampling scheme, and attention to detail to reduce extraneous sources of variability and error are all important considerations in designing a raptor survey.

Generalized procedures for testing hypotheses about survival or recovery rates Generalized procedures for testing hypotheses about survival or recovery rates
Comparisons of survival or recovery rates from different time periods or geographic regions may be difficult to accomplish using the Z-tests suggested by Brownie et al. (1985). We propose a general Chi-square statistic that addresses an unambiguous null hypothesis of homogeneity among several survival or recovery rates. With this statistic, specific hypotheses of differences in rates can...

Longevity records of North American birds. Supplement 1 Longevity records of North American birds. Supplement 1
This is the first supplement to the previous published four-part series on avian longevities (Clapp et al. 1982, 1983; Klimkiewicz et al. 1983; Klimkiewicz and Futcher 1987). R ecords processed in the Bird Banding Laboratory through August 1988 are included, as well as several corrections to the original series. One hundred-seven of the 147 entries in this supplement are new longevity...

Organochlorine contaminants in white-faced ibis eggs in southern Texas Organochlorine contaminants in white-faced ibis eggs in southern Texas
White-faced ibis eggs collected from 2 colonies in southern Texas in 1985 had low mean concentrations of DDE. DDD, the only other organochlorine contaminant detected, was found in only 1 of 20 eggs. DDE concentrations in eggs were not significantly correlated with eggshell thickness. Mean DDE concentrations were significantly higher in eggs collected from nests where not all of the...

Avian community response to small-scale habitat disturbance in Maine Avian community response to small-scale habitat disturbance in Maine
The effects of small clearcuts (1 - 8 ha) on avian communities in the forest of eastern Maine were studied using point counts during spring 1978 - 1981. Surveys were conducted in uncut (control) and clear-cut (treatment) plots in three stand types: conifer, hardwood, and mixed growth. We used a mark-recapture model and its associated jackknife species richness estimator (N), as an...
