A method of approximating range size of small mammals
In summary, trap success trends appear to provide a useful approximation to range size of easily trapped small mammals such as Peromyscus. The scale of measurement can be adjusted as desired. Further explorations of the usefulness of the plan should be made and modifications possibly developed before adoption.

Natal plumage characters in rails
The downy young of the Clapper Rail (Rallus longirostris), King Rail (Rallus elegans), and Virginia Rail (Rallus limicola) are described as totally black in all literature examined by us. Wetherbee (Bird-Banding, 32: 141-159, 1961) noted that some neonates of Virginia Rail from Storrs, Connecticut, had patches of white down below the wings. "Neonatal" pertains to the developmental condition or c

A method for estimating fall adult sex ratios from production and survival data
This paper presents a method of utilizing data relating to the production and survival of a bird population to estimate a basic fall adult sex ratio. This basic adult sex ratio is an average value derived from average production and survival rates. It is an estimate of the average sex ratio about which the fall adult ratios will fluctuate according to annual variations in production and survival.

Epizootiologic studies on filarioids of the raccoon
Filarioid worms (Dirofilaria immitis, D. tenuis, Dipetalonema procyonis, and D. llewellyni) were discovered in raccoons (Procyon lotar) in Maryland. Raccoons were trapped in lowland, upland, and agricultural-residential areas, which were further classified as stream borders, poorly drained, and well drained. Data on incidence of D. llewellyni were analyzed on basis of host distribution within th
