Symptoms and circumstances associated with bites by the brown tree snake (Colubridae: Boiga irregularis) on Guam Symptoms and circumstances associated with bites by the brown tree snake (Colubridae: Boiga irregularis) on Guam
A review of 94 cases of snakebite by the brown tree snake, Boiga irregularis, in Guam spanning a two year period shows a high proportion (80%) involve victims bitten while sleeping in their homes at night. Some bites apparently involve attempts to feed on small children. Of all children less than 1 yr old that were bitten in a two year period, infants 1-3 mo old comprised 82%. The...

Diurnal habitat use of American woodcock wintering along the Atlantic coast Diurnal habitat use of American woodcock wintering along the Atlantic coast
The long-term decline of the American woodcock (Scolopax minor) population led us to investigate diurnal habitat use with radiotelemetry on the wintering grounds. Sites included the coastal plain of Georgia (1989-1991), South Carolina (1988-1989), and Virginia (1991-1992). Habitat use was not explained by age, sex, or date during the winter, but individuals used habitat differently (P 0...

Distribution and abundance of birds wintering in Maryland, 1988-1993 Distribution and abundance of birds wintering in Maryland, 1988-1993
A winter bird survey was conducted throughout Maryland, primarily by volunteers, during the 6 winters of 1988 to 1993 between the dates of 10 Jan and 10 Feb. The state of Maryland is covered by 1231 blocks (9.5 sq. miles each), each comprising one-sixth of the standard U.S.G.S. 7.5 minute topographic quadrangle, and 548 of these blocks (44.5%) were surveyed for winter birds. Blocks were...

Survival and causes of mortality in juvenile Puerto Rican parrots Survival and causes of mortality in juvenile Puerto Rican parrots
Fifteen juvenile Puerto Rican Parrots (Amazona vittata) from wild nests in 1985, 1986 and 1987 were radio monitored an average of 110 +- 15.9 (SE) d (range 4-209 d) post-fledgling. Minimum survival was 67% (n = 3) in 1985, 100% (n = 4) in 1986 and 43% (n = 7) in 1987. Most mortality (three of five deaths) occurred during the first 35 d following fledgling. A major cause of mortality was...

On the importance of sampling variance to investigations of temporal variation in animal population size On the importance of sampling variance to investigations of temporal variation in animal population size
Our purpose here is to emphasize the need to properly deal with sampling variance when studying population variability and to present a means of doing so. We present an estimator for temporal variance of population size for the general case in which there are both sampling variances and covariances associated with estimates of population size. We illustrate the estimation approach with a...

Carbofuran affects wildlife on Virginia corn fields Carbofuran affects wildlife on Virginia corn fields
Forty-four Virginia corn fields on 11 farms were searched for evidence of dead or debilitated wildlife following in-furrow application of granular carbofuran (Furadan 15G) during April and May 1991. Evidence of pesticide poisoned wildlife, including dead animals, debilitated animals, feather spots, and fur spots was found on 33 fields on 10 farms. Carcasses of 61 birds, 4 mammals, and 1...
