National Water-Quality Assessment (NAWQA) Program, Long Island-New Jersey (LINJ) Coastal Drainages Study Unit : Scope of the Long Island-New Jersey Coastal Drainages Study-Unit investigation National Water-Quality Assessment (NAWQA) Program, Long Island-New Jersey (LINJ) Coastal Drainages Study Unit : Scope of the Long Island-New Jersey Coastal Drainages Study-Unit investigation
Scope of the Long Island-New Jersey Coastal Drainages Study-Unit Investigation In 1991, the U.S. Geological Survey (USGS) began a National Water-Quality Assessment (NAWQA) Program to document the status of and trends in quality of a large representative part of the Nation's water resources and to provide a sound scientific understanding of the primary natural and human factors that...

Population trends of woodland birds from the North American Breeding Bird Survey Population trends of woodland birds from the North American Breeding Bird Survey
Population trends of woodland birds were summarized from BBS data over 1966-1991, 1966-1979, and 1982-1991. For the entire woodland bird assemblage, increasing species outnumbered decreasing species in all regions except central North America during 1966-1991. However, the proportion of decreasing species increased in most regions during the 19821991 interval. This population trend was...

Falcon versus grouse: flight adaptations of a predator and its prey Falcon versus grouse: flight adaptations of a predator and its prey
Several falcons were trained to fly along a 500 m course to a lure. The air speeds of the more consistent performers averaged about 1.5 times their calculated minimum power speeds, and occasionally reached 2.1 times the minimum power speed. Wing beat frequencies of all the falcons were above those estimated from earlier field observations, and the same was true of wild Sage Grouse...

Prevalence of eustrongylidosis in wading birds from colonies in California, Texas, and Rhode Island, USA Prevalence of eustrongylidosis in wading birds from colonies in California, Texas, and Rhode Island, USA
Snowy Egret (Egretta thula) and Black-crowned Night-Heron (Nycticorax nycticorax) nestlings from colonies in Texas, Rhode Island, and California and Great Egret (Casmerodius albus) nestlings from Texas were examined for eustrongylidosis, or infection by the parasitic nematode Eustrongylides spp. In 31% (24/77) of all broods examined, at least one nestling was infected. Snowy Egret broods...

Use of geoelectrical methods in groundwater pollution surveys in a coastal environment Use of geoelectrical methods in groundwater pollution surveys in a coastal environment
The pollution of coastal aquifers by old landfills can contaminate valuable and scarce water resources in the freshwater lens utilized seasonably by overcrowded communities. The pollutants will ultimately flow into the sea where they may also cause a coastal water pollution problem. We have detected pollution in the freshwater lens from a sanitary landfill near Provincetown, Cape Cod...

Wolf and bear predation on white-tailed deer fawns in northeastern Minnesota Wolf and bear predation on white-tailed deer fawns in northeastern Minnesota
Whitetailed deer (Odocoileus virginianus) fawn mortality was studied during the summers of 1989 and 1990 in northeastern Minnesota. Estimated pooled mortality rates for 21 radio-tagged fawns were 0.44 for the May-June, 0.13 for the July-October, and 0.51 for the May-October intervals. Predation accounted for all mortalities, with wolves (Canis lupus) responsible for 51% of them and black...

Partial migration and wintering localities of American kestrels nesting in the Pacific northwest Partial migration and wintering localities of American kestrels nesting in the Pacific northwest
Based on banding recoveries, an estimated 89.5% of American kestrels (Falco sparverius) nesting in eastern Oregon, eastern Washington, and Idaho (excluding the Snake River Plain) are migratory and primarily migrate to western Mexico for the winter. Band recoveries from Mexico may be biased; however, we do not know whether the bias is toward more or fewer recoveries. The banding data...

Sources of variation in loss rates of color bands applied to adult roseate terns (Sterna dougallii) in the western North Atlantic Sources of variation in loss rates of color bands applied to adult roseate terns (Sterna dougallii) in the western North Atlantic
A model-based analysis was done to test several hypotheses concerning the rates of loss of butt-ended color bands placed on adult Roseate Terns (Sterna dougallii) in the western North Atlantic. These birds were captured and color banded from 1987-1991 at four colony sites, and recaptured from 1989-1992 as part of a study of the population dynamics of this species. Two types of color...
