Feeding habitat use by colonially-breeding herons, egrets, and ibises in North Carolina
Nine species of herons, egrets, and ibises were followed by airplane from a nesting colony near Beaufort, North Carolina to their feeding sites. Except for Cattle Egrets, which flew exclusively to fields and dumps, the birds flew mainly to saltmarsh habitat. The selection of feeding habitats by Great Egrets and Louisiana Herons was directly related to tidal depth. The Great Egret was the only spec

Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)
Back-yard banding above the Patuxent River gorge was limited to early mornings and evenings on 28 days from 20 August through 12 October, and four full days within the same period.Although the number of birds captured per 100 net-hours was well above average in each of the three months, the only species banded in unusually high numbers was the Gray Catbird (68 birds vs. 61, 39, and 32 in 1973, 197

Floods of July 19-20, 1977 in the Johnstown area, western Pennsylvania
Intense rainfall on the evening of July 19 and early morning hours of July 20, 1977, resulted in moderate to record flooding throughout much of an eight-county area of southwest Pennsylvania. In a 400-square-mile area directly north and east of Johnstown, rainfall totals of 6 to 12 inches were measured in a six to eight-hour period. Flood peaks having recurrence intervals greater than 100 years we

A water-quality assessment of the Busseron Creek watershed, Sullivan, Vigo, Greene, and Clay counties, Indiana
Chemical quality of surface water in the 237-square mile Busseron Creek watershed is significantly affected by drainage from coal mines and municipalities. Drainage from coal mines is primarily a problem of higher than normal dissolved-solids concentration, whereas, drainage from municipalities is generally a problem of bacteria and phytoplankton. Generally, the water is calcium bicarbonate type,

Water-quality assessment of the Middle Fork Anderson River watershed, Crawford and Perry counties, Indiana
Surface-water quality in the watershed is generally good except for problem-causing concentrations of bacteria, dissolved oxygen, and phosphorus at some sites along the main stem during low flow and manganese at most sites year-round.Dissolved-solids concentration ranged from 76 to 248 milligrams per liter. Concentrations at sites upstream from reservoirs were greater than those at sites downstrea

Water quality investigation of Francis Slocum Lake, Luzerne County, Pennsylvania
This report summarizes water-quality data collected in the Francis Slocum Lake drainage basin, Pennsylvania, during an assessment from October 1976 to September 1977. Data were collected for nitrogen, phosphorus, carbon, and fecal coliform and fecal streptococcal bacteria.Results of the restricted sampling indicate that nutrient recycling within the lake is sufficient to support the periodic luxur
