Effects of environmental pollutants on Connecticut and Maryland ospreys Effects of environmental pollutants on Connecticut and Maryland ospreys

Osprey (Pandion haliaetus) eggs were exchanged between Connecticut and Maryland osprey nests in 1968 and 1969 to test the hypothesis that the decline in reproductive success of Connecticut ospreys was caused by something within the external environment of the eggs. Incubation of 30 Connecticut osprey eggs by Maryland ospreys did not improve the hatching rate. Forty-five Maryland osprey...

The 1973 distribution and abundance of breeding ospreys in the Chesapeake Bay The 1973 distribution and abundance of breeding ospreys in the Chesapeake Bay

An aerial survey in association with several intensive ground surveys yielded the first estimate of the size of the osprey (Pandion haliaetus carolinensis) nesting population in Chesapeake Bay. The 1973 population was estimated at 1,450 ± 30 pairs, of which 713 were on the western shore and 737 on the eastern shore. A small percentage of nonbreeders (possibly 2-5 percent) may be included...

The breeding bird atlas of Montgomery County, Maryland, USA The breeding bird atlas of Montgomery County, Maryland, USA

A two-year Breeding Bird Atlas program for Montgomery County was undertaken by the Maryland Ornithological Society in 1971-1972. The county was divided into 65 5 km blocks and each block was assigned to an observer. Preliminary results show 46 to 93 species (mean 66) recorded per 5 km block and from 10 to 52 species (mean 28) confirmed per block. When the data are combined into 10 km...

The winter bird survey of central Maryland, U.S.A The winter bird survey of central Maryland, U.S.A

A method for monitoring changes in winter bird populations was tested in central Maryland in the winters of 1970, 1971 and 1972. A systematic sample of 41 transects was established to sample an area of 6150 sq. km. Each transect, located at the center of a standard 7 1/2-minute topographic map, was 8 km in length and approximately square in shape. Coverage began at local sunrise on any...
