Pesticide concentrations in snail kite eggs and nestlings in Florida
From 1970-1977, unhatched snail kite eggs and young that were found dead at nests in Florida were analyzed by gas chromatography for residues of organochlorine pollutants. The 1970 and 1974 material showed measurable amounts of p,p'-DDE, p,p'-DDD, p,p'-DDT, and dieldrin. Dieldrin and polychlorinated biphenyl (PCB) residues were less than 0.1 ppm in the eggs and were detected in only one sample of

Photographic censusing of the 1982-1983 California condor population
An intensive census of the remnant California condor (G. californianus) population based on photographic identification of individuals revealed a minimum of 21 and a probable maximum of .apprx. 24 condors in late summer 1982. Corresponding figures for 1983 were 19 and 22 condors. Two condors are known to have died in the wild since the 1983 census. These data, when compared with earlier population

Evening roosts of the snail kite in Florida
A total of 36 roost sites of the Snail Kite (Rostrhamus sociabilis) were studied in southern Florida, of which four (11%) were used regularly for 6 or more years. Major roosts were also used as nesting sites. All roosts were in flooded marshes and 33 (91.6%) were in stands of coastal-plain willow. Population increase and the number of roosts were strongly correlated. The number of kites arriving a

Environmental contamination in the oil fields of western Pennsylvania
The effects on freshwater wildlife of chronic exposure to oil field discharges are not well known. Collections of wastewater, aquatic invertebrates, fish, salamanders, and small mammals were made in several streams in the oil fields of western Pennsylvania during 1980-81. Estimates of the petroleum content of two wastewater discharges were high (21.9 and 8.4 ppm) and one was low (0.3 ppm). Water c
