Northern bobwhite, gray partridge, and ring-necked pheasant population trends (1966-1988) from the North American Breeding Bird Survey Northern bobwhite, gray partridge, and ring-necked pheasant population trends (1966-1988) from the North American Breeding Bird Survey
We use North American Breeding Bird Survey data to estimate population trends for 1966-1988 for northern bobwhite (Colinus virginianus), ring-necked pheasant (Phasianus colchicus), and gray partridge (Perdix perdix). Bobwhite populations have undergone widespread declines, pheasant have undergone major declines in eastern North America with mixed trends elsewhere, gray partridge have...

Body mass and lipid content of shorebirds overwintering on the south Texas coast Body mass and lipid content of shorebirds overwintering on the south Texas coast
Three species of shorebirds were collected at bimonthly intervals in 1979-1980, from the time of their arrival in early autumn to mid-February, on the south Texas coast. Female Long-billed Dowitchers (Limnodromus scolopaceus) and Western Sandpipers (Calidris mauri) were heavier (P 0.05) than males, but the reverse was true for American Avocets (Recurvirostra americana). Lipid content...

Intersexual and temporal variation in foraging ecology of prothonotary warblers during the breeding season Intersexual and temporal variation in foraging ecology of prothonotary warblers during the breeding season
We studied foraging ecology of Prothonotary Warblers (Protonotaria citrea) over four breeding seasons to determine if this species exhibited sex-specific or temporal variation in foraging behavior. Significant differences between sexes during the prenestling period were found for foraging height and substrate height (foraging method, plant species/substrate, perch diameter, horizontal...

Possible use of wolf, Canis lupus, den over several centuries Possible use of wolf, Canis lupus, den over several centuries
Radiocarbon dating of bones found at a wolf den on Ellesmere Island suggest it probably was used by wolves over 700 years ago.

Comparison of breaking strength and shell thickness as evaluators of white-faced ibis eggshell quality Comparison of breaking strength and shell thickness as evaluators of white-faced ibis eggshell quality
Data from a 1986 field study of white-faced ibis (Plegadis chihi) nesting at Carson Lake, Nevada, were used to compare the utility of eggshell strength measurement and eggshell thickness as indicators of eggshell quality. The ibis population had a history of reproductive failure correlated with elevated egg concentrations of p, p'-DDE, hereafter referred to as DDE. Eggs from 80 nests...

Factors influencing bird foraging preferences among conspecific fruit trees Factors influencing bird foraging preferences among conspecific fruit trees
The rates at which birds visit fruiting individuals of Allophylus edulis (Sapindaceae) differ substantially among trees. Such avian feeding preferences are well-known, but usually involve fruits and trees of different species. Factors controlling avian preferences for particular trees in a population of conspecifics are generally undocumented. To address this issue, I attempted to...
