During spring 1981, 112 radio-equipped female pheasants (Phasianus
colchicus), were released in the Willamette Valley, Oregon. Hens were
monitored to determine location of nest and brood-rearing sites.
Vegetation around each nest and brood-rearing site was classified as
one of 5 cover types available on the study areas. Further

An investigation of the correlation between a number of behavioral,
morphological and physiological parameters and dominance status of male
Ring-necked Pheasants (Phasianus colchicus) was undertaken. Dominant
males performed significantly more aggressive behaviors than
subordinates and a higher proportion of these behaviors was directed
toward distantly ranked subordinates. Animals could also...
Prior to onset of the breeding season, a ration containing 18.4 mg/kg N-(Ethylmercuri)-p-toluene sulphonanilide was fed to 6 male and 16 female ring-necked pheasants (Phasianus colchicus). Birds
receiving the mercury-treated ration were separated from the opposite sex. After receiving the mercury-treated ration for 0, 2, 4, 8, or 16 days,...

A declining population of ring-necked pheasants (Phasianus colchicus) was
studied at Tule Lake National Wildlife Refuge (TLNWR) from the summer of 1990
through the spring of 1993. Pheasant densities/50 ha at TLNWR in 1989, 1991, and
1992 were considerably lower (16.86, 8.49, and 6.81) than the >62 density seen in...
