Energy Utilization of Natural Prey Items by Southeastern Bobcats

Energy utilization of natural prey items by Mississippi bobcats (Felis rufus) was measured and annual prey requirements were estimated. Male and female bobcats were fed 5 diets of natural prey items, December 1990-February 1991. There were significant differences in amount of energy (kcal) in prey items, with white-tailed deer (Odocoileus virginianus) meat (5.7295) greater (P < 0.05) than fox squirrel (Sciurus niger) (5.0304). The deer diet also was significantly greater (P < 0.05) than the rodent diet and the rabbit and rodent diets in metabolizable energy (ME) and metabolizable...

Bobcat Home Range, Density, and Habitat Use in East-central Mississippi

Fifteen bobcats (10 females, 5 males) were monitored using radio telemetry from 1 January 1989-31 December 1991 in east-central Mississippi. Male composite home ranges (HR) averaged 36.5 km2 (S.E. = 12.7) while female HR's averaged 20.6 km2 (S.C. = 7.7). Composite and seasonal HR sizes differed between sexes (P = 0.03 and P < 0.001, respectively). HR's were larger during the 1989 post-parturition (1 May-31 Aug) and fall (1 Sept-31 Dec) seasons than during most other seasons (P < 0.05). Intersexual HR overlap occurred during 5 of 9 seasons. Female-female HR overlap occurred during 3...

Wild Turkey Use of Loblolly Pine Plantations for Nesting and Brood Rearing

Wild turkey (Meleagris gallopavo) hens were monitored by telemetry from January 1987 through August 1988 in Kemper County, Mississippi. Thirty-nine of 52 hens reached incubation. Nesting success was 46% in 1987 and 36% in 1988. In 1987, all 12 located nests were in loblolly pine (Pinus taeda) plantations. Eleven hens nested in 17- to 19-year-old plantations; I hen nested in a 9-year-old plantation. In 1988,21 located nests were in plantations and I hen was in a mature pine-hardwood forest. Most hens (81 %) nested in plantations age 13-20 years old. Plantations used for nesting had been...

Anatomical Development of Captive Bobcats in Mississippi

The eyes of bobcat (Felis rufus) kittens opened between 9 and 16 days of age in 3 stages (watering, beginning to open, and complete opening) lasting 1-2 days each. Birth weights averaged 125 g. Growth curves peaked at 60 weeks (x¯ = 10 kg) for males and at 55 weeks (x¯ = 8 kg) for females. Log transformations of nose to rump length, and front leg length were highly correlated with age (r ≥ 0.94).
