Food Habits of Hunter Collected Northern Bobwhite Quail in South Texas

We investigated the feeding habits of wild northern bobwhites (Colinus virginianus) harvested from the Chaparral Wildlife Management Area in south Texas in October 2004 and January 2005. The contents of 200 crops were dried, sorted, and weighed to the nearest 0.0001 g. Percent dry weight was used to assess differences among season harvested, sex, and age. About 76% of the fall diet consisted of seeds, with 64 plant species represented. Croton (Croton spp.), woolly croton (Croton capitatus), and bristlegrass (Setaria sp.) composed greater than 50% by weight of seeds found in the fall diet....


Antler Characteristics and Body Mass of Spike- and Fork-antlered Yearling White-tailed Deer at Maturity

We compared antler characteristics and body mass at 4.5 years of age (adult) of 140 white-tailed deer (Odocoileus virginianus) reared in a captive herd at the Kerr Wildlife Management Area (Hunt, Texas) from 1973 to 1990. Each yearling (1.5 years old) was classified as spike- (N = 43) or fork-antlered (N = 97), and its live body mass recorded. Fork-antlered yearlings were further partitioned into 3-5 points (N = 33) and ≥6 points (N = 64) subclasses based on the number of antler points ≥2.54 cm in length. All deer were reared in 1.62-ha enclosures and maintained on a 16% crude protein diet...
