Odocoileus Hemionus Columbianus

The feed intake, resting heat production, and growth rate of prepubertal black-tailed deer fawns of both sexes have been studied under captive conditions. Comparisons of these findings with those of other workers on domestic and other wild species are presented. The present results provide some explanation for the unusual growth behavior of this species when reared on a high plane of nutrition.

Growth rate and potential, 25 hand-reared mule deer (Odocoileus hemionus hemionus) were examined. When possible, body weights of all animals were recorded weekly. Female deer matured faster than males, but males attained a larger body size. Regressions of winter weight loss of both sexes on peak autumn weight were highly correlated. Similarly, spring and summer compensatory gain in females could be predicted from the minimum spring weight. Annual cycles of intake and weight gain may have adaptations that improve reproductive success and winter survival.

First Time

Foraging bouts of captive black-tailed deer (Odocoileus hemionus columbianus Richardson) were investigated to examine how searching for food affects diet selection. We determined food preference for three types of food under ad libitum conditions and then studied the foraging of two deer in a 0.5-ha, vegetation-free pen in which we controlled food availability and distribution of the same three types of food. Our hypotheses included the following: (i) clumping of preferred food into patches would enable animals to better exploit food distributions; (ii) the switch from preferred to lower-ranked food would be gradual as preferred food was less frequently encountered; and (iii) deer would respond to a lower abundance of preferred foods by eating more of lower-ranked food items at each feeding location. Searching for food alone did not alter diet selection from ad libitum conditions. Deer nearly exhausted their highly preferred food item before switching to lower-ranked ones. Amount of preferred food already eaten during a trial was positively correlated with the time that animals continued searching before switching to lower-ranked food items. Switching was related to amount and type of food encountered and not to amount of food in the pen. Clumping of the preferred food had no significant effect on the amount of food eaten, but did significantly influence types of food encountered by one deer. When preferred food was abundant, it was not always completely eaten the first time a feeding platform was visited. Increases in the intake rates of nonpreferred food items resulted from deer visiting more feeding stations containing nonpreferred food items and not from deer eating more food at each feeding station.

Abstract Edible biomass estimating regression equations were developed for red huckleberry (Vaccinium parvifolium), understory western red-cedar (Thuja plicata) and deer fern (Blechnum spicant) growing in potential second-growth Columbian black-tailed deer (Odocoileus hemionus columbianus) winter range on Vancouver Island, B.C. Vertical edible biomass height profile equations were also developed for red huckleberry and western red-cedar. These models may be used to objectively and conveniently help assess the amount of forage available to deer during severe winters. West. J. Appl. For. 7(2):48-50.

Prey System

Direct effects of predators depend upon factors that can vary across seasons, including variations in the abundance and vulnerability of migrating prey. Past studies show conflicting results of whether puma (Puma concolor (L., 1771)) feeding ecology varies among seasons. We employed GPS collars to study puma feeding ecology in a single-prey system with migratory black-tailed deer (Odocoileus hemionus columbianus (Richardson, 1829)). We hypothesized that puma feeding ecology would vary based on changes in prey abundance and spatial distribution, as well as competition with scavengers and decomposers. Our results supported these hypotheses. Kill rates in number of ungulates/week were significantly higher in summer and autumn than in winter, likely owing to the increased availability and density of black-tailed deer fawns. The handling times of black-tailed deer ≥1 year old were significantly higher in winter than in spring, summer, or autumn. We speculated that reduced handling time in summer may have been influenced by black bear (Ursus americanus Pallas, 1780) kleptoparasitism and the decomposition of kills. Pumas killed black-tailed deer at higher elevations in summer than in winter, spring, or autumn, and the elevations correlated significantly with seasonal elevations used by black-tailed deer, suggesting that pumas exhibited seasonal foraging behaviours and tracked prey availability in a system with migrating prey.

Effect Of Age

A study has been made of the normal chemistry of the blood constituents of the Columbian black-tailed deer (Odocoileus hemionus columbianus) in relation to growth and the caloric plane of nutrition. The results showed a significant difference of packed-cell volume and hemoglobin level between the two age groups of experimental animals, while no significant differences were found in the sedimentation rates. The high and low imposed planes of nutrition did not bring about a significant difference in packed-cell volume, sedimentation rate, or hemoglobin value.
