Foraging Behavior of the Pika (Ochotona princeps), With Comparisons of Grazing Versus Haying
Huntly NJ, Smith AT, Ivins BL. 1986. Foraging Behavior of the Pika (Ochotona princeps), With Comparisons of Grazing Versus Haying. Journal of Mammalogy. 67(1):139-148
Pikas inhabit areas with talus and forage on surrounding vegetation. Their foraging behavior was consistent with several predictions of central place foraging theory. Intensity of foraging decreased with distance from talus, whereas selectivity increased. Plant abundance and species richness increased with distance from talus. Differences between grazing and haying behaviors appear to reflect differences in costs and benefits between these activities.
