Responses of Captive Meadow Voles to Flyovers of a Northern Harrier and an American Kestrel
نویسندگان
چکیده
Meadow voles responded to harrier and kestrel flyovers by looking-up and tracking the flight path of the bird, by entering into behavioral freezes, or by running into their nest cans. Voles responded more frequently when they could see, as well as hear, the bird overhead. When they could see the bird overhead, voles responded more frequently to the harrier than to the kestrel. Shifts in the flight pattern of the harrier did not significantly influence vole responses. Responses of voles to aerial predators may be linked to vole selection of areas with heavy protective cover. OHIO J. SCI. 82(5): 238, 1982

Responses of White-Footed Mice and Meadow Voles to Flyovers of an Aerial Predator Silhouette
The response of white-footed mice and meadow voles to a stylized hawk model pulled overhead was studied. Behavior such as looking up and following the path of the model, immobility, and/or entering a nest can was observed and statistically analyzed. Overall responsiveness peaked as the model passed directly overhead. Stationary models elicited fewer instances of immobility than moving models wh...
متن کاملDevelopment of selective partner preferences in captive male and female meadow voles, Microtus pennsylvanicus
Intraspecific social systems vary considerably as a function of environmental parameters (Lott 1984, Behaviour, 88, 266–325). For example, nonmonogamous species may engage in facultative partner preferences and parenting to offset the costs associated with harsher breeding conditions. Because no field or laboratory research has examined nonmonogamous meadow voles under suboptimal conditions (e....
متن کاملFemale meadow voles (Microtus pennsylvanicus) demonstrate same-sex partner preferences.
Female meadow voles (Microtus pennsylvanicus) are territorial during warm months but demonstrate social tolerance under low temperatures. In spring, females nest together and some pairs participate in communal nursing and rearing of young. Because communal nursing involves significant cooperation, selective pair-bonds may develop between 2 nestmates. Using a choice apparatus, the authors determ...
متن کاملAdaptive immune responses are linked to the mating system of arvicoline rodents.
Males generally exhibit reduced immune responses and greater susceptibility to disease than females. The suppressive effect of testosterone on immune function is hypothesized to be one reason why males have lower immune responses than females. Presumably, this effect of testosterone should be more pronounced among polygynous than monogamous species because circulating testosterone is higher amo...
متن کاملEffects of environmental complexity and temporary captivity on foraging behavior of wild-caught meadow voles.
Increased housing of wild nonhuman animals in captivity for conservation, research, and rehabilitation has revealed the importance of systematically analyzing effects of the captive environment on behavior. This study focused on the effects of complexity and time held in captivity on foraging behaviors of wild-caught, adult meadow voles (Microtus pennsylvanicus). Forty-six individuals captured ...
