Canada Lynx in the Great Lakes Region 2005 Annual ReportMale and Female Home Range SizesMale lynx range more widely than female lynx (Fig. 4b). Females with kittens tended to havean even smaller area of use than females without kittens (Fig. 4a). The home ranges of adult femaleswith kittens tended to be smallest, while males had the largest home ranges (Table 4). Females withkittens did not move far in any season, maintaining site fidelity in relatively small areas (Fig. 5).Figure 4. Examples of 50% and 95% kernel home ranges for radiocollared Canada lynx. Kernel home rangesare essentially contour maps showing areas representing a percentage of an animal’s home range. The smallesthome ranges (a) are used by females with kittens. Intermediate size home ranges are usually from smallerfemales and males, while larger home ranges such as those in (b) are from adult males.(a)(b)Figure 5.
