“…In raccoon dogs there is a weak, intra-specific population pressure due to low-developed territoriality and probable lifelong pair bonds (Kauhala et al, 1998;Drygala et al, 2000;Kauhala and Saeki, 2004;Kauhala et al, 2006). Thus, in contrast to pack living canids each animal provides an independent measure of habitat use within the population.…”

This study investigated habitat availability and its selection and preference by adult, resident raccoon dogs inhabiting the countryside in north-eastern Germany. Habitat composition within home ranges and within the whole study area was almost equal. Although percentage share of farmland and meadow was 16.35% smaller and 12.06% higher within the home ranges, respectively. All nine habitat types (farmland, forest, settlement, water, meadows, maize fields, small woods, reeds and hedges) were used opportunistically by raccoon dogs. No significant, recognisable difference for habitat preferences between seasons was detected. Male and female raccoon dog showed equal habitat preference pattern. A comparison of active and inactive locations in different habitats found no remarkable differences.Habitat composition of individual home ranges was used to classify animals. If the percentage of forest within a home range exceeded 50% the individual was classified as a 'forest type' raccoon dog. If the percentage of forest habitats within a home range was less than 5%, the share of pastureland was mean 81.82%716.92 SD. Consequently the individual was classified as a 'agrarian type' raccoon dog. Neither habitat preference nor habitat selection process differed between the two 'types'. Habitat use and preference is discussed with relation to the ability of the raccoon dog to expand its range towards Western Europe.

“…This probably reflects the fact that the male could bring prey items or supplemental food to the nest [see Kauhala et al, 1998]. It may of course be that the male was performing other important roles necessary for the survival of offspring such as territorial marking.…”

“…In small insectivorous canids such as the hoary fox (Pseudalopex vetulus) or the raccoon dog (Nyctereutes procyonoides), males often spend a considerable amount of their time budget caring for their offspring [Courtenay et al, 2006;Kauhala et al, 1998]. This is thought to be owing to the difficulty males have in bringing insect prey items back to their females or offspring.…”

In many species of canids the male's role in reproduction extends to providing extensive or some parental care to his offspring. Maned wolves are a monogamous canid species whose males have been observed providing parental care to their offspring in captivity, but no field observations exist. We observed a wild pair of maned wolves at their nest site in a period soon after the female had given birth for a total period of 65 days. We made five observation sessions with an average of 3-4 days each separated by approximately 2 weeks. Direct visual observations of maned wolves were made each 30 min during the hours of darkness (17:00-07:00) using night-vision binoculars and confirmed by VHF radiotelemetry. During observations we recorded the location of the male and the female in relation to the nest (i.e., in the nest, nearby or long way from the nest). The results showed that the female spent more than 60.44% of her time in or near the nest. The male spent 28.90% of his time in or near the nest. There was a positive significant correlation between the female and the male in terms of the amount of time spent in or near the nest (P<0.01). The maned wolves showed a strong temporal variation in time spent in or near the nest. In conclusion, our data show that wild male maned wolves--probably--provide parental care through provision of food to their female and presumed offspring rather than "babysitting."

“…As reported by , members of the pair spent 84% of time together in winter and 67% in summer. Decrease of joint resting during the breeding period results from time allocation of male and female to pup rearing and food collection (Kauhala et al 1998, Drygala et al 2008b). Both parents participate in care for pups, and both parents, or one of the individuals, always guard pups during first 6 weeks after parturition while the other forages (Drygala et al 2008b).…”

Based on radio-tracking of raccoon dogs Nyctereutes procyonoides in Białowieża Primeval Forest (E Poland) in 1997-2002, we addressed the hypothesis that pattern of shelter use by this invasive carnivore is an adaptation to both climatic conditions and predation. Raccoon dogs used various types of shelters but were invariably concealed in dense vegetation or in the shelters created by trunks, branches, or roots of fallen trees (58% of days). Burrows (mainly badger setts) and hollow trees (mainly fallen limes) were selected on 27% and 14% of days, respectively. The pattern of shelter use varied throughout the year. In crucial periods (breeding period and winter), raccoon dogs used shelter offering better protection: burrows and hollow trees (use of which increased with decreasing ambient temperature) in winter, and hollow trees and dense vegetation during breeding and raising pups. The pattern of shelter use by raccoon dogs was also strongly modified by forest structure. Raccoon dogs living in the pristine old-growth stands (with large amounts of dead wood) utilized mainly natural shelters created by fallen trees (trunks, branches, and roots) and sedge tussocks (38% and 37%, respectively). Individuals inhabiting the managed part of the Forest used mainly burrows (43%) and thicket (23%). We recorded very strong monogamous relationships between pair mates, manifested by shared resting on 84% of days per year. We conclude that hiding behavior and plasticity in shelter use is a response to high mortality due to predation and to unfavorable climatic conditions. High adaptability to various environmental conditions may be one of the factors underlying successful range expansion of raccoon dogs in Europe.
