In many languages, raccoons are named after their “washing” behavior. Our low level of parentage assignment prohibited attempts to analyze the effect of group membership on paternity. A pair of raccoons walking down a sidewalk may feel provoked if you are coming towards them on the same sidewalk. 2000) were cloned from kinkajous (Potos flavus). The reason is simple, cities provide far more food, shelter and potential mates in a smaller geographical area so the need to travel great distances just isn’t there. Spatial distribution.—Twelve males and 15 females were fitted with proximity-detecting collars whose very-high–frequency transmitters were working during winter. The family unit breaks up with the new mating season. The mean (± SD) number of alleles per locus was 12.6 ± 5.5 (range 4–24), mean expected heterozygosity was 0.79 ± 0.14 (range 0.45–0.90), and the mean polymorphic information content was 0.768 ± 0.150 (range 0.349–0.894; Table 1). We used a similar protocol to periodically recapture raccoons to download data from their radiocollars (see below) through July 2006. Additional funding was provided by Cook County Animal Control and the Max McGraw Wildlife Foundation. For example, when the territory of a lone male overlaps with several females a system of polygyny is presumed. Of 8 group males only 3 were assigned as fathers to sampled offspring. However, none of the parents identified through genetic analysis denned together during this period; therefore, den sharing is not a requirement for mating success. However, among the remainder of the adult population, we found a sharp increase in instances of den sharing between unrelated adults that coincided with the peak of the mating season. Properly secure all garbage and food waste to deter raccoons from hanging around your home or property. However, parentage assignment was not distributed equally among males and females, because juveniles were twice as often assigned to resident females as they were to resident males. Nine weeks later, females give birth to 2-5 young.

During the three to four days in which conception is on the table, raccoons will meet as a social group, foreplay and copulation being repeated during these nights, with sessions that last for about an hour. We were unable to identify parents for 25 of 43 juveniles, which greatly reduced our ability to assess the raccoon mating system. It has a bushy, ringed tail and black paws with five toes. When new adults were captured in the study area following the initial trapping period these animals—6 males (M) and 8 females (F)—were ear-tagged and sampled for genetic analysis as described above. This website uses cookies to improve your experience while you navigate through the website. During a harsh winter, a group of raccoons may band together. Keep raccoons out of the house. Males do not assist in rearing young and may kill any young encountered. When we excluded juveniles from genetic analysis we found that 6 new loci combinations were significantly linked, but none of the previous 3 loci were in linkage disequilibrium. 95% CI = 95% confidence interval. Parentage analyses.—We were unable to identify either parent for 25 (58.1%) of 43 juveniles sampled. Proudly serving: Ottawa, Montreal, Halifax, Hamilton, Burlington, Oakville, Mississauga, Brampton, Kitchener-Waterloo, Guelph, Sudbury, St. Catharines, Cambridge and the Niagara Region. Because of the likelihood that 1-s contacts may occur spuriously or represent contacts beyond the preset contact distance (Prange et al. These 18 juveniles were assigned to 10 unique mothers (8 radiocollared females, 4 with functioning collars during the winter), and 12 were assigned to 7 unique fathers (4 radiocollared, all of which were functioning during winter). The preserve is used by visitors primarily for picnicking; uncovered garbage receptacles give raccoons easy access to refuse for the 8 months of the year (April-November) that the preserve is open to the public, leading to high population densities within the reserve (75 raccoons/km2—Prange et al. An adult raccoon can shred a dog's skin in a second. Tanuki are nocturnal, and spend most of their time foraging at night. Kitchen A. M. Gese E. M. Waits L. P. Karki S. M. Schauster E. R..

Anchor and the Cook County Forest Preserve District for additional support and access to the study site. We found that 3 of 4 parent pairs shared >35% of their daytime resting areas and >26% of their core resting areas. 2). 2008) and are believed to form breeding hierarchies within these groups (Gehrt and Fritzell 1999). Water is thought to increase their sense of touch as well. Raccoons are smarter than cats but less smart than monkeys. Dwyer et al. High raccoon densities may underlie the high rate of multiple paternity in our study population, because the overall raccoon density within our study site (75 raccoons/km2—Prange et al. The mother carries the young one around its neck to come out from the den, similar to a cat carrying a kitten. Parent pairs were not observed to share dens during the mating season. We placed traps baited with commercial cat food within the core trapping area during May 2004. The raccoon is a medium-sized woods mammal ... only captive raccoons exhibit food-dousing behavior, scientists believe that washing food is simply a substitute for normal ... after mating and until babies are born and may help rear the young. They are most active in spring, summer and fall, and will sleep in their dens for most of the winter. Often, these mating systems are inferred from spatial relationships during the breeding season (Ralls et al. Previously marked individuals were released without handling. Polymerase chain reaction products were screened using a Beckman–Coulter CEQ 8000XL automated capillary genotyp-ing system (Beckman-Coulter, Inc.), and allele sizes were determined using Genetic Analysis System Software, version 8.0 (Beckman-Coulter, Inc.). Adults were distinguished from juveniles by reproductive condition (e.g., lactation—Sanderson and Nalbandov 1973) and patterns of tooth eruption and wear (Grau et al. The word ‘raccoon’ is […] Thirty-one MF dyads denned together at least once during the mating season and most dyads (n = 23) denned together more than once, yielding a total of 180 den-sharing events. Split, Scram, Scoot! Finally, we examined the relationship between parentage and den sharing. It seems likely that because males are unable to secure access to multiple females with short and synchronized estrous periods, particularly in high-density environments, males might rely on mutual tolerance to reduce effort and injury due to male-male competition (Olson and Blumstein 2009). Roaming during the peak mating period by solitary adult males has been observed for raccoons (Gehrt and Fritzell 1998) and might be a more common strategy among males than previously realized. Females, on the other hand, will faithfully stay with their young until the end of their first winter. Proportion (+ confidence limit) of daytime resting areas (DRAs) and core resting areas (CRAs) for female-female (FF), male-female (MF), nongroup male (MM-NG), and group male (MM-G) radiocollared raccoons during the breeding season (1 December 2004-31 March 2005) in Ned Brown Forest Preserve in northeastern Illinois. Two of 3 males that were assigned more than 1 offspring mated with more than 1 female. They head straight for the nearest food source. Based on our data, we suggest that the mating system in our study population represents genetic promiscuity. What are raccoons' mating habits? Loci used for parentage analysis, number of alleles per locus (N), polymorphic information content (PIC), expected heterozygosity (HE), observed heterozygosity (HO), frequency of null alleles (F(Null)), and deviation from Hardy-Weinberg equilibrium (HW) by locus. For this study we focused on obtaining spatial locations for adult raccoons during the mating season (December 2004–February 2005). For both daytime resting area and core resting area coefficients of overlap were generally low within each dyad type (Fig. They breed during September and November. (1985) estimated that more than 1.5 million people visit the park annually, and at least as many visitors attended the park during our fieldwork (C. Anchor, Forest Preserve District of Cook County, pers. Basic information about the general habitat, diet, biology and mating habits of raccoons. Raccoon Biology, Diet, Habitat, Mating Habits Education about raccoons, procyon lotor, both urban and wild. Raccoons are wild animals, and they behave as such. This is seen quite often in urban environments and during the birthing season when mother raccoons are forced to change their habits when babies arrive. Just about anyone who has walked along the banks of our streams, rivers, and lakes has seen the hand-shaped tracks of the raccoon. @ A 4 • Mid-sized carnivore (omnivore) • Nocturnal • Semi-arboreal • Wide spread and common in North America ! comm.)

Once you know more about the raccoon, it becomes much easier to figure out ways of deterring them from moving into your property. They are social animals, and will remain in pairs or small groups. Incidents of den sharing of closely (1st- and 2nd-order) related dyads (n = 6) and unrelated dyads (n = 23) as determined by proximity-detecting radiocollars between adult male and female raccoons during the breeding season (1 December 2004-31 March 2005) in Ned Brown Forest Preserve in northeastern Illinois. At sunrise, tired raccoons find dens to sleep in for a long day’s rest. But opting out of some of these cookies may have an effect on your browsing experience. Its grayish coat mostly consists of dense underfur which insulates it against cold weather. Reproduction. 1-888-592-0387. We observed a sharp increase in den-sharing incidents between unrelated individuals that coincided with the peak of the mating season, observations that are consistent with consortship behavior (Gehrt and Fritzell 1999). Each proximity-detecting collar was capable of simultaneously recording contacts with up to 8 others at any given time. 2003) was much higher than typical rural populations (Gehrt 2003). 2006]). 1991). The fingers are also spaced far apart. In addition to generating new insights into the mating system of our study species, our findings suggest that in raccoons spatial relationships among adults do not provide consistent predictors of genetic parentage. Raccoon Habit #7 Special Hands. 2008) or coalitions (Pitt et al. Thus, in species in which males live in social groups or coalitions, it is critical to understand how spatiosocial interactions translate into reproductive success. Studies have shown that in urban settings raccoons generally limit their movements to a smaller range than their cousins in the country. Raccoon dogs use vocalizations to communicate with each other. Relatedness between radiocollared parents was low, with mean r = -0.027 ± 0.086 (n = 10 parent pairs; range -0.132–0.072). School of Natural Resources, Ohio State University, 2021 Coffey Road, Columbus, OH 43210, USA. Male raccoons might form social groups (Gehrt and Fritzell 1998, 1999; Gehrt et al. Females usually give birth to 2-5 cubs after the gestation period that lasts around 63-65 days. Although females never mated with more than 1 group of males, females bred with group members, solitary resident males, and putative nonresident males. However, this assumption became less realistic over time as juveniles matured into adults, resident individuals died, and new adults immigrated. No parent was identified for any of the remaining 25 juveniles at ±80% confidence. As it feels around, it sometimes finds food. The best defense against raccoons invading your space is to know their habits and behaviors. We defined den sharing as contacts lasting longer than 4 h during the diurnal period and used the occurrence of this behavior as an additional measure of association between males. While raccoons don’t hibernate, those that live in cold climates sleep for long periods of time during winter. With “hands” like these, a raccoon can hold things almost as well as a monkey can. A male’s territory can range as far as 250 acres, a female’s is generally much smaller since she’s often busy caring for her young and can’t afford to wander off too far. It has a black mask around its eyes with white fur around the mask. Alternatively, nonresident males could have moved temporarily into the study site during the breeding season. Males in rural areas have been known to wander as far as 10 miles in search of food or a mate. All forward primers were fluorescently labeled with Well-Red fluorescent tags D3 or D4 (Beckman-Coulter, Inc., Fullerton, California). Our study was limited by our inability to sample offspring in natal dens, and we might have missed successful matings if juveniles were lost to mortality or dispersal prior to our fall trapping.
