The European polecat is a seasonal breeder, with no courtship rituals. Between-sex dietary differences have been observed in some mustelids (McDonald 2002). (2) They may even prey on smaller mustelids such as the least weasel. Analysis of changes in polecat diets over time indicated that the occurrence of all mammals more than doubled between the 1960s (35%) and the 1980s (74%), after which the occurrence of mammals stabilised as a proportion of diet (Table 3). There was no significant difference between males and female polecats in FO of all mammals (including lagomorphs and other mammals), birds or amphibians. The common ferret (Mustela putorius furo) is a domesticated form of the European polecat, which it resembles in size and habits and with which it interbreeds.The common ferret differs in having yellowish white (sometimes brown) fur and pinkish red eyes. First, rabbits Oryctolagus cuniculus, which are important prey for polecats, have experienced extreme population fluctuations, with near extirpation due to myxomatosis in the 1950s, recovery in 1960s–1990s and declines in 1990s–2010s.

This means that the difference between frequency of occurrence calculated using total prey items or that using the number of stomachs is negligible (in this study, of the 99 polecat stomachs investigated and 79 that had identifiable contents, only three individual stomachs contained more than one item).

To view a copy of this licence, visit Whilst some dietary studies have correlated amphibian consumption to periods of abundance (Lodé 2000), others have found that polecats eat them preferentially (Weber 1989b). Some of the data collected historically was from stomach contents (Walton 1968; Birks and Kitchener 1999) and some from scat analyses (Blandford 1986), which created a potential source of sampling bias. Animals were stored frozen until necropsy examination, which was carried out at National Museums Scotland. European polecat diet. Basic Appl Ecol 12:116–124, Futuyma DJ, Moreno G (1988) The evolution of ecological specialization. Rodents were a common component of the diet … 1977; Perry and Pianka 1997), which may be maximised via different foraging strategies. BTO research report number 706. Following nineteenth-century declines, polecats Mustela putorius are recolonising Great Britain. Acta Theriol 49:337–347, Harris SJ, Massimino D, Gillings S, Eaton MA, Noble DG, Balmer DE, Procter D, Pearce-Higgins JW, Woodcock P (2018) The Breeding Bird Survey 2017. Its diet is based on rabbits, rodents, amphibians, eggs, birds and insects. The common ferret is also slightly smaller than the polecat, averaging 51 cm (20 inches) in length, including the 13-cm tail. Biometrics 33:159–174, CAS  Despite their reputation as pests of poultry, polecats eat small rodents, frogs, birds and snakes during their nocturnal hunting forays. Identifiable macroscopic animal remains (undigested body parts, fragments of bone, feathers, fur, individual hair and insect remains) were separated from unidentifiable tissues. Amphibians were determined by skin texture and, where possible, by webbing on feet (Inns 2011). In large river floodlands, water vole are common prey. In large river floodlands, water vole are common prey. The species doesn’t conform to Bergmann’s rule, with the sample of dimension variation seeming to observe the development of dimension improve alongside an east-west axis. Plant debris was considered to have been ingested when catching prey (Walton 1968) and was not included in diet composition quantification.

PLoS One 11:e0161943, Pyke GH, Pulliam HR, Charnov EL (1977) Optimal foraging: a selective review of theory and tests. Rodents are thought to be the major route by which polecats are exposed to second-generation anticoagulant rodenticides (SGARs) in Britain (Shore et al. A case study on two cyprinid fish in southern France. Polecats eat a wide variety of food items across their European range and are usually described as generalist predators (Erlinge 1986; Lodé 1995; Baghli et al. Evol Appl 1:427–448, PubMed  In Białowieża National Park, Poland, frogs comprised 60% and 90% of polecat total food biomass in summer and winter, respectively, and although polecats ate rodents, this was only when frogs were not available (Jędrzejewska and Jędrzejewska 1998). They live on a diversified meal. 2018). Mammal Rev 21:97–122, Rosecchi E, Thomas F, Crivelli AJ (2001) Can life-history traits predict the fate of introduced species? Mammal remains were identified to species level, except for rabbits and brown hares Lepus europaeus, which were not separated and were classified as lagomorphs. As of 2008, it’s classed by the IUCN as Least Concern resulting from its wide selection and enormous numbers. Domesticated Arctic Fox – Can There Be a Pet Fox? The European polecat's diet consists of mouse-like rodents, followed by amphibians and birds. Your email address will not be published. In ferret: Common ferret …a domesticated form of the European polecat, which it resembles in size and habits and with which it interbreeds.The common ferret differs in having yellowish white (sometimes brown) fur and pinkish red eyes. It may be that this increase has been a result of an increase in the proportion of rodents in polecat diet. 2000). MSc dissertation, Durham University, Durham, UK, Weber D (1989a) The diet of polecats (Mustela putorius L.) in Switzerland. Weaning begins at three weeks of age, whereas the everlasting dentition erupts after 7–8 weeks. McDonald et al. 2011; Aebischer 2019), but since then, rabbit numbers have declined across Britain (England − 44%; Scotland − 82%; and Wales − 48%; Harris et al. 2000), usually only have one prey item per stomach (e.g. Although they are present across Wales, much of England and parts of Scotland, polecats are elusive and rarely seen. This left 79 stomachs containing identifiable prey items (54 male, 24 female, 1 unknown). 2). Springer international publishing AG, Cham, Walton KC (1968) Studies on the biology of the polecat, Putorius Putorius (L). Biol Conserv 85:233–240, Birks JDS, Kitchener AC (1999) The distribution and status of the polecat Mustela putorius in Britain in the late 1990s. The natural diet of the European polecat ferret consists of whole small prey, i.e., meat, organs, bones, skin, feathers, and fur. 2018), unlike the 1950s myxomatosis epizootic (Sumption and Flowerdew 1985), and so, polecats have still been able to find and take rabbits as their major prey item. The polecat is an effective swimmer, however, its fur isn’t as properly insulated in opposition to chilly water as the polecat cools down at 26–28 minutes. In winter, the polecat could use farm buildings or haystacks as daytime resting places. Comparisons between stomach and intestinal content of stoats (Mustela erminea: Day 1968; M. e. cicognanii: Aldous and Manweiler 1942) and common weasels Mustela nivalis (Day 1968) found no difference between stomach and intestinal content analysis in terms of dietary reconstruction, and therefore, it was considered acceptable to compare polecat diets between all of the historical studies. The level of overlap in identification indicated that identification of guard hair was sufficiently robust for inclusion in our data analysis. At delivery, the kits weigh 9-10 g and measure 55–70 mm in body size; they’re blind, naked, and deaf.
