The only area not to report this pattern of events, Zwanenwater, apparently proved the rule. He concluded, on circumstantial but consistent evidence, that the formerly abundant stoats were driven to extinction by foxes throughout the dunelands. Mulder searched the records, conducted interviews with the wardens, and plotted the acceleration in the recovery of the rabbits from myxomatosis throughout the 1970s and early 1980s. The detailed local knowledge of the wardens documented incidentally the unexpected disappearance of stoats from the dunelands from the mid- to late 1980s onward, following the arrival of foxes between 19. The wardens also assisted with several research projects on the stoat populations during the 1960s (Heitkamp & van der Schoot 1966 van Soest & van Bree 1970). The local game wardens knew their areas and the animals well, and they compiled field notes and annual reports on their activities. The North Sea coast of the Netherlands from Den Haag to Den Helder is lined with a strip of sand dunes up to 5 km wide, long famous for its rabbits and for the stoats, weasels, and polecats that hunted them. It seems logical to assume, concluded Latham, that foxes reduce and control the numbers of weasels in Pennsylvania.Ī single historical event observed and described in unusual detail by Mulder (1990) supports Latham's view. This inverse relationship was repeated in the relative numbers of foxes and of weasels killed in each county, as shown in Table 11.5. Between 19, the numbers of foxes went down again, which Latham attributed to the heavy toll from the bounty hunters at the same time, the weasels were apparently recovering. Then in the late 1930s and early 1940s, the number of weasels decreased, dropping below 20,000 by 1946, while the number of foxes over the same period increased to over 80,000 their relative proportions in the records became nearly reversed. In the early 1930s the total number of weasels killed per year was over 100,000, and of foxes, under 40,000. He examined the bounty records of the Pennsylvania Game Commission during the 1930s and 1940s, when hunters and trappers were paid to turn in dead foxes, both red and gray, and weasels of all three species. One of the earliest researchers who believed they do was Latham (1952). The question is, do these encounters happen often enough to affect the weasel populations? Weasels are believed to have somewhat distasteful flesh, so these predators do not necessarily eat a weasel once they have killed it, but that is hardly a comfort. Weasels of all species are small enough to be regarded as, or confused with, the normal prey of foxes, coyotes, feral cats, minks and ferrets, plus owls and hawks (Hellstedt & Kallio 2005). In addition, weasels suffer from more natural hazards, including intense persecution from larger predators. ![]() One unlucky, rain-soaked common weasel crawled into a railway signal box to get out of a storm, short-circuited all the signals, and stopped the trains (Anon. The active lifestyle of weasels and their insatiable curiosity about dark and inviting-looking holes make them vulnerable to sudden death in kill traps (Chapter 12) and other dangerous places. Stoats and longtails are often killed on the road, especially males in spring (Buchanan 1987 Sleeman 1988a). ![]() Why do most wild weasels achieve only a tenth or less of their potential life span? The most obvious explanation, considering that weasels are obligate predators dependent on wildly variable food supplies, is shortage of food, but there are others. Tame weasels of any species, well settled in captivity, can live up to 10 years. ![]()
