50-543: Along with the adjacent Iroquois National Wildlife Refuge to the east and the Oak Orchard Wildlife Management Area farther to the east, Tonawanda WMA contributes to a continuous 19,000-acre (77 km) region dedicated to conservation and wildlife management known as the Alabama Swamp Complex. Approximately 100,000 migratory birds pass through the area each year. The wildlife management area

100-434: A few feet deep and never occupied, but the numerous burrows gave the impression that groundhogs live in communities. Abandoned groundhog burrows benefit many other species by providing shelter. They are used by cottontail rabbits, raccoons, foxes, river otters, eastern chipmunks, and a wide variety of small mammals, snakes, and birds. Groundhogs are one of the few species that enter into true hibernation , and often build

150-400: A higher civilization. It cleans its face after the manner of the squirrels, and licks its fur after the manner of a cat. Your committee is too wise, however, to be deceived by this purely superficial observation of better habits. Contemporaneous with the ark, the woodchuck has not made any material progress in social science, and it is now too late to reform the wayward sinner. The average age of

200-451: A lot of woodchucks working over a lot of years to create tunnel systems that would pose any risk to a structure. The burrow is used for safety, retreat in bad weather, hibernating, sleeping, love nest, and nursery. In addition to the nest, there is an excrement chamber. The hibernation or nest chamber is lined with dead leaves and dried grasses. The nest chamber may be about twenty inches to three feet (51–91 cm) below ground surface. It

250-503: A permit. Except for Bartel Road and Meadville Road, both of which pass through the WMA, all other roads are unpaved and reserved for official use. Pedestrian traffic in the WMA uses these roads and other paths along the dikes, which divides the WMA into separate marshes. Two observation areas with ample parking and public information are located along Lewiston Road. Iroquois National Wildlife Refuge The Iroquois National Wildlife Refuge

300-413: A pound of vegetation daily. In early June, woodchucks' metabolism slows, and while their food intake decreases, their weight increases by as much as 100% as they produce fat deposits to sustain them during hibernation and late winter. Instead of storing food, groundhogs stuff themselves to survive the winter without eating. Thought not to drink water, groundhogs are reported to obtain needed liquids from

350-442: A separate "winter burrow" for this purpose. This burrow is usually in a wooded or brushy area and is dug below the frost line and remains at a stable temperature well above freezing during the winter months. In most areas, groundhogs hibernate from October to March or April, but in more temperate areas, they may hibernate as little as three months. Groundhogs hibernate longer in northern latitudes than southern latitudes. To survive

400-577: A variety of other animals. All three areas constitute the Alabama Swamp Complex. Iroquois National Wildlife Refuge is managed by the U.S. Fish and Wildlife Service while Oak Orchard and Tonawanda Wildlife Management Areas are managed by the New York State Department of Environmental Conservation . The 10,828-acre (43.82 km ) refuge encompasses several large pools (separated by dikes ), swamps , meadows, fields, and woodlands . There are four overlooks and four trails that are open throughout

450-630: A woodchuck may die from infestation or from bacteria transmitted by vectors. In areas of intensive agriculture and the dairying regions of the state of Wisconsin, particularly in southern areas, the woodchuck had been almost extirpated by 1950. Jackson (1961) suggested that exaggerated reports of damage done by the woodchuck led to excessive culling, substantially reducing its numbers in the state. In some areas woodchucks are important game animals and are killed regularly for sport, food, or fur. In Kentucky, an estimated 267,500 M. monax were taken annually from 1964 to 1971. Woodchucks had protected status in

500-827: Is a wildlife refuge in Genesee and Orleans counties in western New York . The refuge is located between the cities of Buffalo and Rochester and is operated by the United States Fish and Wildlife Service . The refuge headquarters and visitor center are located at 1101 Casey Road in Alabama, New York . The Orleans County portion of the refuge lies in the town of Shelby . Mammalian species that inhabit this refuge include white-tailed deer , species of squirrel , porcupine , muskrat , raccoon , coyote , skunk , beaver , species of chipmunk , river otter , two species of fox , bobcat , mink , opossum and woodchuck . The refuge

550-436: Is about 16 inches (41 cm) wide and 14 inches (36 cm) high. There are typically two burrow openings or holes. One is the main entrance, the other a spy hole. Description of the length of the burrow often includes side galleries. Excluding side galleries, Schoonmaker reports the longest was 24 feet (7.3 m), and the average length of eleven dens was 14 feet (4.3 m). W. H. Fisher investigated nine burrows, finding

600-502: Is common to see one or more nearly motionless individuals standing erect on their hind feet watching for danger. When alarmed, they use a high-pitched whistle to warn the rest of the colony, hence the name "whistle-pig". Groundhogs may squeal when fighting, seriously injured, or caught by a predator. Other vocalizations include low barks and a sound produced by grinding their teeth. David P. Barash wrote that he witnessed only two occasions of upright play-fighting among woodchucks and that

650-518: Is located in a swampy area that has historically been a stopping point for migratory wildfowl. The area was hunted by Native Americans and early settlers. The land was purchased by New York State to protect the wildlife from over-hunting using funds from duck stamps and taxes on firearms and ammunition. The stated objectives of the WMA are increased waterfowl production, waterfowl protection, and flood control. Tonawanda WMA lies about halfway between Buffalo and Rochester . It lies halfway between

700-414: Is open to pedestrians year round. The eastern half of the refuge contains a scattering of smaller pools, many marshy areas, fields, and upland forests. The Swallow Hollow Trail (a 1.3-mile [2.1 km] loop) is located at the eastern edge of the refuge on Knowlesville Road and circles Swallow Hollow Marsh. The Onondaga Trail (1.2 miles [1.9 km] one way) is located off Sour Springs Road and passes along

750-762: Is shorter than that of other Sciuridae—only about one-fourth of body length. The groundhog dwells in lowland habitats, unlike other marmots that live in rocky and mountainous areas. Marmota monax has a wide geographic range. The groundhog prefers open country and the edges of woodland, being rarely found far from a burrow entrance. It can typically be found in small woodlots, low-elevation forests, fields and pastures, and hedgerows. It constructs dens in well-drained soil, and most groundhogs have summer and winter dens. Human activity has increased food access and abundance, allowing M. monax to thrive. W.J. Schoonmaker reports that groundhogs may hide when they see, smell, or hear an observer. Marmot researcher Ken Armitage states that

800-522: The Village of Akron to the south and the Village of Middleport to the north. The Tonawanda WMA consists of 5,600 acres (23 km), consisting primarily of wetlands. The WMA is on a floodplain of the Tonawanda Creek . Water retention is facilitated by impoundments, which increase wetland area and control flooding in nearby inhabited areas. NY Route 77 , Lewiston Road, passes through the north part of

850-494: The woodchuck , is a rodent of the family Sciuridae , belonging to the group of large ground squirrels known as marmots . A lowland creature of North America, it is found through much of the Eastern United States , across Canada and into Alaska . It was first scientifically described by Carl Linnaeus in 1758. The groundhog plays an important role maintaining healthy soil in woodlands and plains ; as such,

900-608: The Spring. Beyond their large size, groundhogs have several successful anti-predator behaviors, usually retreating to the safety of their burrow which most predators will not attempt to enter, but also being ready to defend themselves with their sharp claws and large incisors. They can also scale trees to escape a threat. Both their diet and their habit of burrowing make groundhogs serious nuisance animals around farms and gardens. They will eat many commonly grown vegetables. Extensive burrowing can undermine foundations. Very often,

950-685: The WMA. The south boundary of part of Tonawanda WMA is the Tonawanda Indian Reservation . The WMA is located adjacent to the Iroquois National Wildlife Refuge and the Oak Orchard Wildlife Management Area , both located east of the Tonawanda WMA. Located several miles north is the 401-acre (162 ha) Hartland Swamp Wildlife Management Area in the Town of Hartland . The former John White Memorial Game Farm, located south of

1000-568: The accompanying bill be passed." Groundhogs may be raised in captivity, but their aggressive nature can pose problems. Doug Schwartz, a zookeeper and groundhog trainer at the Staten Island Zoo , has been quoted as saying "They're known for their aggression, so you're starting from a hard place. His natural impulse is to kill 'em all and let God sort 'em out . You have to work to produce the sweet and cuddly." Groundhogs cared for in wildlife rehabilitation that survive but cannot be returned to

1050-451: The annual Groundhog Day ceremony. Famous Southern groundhogs include General Beauregard Lee , based at Dauset Trails Nature Center outside Atlanta, Georgia . Groundhogs are used in medical research on hepatitis B -induced liver cancer . A percentage of the woodchuck population is infected with the woodchuck hepatitis virus (WHV), which is similar to human hepatitis B virus. Humans cannot contract hepatitis from woodchucks with WHV, but

1100-404: The community of Alabama on NY-77 at the junction with NY-63 , is also available for public use. Hunting, fishing, hiking, bird watching and snowshoeing is permitted at Tonawanda WMA. Trapping is also allowed via permits assigned by lottery. Prohibited activities include the use of motorized vehicles (except in parking areas), and the use of motorized boats. Camping is available only to groups with

1150-399: The deepest point 49 inches (120 cm) down. The longest, including side galleries, was 47 ft 11.5 in (14.62 m). Numbers of burrows per individual groundhog decrease with urbanization . Bachman mentioned that when the young groundhogs are a few months old, they prepare for separation, digging a number of holes in the area of their early home. Some of these holes were only

1200-406: The dens of groundhogs provide homes for other animals, including skunks, red foxes, and cottontail rabbits. Foxes and skunks feed upon field mice, grasshoppers, beetles, and other creatures that destroy farm crops. In aiding these animals, the groundhog indirectly helps the farmer. In addition to providing homes for itself and other animals, the groundhog aids in soil improvement by bringing subsoil to

1250-432: The first two or three years, after which weight plateaus. Groundhogs have four incisors , which grow 1.5 millimetres ( 1 ⁄ 16  in) per week. Constant usage wears them down by about that much each week. Unlike the incisors of many other rodents, the incisors of groundhogs are white to ivory-white. Groundhogs are well-adapted for digging, with powerful, short legs and broad, long claws. The groundhog's tail

1300-622: The hibernation patterns of groundhogs may lead to benefits for humans, including lowering of the heart rate in complicated surgical procedures. Groundhog burrows have revealed at least two archaeological sites , the Ufferman Site in the U.S. state of Ohio and Meadowcroft Rockshelter in Pennsylvania . Archaeologists have never excavated the Ufferman Site, but the activities of local groundhogs have revealed numerous artifacts . They favor

1350-513: The juices of food-plants, aided by their sprinkling with rain or dew. Groundhogs are excellent burrowers, using burrows for sleeping, rearing young, and hibernating . Groundhog burrows usually have two to five entrances, providing groundhogs their primary means of escape from predators. The volume of earth removed from groundhog burrows in one study averaged 6 cubic feet (0.17 m ) per den. The longest burrow measured 24 feet (7.3 m) plus two short side galleries. Though groundhogs are

1400-567: The larger number scatter, to burrow on their own. In the wild, groundhogs can live up to six years with two or three being the average life expectancy. In captivity, groundhogs reportedly live up to 14 years. Human development often leaves vacant space near secondary forests , which are indigenous to groundhogs, which ensures that groundhogs in well-developed areas are nearly free of predators other than humans (through various forms of pest control or roadkills) or mid-to-large sized dogs . Occasionally, woodchucks may suffer from parasitism , and

1450-537: The latter being the third most significant prey species per a statewide study in Pennsylvania . Large predators such as gray wolf and eastern cougar are likely extirpated in the east but still may hunt groundhogs on occasion in Canada . Golden eagles can also prey on adult groundhogs, but seldom occur in the same range or in the same habitats as this marmot. Likewise, great horned owls can reportedly, per Bent (1938), prey upon groundhogs but rarely do so, given

1500-490: The most solitary of the marmots, several individuals may occupy the same burrow. Burrows can pose a serious threat to agricultural and residential development by damaging farm machinery and even undermining building foundations. In a June 7, 2009, Humane Society of the United States article, "How to Humanely Chuck a Woodchuck Out of Your Yard" by John Griffin, director of Humane Wildlife Services, stated you would have to have

1550-462: The north side of Onondaga Pool into a mature woods. The wetlands are watered by Oak Orchard Creek . New York State Route 63 is a north-south highway passing through the center of the refuge. Iroquois National Wildlife Refuge allows hiking, cross-country skiing, snowshoeing, nature observation, and photography. Non-motorized boats may be used on Oak Orchard Creek between Knowlesville Road and NY-63. Bicycles are permitted only on public roads within

1600-482: The refuge is divided into four large wetlands: Cayuga Pool, Mohawk Pool, Oneida Pool, and Seneca Pool. The Feeder Road, an unpaved north-south road, separates the Seneca and Cayuga pools from the other two. Cayuga Pool off of Route 77 has an observation platform in the parking lot. Kanyoo Trail, located nearby to the east, has two loops (0.33 and 1 mile [0.53 and 1.61 km] long). Feeder Road (3.5 miles [5.6 km] one way)

1650-709: The refuge. Hunting, fishing and trapping are allowed in-season with the proper permits. Prohibited activities include camping, disturbing historical artifacts, swimming, fires, removing wildlife and plants, horseback riding and off-road vehicle use, and carrying firearms except during hunting season (with permit). The Iroquois Job Corps is located within Iroquois National Wildlife Refuge at 11780 Tibbets Road in Medina. Groundhog Mus monax Linnaeus, 1758 Arctomys monax (Linnaeus, 1758) The groundhog ( Marmota monax ), also known as

1700-595: The social biology of the groundhog is poorly studied. Despite their heavy-bodied appearance, groundhogs are accomplished swimmers and occasionally climb trees when escaping predators or when they want to survey their surroundings. They prefer to retreat to their burrows when threatened; if the burrow is invaded, the groundhog tenaciously defends itself with its two large incisors and front claws. Groundhogs are generally agonistic and territorial toward conspecifics and may skirmish to establish dominance. Outside their burrow, individuals are alert when not actively feeding. It

1750-648: The species is considered a crucial habitat engineer . The groundhog is an extremely intelligent animal, forming complex social networks and capable of understanding social behavior , forming kinship with its young, understanding and communicating threats through whistling , and working cooperatively to solve tasks such as burrowing . Common names for the groundhog include chuck , wood-shock , groundpig , whistle-pig , whistler , thickwood badger , Canada marmot , monax , moonack , weenusk , red monk , land beaver , and, among French Canadians in eastern Canada , siffleux . The name "thickwood badger"

1800-560: The state of Wisconsin until 2017. Woodchuck numbers appear to have decreased in Illinois. Wild predators of adult groundhogs in most of eastern North America include coyotes , badgers , bobcats , and foxes (largely red fox ). Many of these predators are successful stealth stalkers that catch groundhogs by surprise before they can escape to their burrows; badgers likely hunt them by digging them out from their burrows. Coyotes in particular are sizable enough to overpower any groundhog with

1850-488: The surface. The groundhog is also a valuable game animal and is considered a difficult sport when hunted in a fair manner. In some parts of the U.S., they have been eaten. A report in 1883 by the New Hampshire Legislative Woodchuck Committee describes the groundhog's objectionable character: The woodchuck, despite its deformities both of mind and body, possesses some of the amenities of

1900-462: The temporal differences in their behaviors. Young groundhogs (usually those less than a couple months in age) may also be taken by the American mink , and perhaps other small mustelids , cats , timber rattlesnakes , and hawks . Red-tailed hawks can take groundhogs at least of up to the size of yearling juveniles, and northern goshawks can take them up to perhaps weak emergent-adult groundhogs in

1950-1015: The upright posture of play-fighting involves sustained physical contact between individuals that may require a degree of social tolerance virtually unknown in M. monax . Alternatively, upright play-fighting may be a part of the woodchuck's behavioral repertoire that rarely is shown because of physical spacing and/or low social tolerance. Mostly herbivorous , groundhogs eat primarily wild grasses and other vegetation, including berries, bark, leaves, and agricultural crops, when available. In early spring, dandelion and coltsfoot are important groundhog food items. Some additional foods include sheep sorrel , timothy-grass , buttercup , persicaria , agrimony , red and black raspberries, mulberries, buckwheat, plantain, wild lettuce, all varieties of clover, and alfalfa. Groundhogs also occasionally eat small animals, such as grubs , grasshoppers , snails , and even bird eggs and baby birds, but are not as omnivorous as many other Sciuridae . An adult groundhog can eat more than

2000-486: The virus and its effects on the liver make the woodchuck the best available animal for the study of viral hepatitis in humans. The only other animal model for hepatitis B virus studies is the chimpanzee, an endangered species. Woodchucks are also used in biomedical research investigating metabolic function , obesity , energy balance , the endocrine system , reproduction , neurology , cardiovascular disease , cerebrovascular disease , and neoplastic disease . Researching

2050-583: The warmer spring weather produces abundant plant materials for food. Males emerge from hibernation before females. Groundhogs are mostly diurnal and are often active early in the morning or late afternoon. Groundhogs are considered the most solitary of the marmot species . They live in aggregations, and their social organization also varies across populations . Groundhogs do not form stable, long-term pair-bonds, and during mating season male-female interactions are limited to copulation . In Ohio , adult males and females associate with each other throughout

2100-813: The wild may remain with their caregivers and become educational ambassadors. In the United States and Canada, the yearly Groundhog Day celebration on February 2 has given the groundhog recognition and popularity. The most popularly known of these groundhogs are Punxsutawney Phil , Wiarton Willie , Shubenacadie Sam , Jimmy the Groundhog, Dunkirk Dave , and Staten Island Chuck kept as part of Groundhog Day festivities in Punxsutawney, Pennsylvania ; Wiarton, Ontario ; Sun Prairie, Wisconsin ; Dunkirk, New York ; and Staten Island respectively. The 1993 comedy film Groundhog Day references several events related to Groundhog Day, and portrays both Punxsutawney Phil himself, and

2150-525: The winter, they are at their maximum weight shortly before entering hibernation. When the groundhog enters hibernation, there is a drop in body temperature to as low as 35 degrees Fahrenheit (2 °C), heart rate falls to 4–10 beats per minute and breathing rate falls to one breath every six minutes. During hibernation, they experience periods of torpor and arousal. Hibernating woodchucks lose as much as half their body weight by February. They emerge from hibernation with some remaining body fat to live on until

2200-449: The woodchuck is too long to please your committee.... The woodchuck is not only a nuisance, but also a bore. It burrows beneath the soil, and then chuckles to see a mowing machine, man and all, slump into one of these holes and disappear.... The committee concludes that, "a small bounty will prove of incalculable good; at all events, even as an experiment, it is certainly worth trying; therefore your committee would respectfully recommend that

2250-1327: The words has led to the popular tongue-twister : The groundhog is by far the largest sciurid in its geographical range, except in British Columbia where its range may abut that of its somewhat larger cousin, the hoary marmot . Adults may measure from 41.8 to 68.5 cm ( 16 + 7 ⁄ 16 to 26 + 15 ⁄ 16  in) in total length, including a tail of 9.5 to 18.7 cm ( 3 + 3 ⁄ 4 to 7 + 3 ⁄ 8  in). Weights of adult groundhogs typically fall between 2 and 6.3 kg (4 lb 7 oz and 13 lb 14 oz). Male groundhogs are slightly larger than females on average and, like all marmots, they are considerably heavier during autumn (when engaged in autumn hyperphagia ) than when they emerge from hibernation in spring. Adult males average year-around weight 3.83 kg (8 lb 7 oz), with spring to fall average weights of 3.1 to 5.07 kg (6 lb 13 oz to 11 lb 3 oz) while females average 3.53 kg (7 lb 13 oz), with spring to fall averages of 3.08 to 4.8 kg (6 lb 13 oz to 10 lb 9 oz). Seasonal weight changes reflect circannual deposition and use of fat. Groundhogs attain progressively higher weights each year for

2300-443: The year and often from year to year. Usually groundhogs breed in their second year, but a small proportion may breed in their first. The breeding season extends from early March to mid- or late April, after hibernation. Woodchucks are polygynous but only alpine and woodchuck marmot females have been shown to mate with multiple males. A mated pair remains in the same den throughout the 31- to 32-day gestation period . As birth of

2350-416: The year. All areas of the refuge, except the nature trails, overlooks, and fishing areas, are closed from March 1 to October 1 to protect nesting birds and other wildlife. Each year at least one of the large pools is drained to allow restoration of the wetland. The refuge has been designated as an important bird area (IBA) because it is a key resting spot for birds when they are migrating. The western half of

2400-475: The young approaches in April or May, the male leaves the den. One litter is produced annually. Female woodchucks give birth to one to nine offspring, with most litters ranging between 3 and 5 pups. Groundhog mothers introduce their young to the wild once their fur is grown in and they can see. At this time, if at all, the father groundhog comes back to the family. By the end of August, the family breaks up; or at least,

2450-650: Was created in 1958 as the Oak Orchard National Wildlife Refuge , however the name was soon changed to avoid confusion with the similarly named Oak Orchard Wildlife Management Area , a state-owned conservation area adjacent to the federal refuge at its eastern boundary. Both areas, along with the Tonawanda Wildlife Management Area , located on the western side of the federal land, are used not only as stopping points for waterfowl and other migratory birds, but also to provide habitat for

2500-490: Was given in the Northwest to distinguish the animal from the prairie badger . Monax ( Móonack ) is an Algonquian name of the woodchuck, which means "digger" (cf. Lenape monachgeu ). Young groundhogs may be called chucklings. The etymology of the name woodchuck is unrelated to wood or any sense of chucking . It stems from an Algonquian (possibly Narragansett ) name for the animal, wuchak . The similarity between
