William H. Burt and Richard P. Grossehnheider. In 1980, an examination conducted on U.S. river otter populations determined they were locally extinct in 11 states, and lost significant population in 9 other states. River otters are omnivorous, eating mostly aquatic organisms, including fish, frogs, crayfish, turtles, insects and some small mammals. They were extirpated from portions of their range, but conservation and reintroduction efforts are helping populations to recover. HABITAT: To compare estimates of occupied area in 1998 with our survey results, we digitized published maps depicting river otter distribution during 1998 (Melquist et al. Found throughout the United States and Canada. A groundbreaking bipartisan bill aims to address the looming wildlife crisis before it's too late, while creating sorely needed jobs. VIDEO. Poorly known. They have been virtually eliminated through many parts of their range, especially around heavily populated areas in the midwestern and eastern United States. As a result, slow-swimming fish are consumed more often than game fishes when both are equally available. [23], Aquatic life ties North American river otters almost exclusively to permanent watersheds. [1] Otters have recently re-established themselves on Prince Edward Island. River Otters are good swimmers and divers, able to stay underwater for up to eight minutes. Water pollution and other diminution of aquatic and wetland habitats may limit distribution and pose long-term threats if the enforcement of water quality standards is not upheld. DESCRIPTION: Birmingham, AL 35223. They feed on crayfish, crabs, fish, birds, small mammals, and some aquatic plants. [54][57], Cases where otters have been ambushed and consumed by grizzly bears (Ursus arctos horribilis) and polar bears (Ursus maritimus) have also been reportedly witnessed near the Arctic region. Twenty-two states reported increasing populations while 25 reported stable populations. These include mudminnows (Umbra limi) and sculpins (Cottus spp.). LIFEHISTORY AND ECOLOGY: Found at DOI: https://doi.org/10.3996/102018-JFWM-093.S2 (38 KB XLSX). ), shiners (Notropis and Richardsonius spp. [1996], Roberts et al. Two states (Connecticut and Tennessee) reported that regulations are reviewed every 4 to 5 years. South Carolina and Texas reported that harvest regulations are never reviewed. However, it typically occurs in winter or spring. The North American River Otter weighs on average 10 to 30 pounds and measures approximately two to four feet long from head to tail. Continued monitoring of the population status and distribution at state and national levels would likely detect any significant changes should they occur.

Dodge also assisted with several aspects of this effort.We would also like to thank the Associate Editor and anonymous reviewers for constructive and value suggestions and comments that improved the quality of this manuscript. To protect fish in these cases, the otters may need to be removed or relocated. When river otter presence was unknown in a county, which could occur where there is no harvest or monitoring effort (i.e., arid or remote regions), we recorded presence in those counties as unknown.' At about two months they begin to venture out of the den to play and to learn how to swim and hunt. Even fast-swimming fish like trout slow down in extremely cold water, leaving them vulnerable. Now they are gone from the central and eastern United States, and extinct or rare in Arizona, Colorado, Indiana, Iowa, Kansas, Kentucky, Nebraska, New Mexico, North Dakota, Ohio, Oklahoma, South Dakota, Tennessee, Utah, and West Virginia. Assessments of river otter populations within the contiguous United States have occurred periodically since their inclusion in Convention on International Trade in Endangered Species of Wild Fauna and Flora (e.g., Polechla 1990, Raesly 2001, Melquist et al. We're on the ground in seven regions across the country, collaborating with 52 state and territory affiliates to reverse the crisis and ensure wildlife thrive. Life expectancy is less than 10 years in the wild. [16], North American river otters consume an extensive assortment of fish species ranging in size from 2 to 50 centimeters (0.79 to 19.69in) that impart sufficient caloric intake for a minute amount of energy expenditure. [49] However, large populations never occurred in areas of Southern California such as the chaparral and oak woodlands and Mojave Desert seasonal waterway regions, or in the xeric shrubland regions in New Mexico, Texas, Nevada, and Colorado. The North American river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. Other restoration efforts were conducted to bolster existing river otter populations and to expand otter distributions and provide connectivity within states that had existing, but not ubiquitous, river otter populations (Table 1). The den typically has many tunnel openings, one of which generally allows the otter to enter and exit the body of water. Read on to learn about the otter. North American river otters rely upon play to learn survival skills such as fighting and hunting. Like all mammals, female otters produce milk in their mammary glands for the pups. Based on this 2016 survey, 22 states reported increasing populations, 25 states reported stable populations, and 2 states (Arizona and Washington) reported an uncertain population trend (Table 1). Deems and Pursley (1978), estimated that river otters occupied 71% of their historical range during 1977; by 1998, river otter populations had expanded and were thought to occupy 90% of their prior range (Melquist et al. Junior League of Birmingham Hugh Kaul Childrens Zoo Alabama Wilds Trail. This kind of pollution could deplete the food supply for the otters. River otters were legally harvested in 40 states, while closed harvest seasons existed in 9 states; Arizona, California, Colorado, Nebraska, New Mexico, Rhode Island, South Dakota, Utah, and Wyoming (Table 1). Their legs are short with webbed feet and claws. We tallied responses to these questions and reported frequency of responses. Young are able to fully care for themselves at about six months of age but they do not usually leave their mother until about one year. Herein we provide an updated account, as of 2016, of river otter population status and distribution in the United States and discuss conservation priorities. [58][59][37][60], Threats to North American river otter populations in North America vary regionally. River Otters are good swimmers and divers, able to stay underwater for up to eight minutes. [34][50] Invertebrates discovered within scats or digestive tracts could most likely be a secondary food item, first being consumed by the fish that are subsequently preyed upon by the North American river otters. Otter pelts range from a rich dark brown (almost black) to a pale chestnut on the back and sides and light brown mixed with varying amounts of gray on the belly. Washington, D.C. 750 pp. Comparisons between our survey and published reports from 1998 (Melquist et al. The mammals have thick, protective fur to help them keep warm while swimming in cold waters. They can thrive in any water habitat, such as ponds, marshes, lakes, rivers, and estuariesin cold, warm, or even high-elevation areasas long as the habitat provides adequate food. A river otter can grow three to four feet (0.9 to 1.2 meters) long including its tail and weigh between 11 and 30 pounds (5 to 14 kilograms). The Smithsonian Book of North American Mammals. In many places, the populations have re-established themselves because of conservation initiatives. As populations have expanded, river otter reintroduction efforts have become less frequent; two additional states had conducted reintroductions since 1998 and only one state had conducted a reintroduction since 2010. River otter Lontra canadensis populations in the United States have expanded during the past 50 y as a result of improvements in habitat quality and effective management programs implemented by state and federal agencies and native tribes. Estimated range of river otters Lontra canadensis in the United States during 2016 compared with 1998 (estimated from Melquist et al. Based on maps published by Melquist et al. They are fast, agile swimmers and able to out-maneuver their prey. Methods of population monitoring included bridge surveys (presence vs. absence track surveys conducted at bridge crossings), harvest surveys, bowhunter surveys, camera surveys, winter track surveys, population models from harvest data, harvest effort, and agency field questionnaires (for detailed descriptions of these methods, we direct readers to Chilelli et al. In the past, their soft and attractive fur could be sold for a decent amount of money. Most states used multiple methods to monitor river otter populations including harvest-based surveys, presenceabsence surveys, and empirically derived population model predictions; harvest-based surveys were the most commonly used monitoring approach. 132 River Otters Playing Premium High Res Photos Browse 132 river otters playing stock photos and images available, or start a new search to explore more stock photos and images. Chanticleer Press, Inc. 937 pp. Journal of Fish and Wildlife Management 11(1):279286; e1944-687X. The tail makes up approximately 40 percent of the otters total length, which ranges from three to four-and-one-half feet. North American river otters can close their nostrils to keep water out during long dives. River otters can be found swimming all over in the state's creeks, lakes and ponds. Fish is a favored food among the otters, but they also consume various amphibians (such as salamanders and frogs[3]), freshwater clams, mussels, snails, small turtles and crayfish. [38][40], When left unchecked, though, otters can be significant predators under certain circumstances (e.g. [10] The North American river otter was first classified in the genus Lutra.

Crustaceans may even be consumed more than fish. According to WTMJ-TV, the Milwaukee County Zoo in Milwaukee shared the news . They can stay underwater for as many as eight minutes. The ears appear large on its small flattened head. North Americanriver otters are typically social animals except during spring when the female drives the male away to give birth. [1], During the 1970s, improvements in natural resource management techniques emerged, along with increased concerns about North American river otter population declines in North America.

The smallest otter species is the Asian small-clawed otter, and the largest species, with two tied for first, is the giant otter and the sea otter. Most mustelids, including otters, have 36 specialized teeth, including sharp canines and carnassials that inflict lethal bites to prey. Since inclusion under Convention on International Trade in Endangered Species of Wild Fauna and Flora, the U.S. They have a very high metabolism, so they need to eat frequently. We received responses from all 48 contiguous states and interviewed agency personnel in Alaska; not all responses were complete (Table S1). [36] A study conducted on captive otters revealed they preferred larger fish, ranging from 15 to 17 centimeters (5.9 to 6.7in), more than smaller fish, ranging from 8 to 10 centimeters (3.1 to 3.9in), and they had difficulty catching fish species less than 10 centimeters (3.9in) or larger than 17 centimeters (6.7in). Daniel Toole, Wildlife Biologist, Division of Wildlife and Freshwater Fisheries. Steele Creek Recreational Center, Satsuma, AL. [36], North American river otters may prefer to feed on crustaceans, especially crayfish (Cambarus, Pacifasticus, and others) and crabs[52] more than fish where they are locally and seasonally plentiful. CREATIVE. Our area estimates of river otter distribution in the contiguous United States during 2016 (e.g., 5,686,140 km2) were strikingly similar (i.e., only 2.3% greater) to what Melquist et al. [12], Molecular biological techniques have been used to determine when the river otter and the giant otter (Pteronura brasiliensis) of South America diverged. (Figure 1). Their aquatic habitats can be both marine and fresh water: streams, rivers, lakes, ponds and marshes. Consequently, many wildlife management agencies developed strategies to restore or enhance otter populations, including the use of reintroduction projects. [9] Other documented common names are American otter, Canada otter, Canadian otter, fish otter, land otter, nearctic river otter, and Prince of Wales otter. River otters generally live alone or in small social groups.

TheNorth Americanriver otter (Lutra canadensis) is a member of the weasel family. Otter play mostly consists of wrestling with conspecifics. For example, a study conducted in a central California marshland indicated crayfish formed nearly 100% of the river otter's diet at certain times of the year. We found that river otters have expanded their range significantly in the contiguous United States since the last assessment in 1998 (Melquist et al. The American river otter is a graceful and beautiful addition to many North Carolina rivers. They have also been known to eat aquatic plants and to prey on other small mammals, such as muskrats or rabbits. [34] Most aquatic invertebrates preyed upon by the otters are from the families Odonata (dragonfly nymphs), Plecoptera (stonefly nymphs), and Coleoptera (adult beetles). north american river otter. [30][32] They are less likely to be prey for the North American river otters since they are fast-swimming and can find good escape cover. Our survey indicated that <50% of the river otter reintroductions implemented in the United States were in areas where otters had been extirpated. The river otter was included as an Appendix II species under the Convention on International Trade in Endangered Species of Wild Fauna and Flora in 1977 as a result of concern that endangered otter species, such as Pteronura brasiliensis, could be misidentified as river otter because of a similar superficial appearance, which could lead to unintentional trade of endangered species; however, it is important to note that the river otter itself has never been considered a globally threatened or endangered species (Greenwalt 1977). after 100 years, "Final report of the North American river otter research project on the Upper Colorado River Basin in and adjacent to Rocky Mountain National Park, Colorado", "Asian Carp in the Diet of River Otters in Illinois", "Lontra canadensis (northern river otter)", COSEWIC assessment and status report on the Grizzly Bear, https://en.wikipedia.org/w/index.php?title=North_American_river_otter&oldid=1139111877, Fauna of the Sierra Nevada (United States), Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 13 February 2023, at 12:17. An adult river otter can weigh between 5.0and14kg (11.0and 31lb). [23], Although commonly called a "river otter", the North American river otter is found in a wide variety of aquatic habitats, both freshwater and coastal marine, including lakes, rivers, inland wetlands, coastal shorelines, marshes, and estuaries. We thank the many state natural resource agencies for their responses and cooperation. ), daces (Rhinichthys spp. The majority of these projects were implemented in the mid-1980s and were completed by the late 1990s; only two states (New York and Pennsylvania) were actively engaged in reintroductions during 1998 (Raesly 2001). The river otter is considerably larger, reaching several feet in length. Birds and birds' eggs, as well as small terrestrial mammals may also be eaten. The playful North American river otter is well adapted for semi-aquatic living. This dilemma prevents, and consequently inhibits, recolonization or growth of North American river otter populations. Fish are a favorite food, but they also eat amphibians, turtles, and crayfish. Current status of populations unknown. If there is no evidence of otters in a body of water it could mean that the body of water has been polluted or is unhealthy. Mink, Muskrat, Otter, and Striped Skunk. Twenty-one of the 23 states (91.3%) that implemented reintroductions reported that populations were increasing or had reached population goals, and 2 states (Minnesota and North Dakota) indicated that populations were stagnant or geographically restrained (Table 1). (1996) encouraged jurisdictions to standardize monitoring methodology. The female otters do not dig their own dens; instead, they rely on other animals, such as beavers, to provide suitable environments to raise their offspring. The tail makes up about a third of their total length. Even the otters at the zoo have chosen their own latrine sights. Although populations may continue to increase numerically, river otters may be approaching their potential maximum geographic distribution in the United States. Otters are what we call an indicator species. This means that if there is evidence of otters living in a body of water then that body of water is likely very healthy and clean. Although methodologies and sampling scales differed from the approach used in our assessment, comparisons of land areas occupied during each period provided a coarse-scale basis for estimates of population expansion or retraction during an 18-y period. Please note: The Journal of Fish and Wildlife Management is not responsible for the content or functionality of any supplemental material. beaver river otter. These harvest-dependent data can be synthesized in appropriate population models to yield a wealth of information on population status and trends (Roberts 2010). These hydrodynamic members of the weasel family are voracious predators. Uniting all Americans to ensure wildlife thrive in a rapidly changing world, Inspire a lifelong connection with wildlife and wild places through our children's publications, products, and activities, National Wildlife Federation is a 501(c)(3) non-profit organization. [53] A study conducted on North American river otters in a southwestern Arkansas swamp identified a correlation between crayfish consumption, fish consumption, and water levels. They live in riparian zones, often in the same areas as beavers. The Lower Alabama River begins at the Claiborne Lock and Dam and runs south 72.5 miles through Monroe, Clarke, and Baldwin counties where it joins the Tombigbee River. Adult body weights vary greatly, but normally range from 11 to 33 pounds. We categorized the frequencies of regulatory review within state agencies into the following: never, every 45 y, every 23 y, annually, and immediately as needed. [31][33], Mammals are rarely consumed by North American river otters, and are not a major dietary component. River otters are rambunctious, aquatic, streamlined mammals that spend much of their time in the water. The species is widely distributed throughout its range. They have small, round heads with small eyes and ears and prominent whiskers. Size Adult river otters weigh 10 to 33 pounds (4.5 to 15 kilograms) and are about 2.5 to 5 feet (76 to 152 centimeters) in length. October 29 - February 28. We reiterate Chilelli et al. The continued expansion of river otter populations where they are managed by regulated harvest is likely enhanced by the frequency of these regulatory reviews. [23][16], North American river otters characteristically approach within a few feet of a boat or a person on shore because they're near-sighted, a consequence of vision adapted for underwater sight. Are otters endangered in Alabama? Responses for population trends included increasing, stable, or decreasing (although we did not specify the timeframe). [54] However, when water levels are lower, crayfish will seek out shelter while fish become more highly concentrated and susceptible to predation. Only four statesNevada, Rhode Island, Utah, and Wyomingdid not report any monitoring efforts. We also thank the Association of Fish and Wildlife Agencies for logistical assistance. North American river otters are not scavengers; they avoid consuming carrion (dead animals). Houghton Mifflin Co., New York, NY. Estimated range of river otters Lontra canadensis in the United States during 2016 compared with 1998 (estimated from Melquist et al. Even in larger bodies of water, river otters may take disproportional advantage of any seasonal concentrations of fish when and where only very limited areas of suitable spawning, low-flow, or over-wintering habitat may exist. [50] Fish species frequently found in the diets of the North American river otters include: Catostomidae, which consists of suckers (Catostomus spp.) North American river otters have a transparent inner eyelid (called a nictitating membrane) to protect their eyes while swimming.[10][24][25]. [20] Large male North American river otters can exceed a weight of 15 kilograms (33lb). River otter track Scientific Name. They are born blind and remain in the den to nurse for the first month. Peterson Field Guide, Mammals. As such, careful consideration of any threatened, endangered, or fish species of special interest is warranted prior to reintroduction of otters to a watershed. The first River Otter that I have seen and I visit the area daily. An otters home range may be as small as five miles to as large as 40 miles. [39] Remains of the much larger North American beaver have been found in North American river otter scat in some regions, although most otter dietary studies in areas where otters and beaver live near each other do not show them to be regular predators of beavers (despite the claims of fur-trappers that otters frequently hunt beavers) and perhaps only young beaver kits may be attacked. 2003). The otter can close its ears and nostrils when diving. (c) Wikipedia, some rights reserved (CC BY-SA). Scientific studies have shown them to be sensitive to pollution. In the absence of harvest-dependent data, presenceabsence data (such as track surveys), can indicate population distribution and trajectories (Roberts et al. Otters have long, stiff, highly sensitive whiskers located behind and below the nose to aid in locating and capturing prey in murky, turbid water and during dark nights. [29] For instance, Catostomidae are the primary dietary component of North American river otters in Colorado's Upper Colorado River Basin. Also, North American river otters have large molars used for crushing hard objects, such as the shells of molluscs. However habitat destruction and water pollution still puts these animals at great risk, especially because they are so specialized. In some regions, though, their population is controlled to allow the trapping and harvesting of otters for their fur. [11], In a new classification, the species is called Lontra canadensis, where the genus Lontra includes all the New World river otters. Late seasonal breeding of river ot- ters in Yellowstone National Park. 2003). A river otter chews on a chunk of raw fish during feeding time at the Florida Aquarium in Tampa in 2021.. Low Conservation Concern. Although the distribution became reduced in some regions of southern Canada, the only province-wide extinction occurred on Prince Edward Island. More than one-third of U.S. fish and wildlife species are at risk of extinction in the coming decades. (c) Matt Muir, some rights reserved (CC BY-NC-SA). Nathan M. Roberts, Matthew J. Lovallo, Shawn M. Crimmins; River Otter Status, Management, and Distribution in the United States: Evidence of Large-Scale Population Increase and Range Expansion. Life on Land On. The species is also present throughout Alaska, including the Aleutian Islands, and the north slope of the Brooks Range. 2003) using ArcMap (ESRI 2011).
