  • The Marsh Wren (Cistothorus palustris) is a small, formally common, North American songbird inhabiting cattail marshes whose numbers have declined with the loss of suitable wetland habitat. Draining of marshes leads to its local extinction.  <br />
<br />
These birds forage actively in vegetation, sometimes flying up to catch insects in flight. They mainly eat insects, but may also consume spiders and snails.  The Marsh Wren sings all day and throughout the night producing a gurgling, rattling trill often used to declare ownership of its territory.<br />
<br />
The nest is an oval lump of woven wet grass, cattails, and rushes, which is lined with fine grass, plant down, and feathers.  It is attached to marsh vegetation and entered from the side. Industrious male Marsh Wrens build "dummy nests" in their nesting territories, occasionally up to twenty or more, although most are never used for raising young.  <br />
<br />
Normally four to six eggs are laid twice each year, although the number can range from three to ten.  The eggs are generally pale brown and heavily dotted with dark brown; although sometimes they may be all white. Only the female incubates the eggs which hatch after 13-16 days. The young leave the nest about 12-16 days after hatching.

  • The emu (Dromaius novaehollandiae) is the second-tallest living bird in the world exceeded only by the ostrich. Emus are endemic to Australia where it is the largest native bird and is found throughout most of mainland Australia.  <br />
<br />
Emus are soft-feathered, brown, flightless birds with long necks and legs, and can reach up to 1.9 meters (6.2 ft) in height. Emus range in length from 139 to 164 cm (55 to 65 in).  They are the fifth heaviest living bird in the world after the two species of ostrich and two larger species of cassowary.  Adult emus weigh between 18 and 60 kg (40 and 132 lb), with an average of 31.5 and 37 kg (69 and 82 lb) in males and females, respectively.<br />
<br />
Emus can travel great distances, and when necessary they can sprint at 50 km/h (31 mph) due to their highly specialized pelvic limb musculature.  They flap their wings when running, perhaps as a means of stabilizing themselves when moving fast.  When walking, the emu takes strides of about 100 cm (3.3 ft), but at full gallop, a stride can be as long as 275 cm (9 ft). Emus have good eyesight and hearing.<br />
<br />
Emus primarily eat plants and insects but can go for weeks without eating. They drink infrequently but ingest large amounts of water when they do.  Emus breed in May and June.  The male incubates the eggs and hardly eats or drinks during that time, losing a significant amount of weight. The eggs hatch after about eight weeks, and the young are nurtured by their fathers. Emus reach full size after about six months.  The emu plumage varies in color due to environmental factors.  Feathers of emus in more arid areas with red soils have a rufous tint while birds residing in damp conditions are generally darker in hue. The juvenile plumage develops at about three months with the head and neck being especially dark. The adult plumage has developed by about fifteen months.

  • The black-capped chickadee (Poecile atricapillus) is a small, nonmigratory, North American songbird that lives in deciduous and mixed forests. The chickadee is the state bird of Massachusetts, USA.  Its familiar call of chick-a-dee-dee-dee gave this bird its name.  The chickadee total body length is 12–15 cm (4.7–5.9 in), with a wingspan is 16–21 cm (6.3–8.3 in) and a body mass of 9–14 g (0.32–0.49 oz).   Sexes look alike, but males are slightly larger and longer than females.<br />
<br />
The chickadee has fascinating eating habits.  Insects (especially caterpillars) form a large part of their diet in summer. Seeds and berries become more important in winter.  Like many other species in the family Paridae, black-capped chickadees commonly cache their food, mostly seeds but sometimes insects also.  Items are stored singly in various sites such as bark, dead leaves, clusters of conifer needles, or knotholes. The chickadee can remember the location of caches up to 28 days.   Within the first 24 hours, the birds can even remember the relative quality of the stored items. <br />
<br />
The chichadee is also well known for its uncommon capability to lower its body temperature.  During cold winter nights, these birds can reduce their body temperature by as much as 10 to 12 °C (from their normal temperature of about 42 °C) to conserve energy.

  • A House Finch (Haemorhous mexicanus) perches in front of an azalea that has changed color in the fall.  These finches are 5-6 inches long with a 8-10 inch wingspan and a weight of 0.6-1.0 ounces.  Male coloration varies in intensity with the seasons and is derived from the berries and fruits in the bird's diet. Originally only a resident of Mexico and the southwestern United States, they were introduced to eastern North America in the 1940s. The birds were sold illegally in New York City as "Hollywood Finches".  To avoid prosecution under the Migratory Bird Treaty Act of 1918, vendors and owners released the birds. House Finches have become naturalized across the Eastern U.S., where now there are an estimated 267 million to 1.7 billion individuals in North America.

  • The Northern Cardinal (Cardinalis cardinalis) is a North American bird also known colloquially as redbird or common cardinal. It can be found from southern Canada, through the eastern United States and south to Mexico. It prefers woodlands, gardens, shrublands, and swamps.  The Northern Cardinal has a body length of 8-9 inches and a wingspan of 10-12 inches.  The male is a vibrant red, while the female is a dull red-brown shade. The Northern Cardinal is mainly granivorous, but also feeds on fruit or insects as shown here (note the wasp in the bird's beak).  The cardinal was once prized as a pet, but its sale as cage birds is now banned in the United States by the Migratory Bird Treaty Act of 1918.  This particular male Northern Cardinal is in the process of eating a wasp as it perches in a Red Maple (Acer rubrum) that is just coming into bloom.

  • A young Red-winged Blackbird (Agelaius phoeniceus) fledgling begs for food at the edge of Halycon Lake in Mount Auburn Cemetery. <br />
<br />
The red-winged blackbird is found throughout most of North and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica. It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the southern United States. <br />
<br />
The red-winged blackbird has been considered the most abundant living land bird in North America, with more than a million birds per flock and the total number of breeding pairs across North and Central America exceeding 250 million in peak years. <br />
<br />
The red-winged blackbird is sexually dimorphic with the male being all black with a red shoulder and yellow wing bar, while the female is a nondescript dark brown. Red-winged blackbirds are polygynous, with territorial males defending up to 10 females. Seeds and insects make up the bulk of the red-winged blackbird's diet.<br />
<br />
Male red-wing blackbirds grow to 22–24 cm (8.7–9.4 in) long and weigh 64 g (2.3 oz).  Females are smaller.  They build their nests in cattails, rushes, grasses, sedge, or in alder or willow bushes. The nest is constructed entirely by the female over the course of three to six days. A clutch consists of three or four, rarely five, eggs. Eggs are oval, smooth and slightly glossy, and measure 24.8 mm × 17.55 mm (0.976 in × 0.691 in). They are incubated by the female alone, and hatch in 11 to 12 days both blind and naked.  However, they are ready to leave the nest 11 to 14 days after hatching.

  • Multiple flocks of migrating Canada Geese (Branta canadensis) are silhouetted against the evening sky as the sun sets over Blackwater National Wildlife Refuge on the Eastern shore of Maryland, Halloween night, October 31, 1990.  Blackwater National Wildlife Refuge, encompassing over 27,000 acres of wetlands, is a major stop on the Atlantic Flyway for many types of waterfowl and other birds.  The refuge, established in 1933 as a waterfowl sanctuary, has been designated of “International Importance" by the Ramsar Convention as it supports over 250 bird species, 35 species of reptiles and amphibians, 165 species of threatened and endangered plants, and numerous mammals.  During winter migration, Blackwater Refuge is home to approximately 35,000 geese and 15,000 ducks. Fed by the Blackwater River and the Little Blackwater River, it consists of numerous freshwater impoundments, brackish tidal wetlands, open fields, and mixed evergreen and deciduous forests. The Blackwater name refers to the tea-colored waters darkened by tannins leached from the marsh peat soil through which they drain.

  • A young Red-winged Blackbird (Agelaius phoeniceus) perches amongst common cattails (Typha latifolia) at Great Meadows National Wildlife Refuge. <br />
<br />
The red-winged blackbird is found throughout most of North and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica. It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the southern United States. <br />
<br />
The red-winged blackbird has been considered the most abundant living land bird in North America, with more than a million birds per flock and the total number of breeding pairs across North and Central America exceeding 250 million in peak years. <br />
<br />
The red-winged blackbird is sexually dimorphic with the male being all black with a red shoulder and yellow wing bar, while the female is a nondescript dark brown. Red-winged blackbirds are polygynous, with territorial males defending up to 10 females. Seeds and insects make up the bulk of the red-winged blackbird's diet.<br />
<br />
Male red-wing blackbirds are 22–24 cm (8.7–9.4 in) long and weigh 64 g (2.3 oz).  Females are smaller.  They build their nests in cattails, rushes, grasses, sedge, or in alder or willow bushes. The nest is constructed entirely by the female over the course of three to six days. A clutch consists of three or four, rarely five, eggs. Eggs are oval, smooth and slightly glossy, and measure 24.8 mm × 17.55 mm (0.976 in × 0.691 in). They are incubated by the female alone, and hatch in 11 to 12 days both blind and naked.  However, they are ready to leave the nest 11 to 14 days after hatching.

  • The Marsh Wren (Cistothorus palustris) is a small, formally common, North American songbird inhabiting cattail marshes whose numbers have declined with the loss of suitable wetland habitat. Draining of marshes leads to its local extinction.  <br />
<br />
These birds forage actively in vegetation, sometimes flying up to catch insects in flight. They mainly eat insects, but may also consume spiders and snails.  The Marsh Wren sings all day and throughout the night producing a gurgling, rattling trill often used to declare ownership of its territory.<br />
<br />
The nest is an oval lump of woven wet grass, cattails, and rushes, which is lined with fine grass, plant down, and feathers.  It is attached to marsh vegetation and entered from the side. Industrious male Marsh Wrens build "dummy nests" in their nesting territories, occasionally up to twenty or more, although most are never used for raising young.  <br />
<br />
Normally four to six eggs are laid twice each year, although the number can range from three to ten.  The eggs are generally pale brown and heavily dotted with dark brown; although sometimes they may be all white. Only the female incubates the eggs which hatch after 13-16 days. The young leave the nest about 12-16 days after hatching.

  • This Red-tailed Hawk was stalking insects and small rodents in the grass at Mount Auburn Cemetery in Cambridge, Massachusetts.  <br />
<br />
The Red-tailed Hawk (Buteo jamaicensis), also sometimes known as a "chicken hawk", is one of the most common buteos in North America.  These hawks most commonly prey on small mammals such as rodents, but they will also consume birds, fish, reptiles, and amphibians.  Usually, they will eaither swoop down from an elevated location or attack in midair.  <br />
<br />
These hawks breed throughout most of North America, from western Alaska and northern Canada to as far south as Panama and the West Indies.  There are fourteen recognized subspecies, which vary in appearance and range. The Red-tail typically has a wingspan of 43 to 57 inches, being 18 to 26 inches in length and weighing 1.5 to 3.5 pounds, thus making it one of the largest members of the genus Buteo in North America.

  • A Great Blue Heron (Ardea herodias) stalks his prey along a ponds edge at Mount Auburn Cemetery in Cambridge, Massachusetts.  <br />
<br />
The Great Blue Heron is common near the shores of open water and in wetlands throughput most of North and Central America, as well as the Caribbean and the Galápagos Islands. It is the largest North American heron and the third largest heron in the world.  Great blue herons are 115–138 cm (45–54 in) tall with a wingspan of 167–201 cm (66–79 in) and weigh about 2.23 kg (4.9 lb) in New England where this individual was photographed.  These herons have long legs and cover approximately 22 cm (8.7 in) with each stride.  <br />
<br />
Herons locate their food by sight and usually swallow it whole. Typically, the great blue heron feeds in shallow waters, usually less than 50 cm (20 in) deep, by wading slowly and quickly spearing prey with its long, sharp bill. The primary food for the great blue heron is small fish, although they have been observed to feed on shrimp, crabs, aquatic insects, rodents, and small mammals, amphibians, reptiles, and birds.

  • The Southern Cassowary (Casuarius casuarius) is found in the tropical rainforests of Indonesia, New Guinea and northeastern Australia, preferring elevations below 1,100 m (3,600 ft) in Australia and below 500 m (1,600 ft) in New Guinea.  Also known as the Double-wattled Cassowary, Australian Cassowary or Two-wattled Cassowary, it is a large flightless black bird related to the emu, ostrich, rhea and its closest relative, the Kiwi, from which it diverged approximately 40 million years ago. <br />
<br />
The Southern Cassowary is the largest member of the cassowary family and is the second heaviest bird on earth, attaining a maximum estimated weight of 85 kg (187 lb) and height of 190 cm (6 ft 3 in). It is currently the largest living Asian and Australian bird.  <br />
<br />
Females as shown here are larger and more brightly colored than the males. A horn-like brown casque, measuring up to 16.9 cm (6.7 in) high, sits atop the head. The bill can be up to 19 cm (7.5 in) long. The three-toed feet are powerful and equipped with a lethal dagger-like claw up to 12 cm (4.7 in) on the inner toe. The blade-like claws are capable of killing humans and dogs if the bird is provoked. <br />
<br />
The Southern Cassowary forages on the forest floor for fallen fruit and can digest fruits toxic to other animals. It also eats fungi, insects and small vertebrates. <br />
<br />
The Southern Cassowary is a solitary bird, which pairs only in breeding season, in late winter or spring. Cassowaries make a booming call during mating season and hissing and rumbling sounds otherwise. The male builds a nest on the ground made of plant material 5-10 cm (2–4 in) thick and up to 100 cm (39 in) wide. The male incubates the eggs and raises the chicks alone. A clutch of three or four eggs are laid measuring 138 by 95 mm (5.4 in × 3.7 in). They have a granulated surface and are initially bright pea-green in color although they fade with age.

  • The Red-tailed Hawk (Buteo jamaicensis), also sometimes known as a "chicken hawk", is one of the most common buteos in North America.  These hawks breed throughout most of North America, from western Alaska and northern Canada to as far south as Panama and the West Indies.  There are fourteen recognized subspecies, which vary in appearance and range. The Red-tail typically has a wingspan of 43 to 57 inches, being 18 to 26 inches in length and weighing 1.5 to 3.5 pounds, thus making it one of the largest members of the genus Buteo in North America.

  • The tufted titmouse (Baeolophus bicolor) is a small, common songbird found throughout the east coast of the United States, to southern Ontario, Canada and westward to the plains of central Texas, Oklahoma, Nebraska, Kansas, and Iowa.  They are 5.9–6.7 inches long, weigh 0.6–0.9 ounces and have a lifespan of 2–13 years.  The highest population densities of tufted titmice occur along the Ohio, Cumberland, Arkansas, and Mississippi rivers where they prefer deciduous and mixed-deciduous forests, especially those with a dense canopy or tall vegetation. Tufted titmice feed on insects and seeds.

  • An American Alligator (Alligator mississippiensis) remains so motionless among the arrowhead plants (Sagittaria sp.) while hunting in a Florida marsh that a fly has landed and is walking across the Alligator’s nose. The American Alligator is the largest reptile in North America and is endemic to the southeastern United States ranging from Texas to North Carolina.  Adults can be up to 16 feet long (5 m) and can weigh 1,320 pounds (600 kg).  They will prey on anything that comes in or near the water including documented successful attacks on fish, turtles, crabs, birds, muskrats, racoons, dogs, cats, wild boars, bobcats, deer, calves and humans.  They will also eat fruit.  Adult alligators also spend considerable time hunting on land, up to 170 feet (50 m) from water, ambushing terrestrial animals on trail-sides and road shoulders. Such terrestrial hunting generally occurs on warm nights.  The alligator is capable of biting though a turtle's shell or a moderately sized mammal bone.  American alligators have been documented to use lures to hunt birds.  By balancing sticks and branches on their heads, American alligators are able to lure, catch and consume birds looking for suitable nesting material. During the breeding season, alligators bellow to declare territory and locate suitable mates, with males using infrasound to attract females. From 20 – 50 eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. Those eggs which are hatched at a temperature of 93 °F (34 °C) or more become males, while those at experiencing temperatures of 86 °F  (30 °C) or lower become female. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.  Young alligators grow 3 - 8 inches (7.6 - 20.3 cm) a year and reach adulthood at 6 ft (1.8 m).

  • Under a moonless night sky in Death Valley California, headlights from a passing car light the barren landscape at Zambriske Point making it seem as though one is standing on another planet looking out into the universe.  The upper left star cluster is the Pleiades (also known as the Seven Sisters or Messier object 45) which is a 100 million year old formation approximately 130 parsecs (424 light-years) from earth.<br />
<br />
Zabriskie Point is part of the Amargosa Range located on the eastern side of Death Valley.  The area is noted for its erosional landscape, composed of sediments from Furnace Creek Lake, which dried up 5 million years ago—long before Death Valley came into existence.  This ancient lake began forming approximately nine million years ago. During the several million years of the lake's existence, sediments composed of saline muds, mountain gravels, and ashfalls from the then-active Black Mountain volcanic field collected at the bottom of the lake.<br />
<br />
Camels, mastodons, horses, carnivores, and birds left tracks in the lakeshore muds, along with fossilized grass and reeds. Borates were concentrated in the lakebeds from hot spring waters and decomposition of rhyolite in the nearby volcanic fields. Indeed, the location is named after Christian Brevoort Zabriskie, vice-president and general manager of the Pacific Coast Borax Company in the early 20th century. The company's twenty-mule teams were used to transport borax from its mining operations in Death Valley.

  • An American mink defiantly protects its recent catch of a meadow vole alongside the marsh at Great Meadows National Wildlife Refuge.<br />
<br />
The American mink (Neovison vison) is native to North America, although its range has spread to many parts of Europe and South America. Since the extinction of the sea mink, the American mink is the only living member of the genus Neovison. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. It kills vertebrate prey by biting the back of the head or neck as seen in this photograph.  The meadow vole (Microtus pennsylvanicus) captured here, is one of the American mink’s primary food sources throughout its range including Canada, Alaska, and the northern United States.<br />
<br />
The American mink has a long body which allows the species to enter the burrows of prey. Its streamlined shape helps it to reduce water resistance when swimming and the thick underfur and oily guard hairs render its coat water-resistant.  In warm water (24 °C or 75 °F), the American mink can swim for three hours without stopping.  However, in cold water it can die within 27 minutes. It generally dives to depths of 12 in (30 cm) for 10 seconds, though depths of 3 m lasting 60 seconds have been recorded. It typically catches fish after five- to 20-second chases.  American mink molt twice a year, in spring and autumn.  The fur does not turn white in winter.<br />
<br />
Males measure 13–18 in (34–45 cm) in body length, while females measure 12–15 in (31–37.5 cm). The tail measures 6–10 inches (15.6–24.7 cm) in males and 6–8 in (14.8–21.5 cm) in females. In winter, males weigh 1–3 lb (500–1,580 g) and females 1–2 lb (400–780 g).  Maximum weight is achieved in autumn.<br />
<br />
The summer fur is generally shorter, sparser and duller than the winter fur.[11] The thick underfur and oily guard hairs render the pelage water-resistant, with the length of the guard hairs being intermediate between those of otters and polecats, thus ind

  • An American Bullfrog (Rana catesbeiana) waits motionless in a small pond completely covered in Duckweed (Lemnaceae) in hopes of catching a small fly (Drosophilidae) walking along the edge of its mouth.  <br />
<br />
The bullfrog is native to eastern North America with a natural range from the Atlantic Coast to as far west as Oklahoma and Kansas.  However, it has been introduced elsewhere where it is considered an invasive species, including Arizona, Utah, Colorado, Nebraska, Nevada, California, Oregon, Washington, Hawaii, Mexico, Canada, Cuba, Jamaica, Italy, Netherlands, France, Argentina, Brazil, Uruguay, Venezuela, Colombia, China, South Korea and Japan.  In some areas, the bullfrog is used as a food source.  <br />
<br />
Bullfrogs are voracious, ambush predators that eat any small animal they can stuff down their throats. Bullfrog stomachs have been found to contain rodents, reptiles, amphibians, crayfish, birds, bats, fish, tadpoles, snails and their usual food – insects.  Bullfrogs are able to jump a distance 10x their body length.  The female lays up to 20,000 eggs at a time that form a thin, floating sheet which may cover an area of 0.5 -1 m2 (5.4 - 10.8 sq ft). The embryos hatch in 3 - 5 days. Time to metamorphize into an adult frog ranges from a few months in the southern part of their range to 3 years in the north where the colder water slows development.  Maximum lifespan in the wild is 8 - 10 years, but one bullfrog lived for almost 16 years in captivity.<br />
<br />
Duckweed (Lemnoideae) are small flowering aquatic plants which float on or just beneath the surface of still or slow-moving bodies of fresh water. These plants lack obvious stems or leaves, and depending on the species, each plant may have no root or one or more simple rootlets.  Reproduction is mostly by asexual budding, however, occasionally three tiny flowers are produced for sexual reproduction.  The flower of the duckweed measures a mere 0.3 mm (1/100th of an inch) long.<br />

  • A sand lance (Ammodytes hexapterus) hides amongst brown Rockweed (Ascophyllum nodosum) and green Sea Lettuce (Ulva) in 25 feet of water off Folly Cove in Rockport, Massachusetts. Although also commonly known as "sand eels", the sand lance is not related to true eels. The family and genus name (Ammodytes) means "sand burrower", a reference to the sand lance's habit of burrowing into sand to avoid tidal currents.<br />
<br />
Sand lances are most common in the North Pacific and North Atlantic, but are found in oceans throughout the world. These fish do not have pelvic fins and do not develop swim bladders, being bottom-dwelling as adults. The larval form of the Sand Lance may be the most abundant of all fish larvae in areas such as the northwest Atlantic, serving as a major food for cod, salmon, whales and diving birds such as puffins, auks, terns, and cormorants. Sand lances can control the movement of each eye independently.

The embryos hatch in 3 - 5 days. Time to metamorphize into an adult frog ranges from a few months in the southern part of their range to 3 years in the north where the colder water slows development.  Maximum lifespan in the wild is 8 - 10 years, but one bullfrog lived for almost 16 years in captivity.<br />

Duckweed (Lemnoideae) are small flowering aquatic plants which float on or just beneath the surface of still or slow-moving bodies of fresh water. These plants lack obvious stems or leaves, and depending on the species, each plant may have no root or one or more simple rootlets.  Reproduction is mostly by asexual budding, however, occasionally three tiny flowers are produced for sexual reproduction.  The flower of the duckweed measures a mere 0.3 mm (1/100th of an inch) long.

  • This American Bullfrog (Rana catesbeiana) is hiding in a small pond completely covered in Duckweed (Lemnaceae).  The bullfrog is native to eastern North America with a natural range from the Atlantic Coast to as far west as Oklahoma and Kansas.  However, it has been introduced elsewhere where it is considered an invasive species, including Arizona, Utah, Colorado, Nebraska, Nevada, California, Oregon, Washington, Hawaii, Mexico, Canada, Cuba, Jamaica, Italy, Netherlands, France, Argentina, Brazil, Uruguay, Venezuela, Colombia, China, South Korea and Japan.  In some areas, the bullfrog is used as a food source.  <br />

  • An American Robin (Turdus migratorius) finishes a worm for breakfast while perched on a sign in Mount Auburn Cemetery, Cambridge, Massachusetts.  The American Robin is a migratory songbird of the thrush family, widely distributed throughout North America.  They winter from southern Canada to central Mexico and along the Pacific Coast. It is the state bird of Connecticut, Michigan, and Wisconsin. The American Robin is the second most abundant land bird in North America (after the Red-winged Blackbird). They are generally 23 - 28 cm (9.1 - 11.0 in) long with a wingspan ranging from 31 - 41 cm (12 - 16 in) and averages about 77 g (2.7 oz) in weight.  The American Robin has an extensive range, estimated at 16 million km2 (6,2 million sq mi), and a large population of about 320 million individuals. At one point, the bird was killed for its meat, but it is now protected throughout its range in the United States.  They lay 3 - 5 light blue eggs which are incubated by the female alone. The eggs hatch after 14 days, and the chicks leave the nest 2 weeks later.  Only 25% of chicks survive the first year.  The longest known lifespan in the wild of an American Robin is 14 years, but the average lifespan is about 2 years.

  • This eastern chipmunk (Tamias striatus) built its home below a sewer grate in Mount Auburn Cemetery, Cambridge, Massachusetts.  They generally construct underground nests with extensive tunnel systems, and several entrances.  To hide the construction of its burrow, the eastern chipmunk carries soil away from its hole in its cheek pouches.  <br />
<br />
The eastern chipmunk is the sole living member of the chipmunk subgenus Tamias, and is found only in eastern North America.  The name "chipmunk" is derived from the Algonquian language meaning “one who descends trees headlong.”  <br />
<br />
The eastern chipmunk reaches 30 cm (12 in) in length including the tail, with a weight of 66–150 g (2.3–5.3 oz).  Interestingly, it has two fewer teeth than other chipmunks and four toes each on the front legs, but five toes on each of the hind legs.  They are mainly active during the day, consuming bulbs, seeds, fruits, nuts, green plants, mushrooms, insects, worms, and bird eggs.  <br />
<br />
The eastern chipmunk leads a solitary life, except during mating season. Females usually produce one or two litters of three to five young, usually from February to April and/or June to August. On average, eastern chipmunks live three or more years in the wild, although in captivity they may live up to eight years.
