Friday 28 January 2011 Slow Loris - Soft with a Poisonous Bite

Slow lorisThe Slow Loris (Nycticebus coucang), is a critically endangered species in the Loris family. It is one of the Strepsirhini primates, and is found in parts of Southeast Asia. Its fur coat is thick and soft. The eyes are large, round and inquisitive. This friendly looking animal has a soft, welcoming appearance, but it actually dangerous due to its poisonous bite.

This species is quite small, weighing in at between 21 and 24 oz. (599 - 685 g). Its length is also small, measuring between 10 to 15 inches (27 - 38 cm). They are covered completely in fur, including their tail, which is short enough to be hidden in the coat. This extremely thick fur is a light brown color, with a darker stripe that extends from the top of the head to the tip of the short tail. Its face is highly expressive. A nocturnal animal, the eyes of the Slow Loris are large and round, lending it a look of inquisitiveness. The eyes and face are further highlighted by dark brown rings that surround each eye and a thick, white stripe that runs between the eyes.

This genus of Loris can be found in tropical rainforests. They are attracted to the thick foliage, sometimes found in bamboo groves, that will also be home to much of their preferred diet. Indonesia, the Malay Peninsula and Thailand are all home to this particular species. However, their numbers are diminished and they can be difficult to find. Being superb climbers, they make their homes in tall trees. During the day they curl into tight balls, tucking their heads between their thighs. When disturbed or startled, they will make a buzzing or hissing noise. The name of this species becomes clear when observing movements, as it moves very slowly. The steps are deliberate, and the Loris will typically maintain three points of contact with the tree branch as it moves. However, the Slow Loris is not limited to these types of movements. When the Loris is catching prey or escaping predators, it can move very quickly.

Tiny, extremely sharp teeth allow the Slow Loris to enjoy its diet of lizards, bird eggs, insects, tree sap, and nectar. In addition to these smaller meals, the Loris will also capture and dine on small birds and other small mammals. This species has glands on its inner elbow that secrete a poisonous toxin. This toxin is used as both a weapon and a form of protection. The toxin can be sucked into the Slow Loris' mouth, giving it the poisonous bite. It can also be smeared over the bodies of its offspring, protecting them from predators.

Predators of the Slow Loris include pythons and hawk eagles. Fortunately the Slow Loris can effectively protect itself from most predators by using its own toxin as a shield. By curling into a tight ball, the Loris can actually excrete the toxin onto its back, effectively protecting itself from most predators. It also has the ability to simply release its hold on the tree branch and fall to safety. However, the Slow Loris has not been able to find a protection from its greatest threat: mankind. Expanding urban areas are destroying their habitats, and their appearance makes them highly attractive additions to the exotic pet market. Their soft fur and inquisitive appearance make them highly desirable pets for some people, even though they are wild animals and are never recommended as such. Exotic pet traffickers will remove or cut their sharp teeth, protecting potential owners from their bite. Once this is done, the Slow Loris can never be returned to the wild.

Wednesday 26 January 2011 European Water Vole - Star of Stage and Screen

Water voleThe European water vole (Arvicola terrestris) was considered a separate species from Arivicola amphibius until 1857. At that time the two were found to be the same species and is generally referred to as Arivicola amphibius. It is found all over Great Britain, north and central Europe and in parts of Russia digging nests in the banks of streams, slow moving rivers and other waterways. Their nests have many rooms, and some are used for food storage for the long winter.

The cute aspect and busy nature of the water vole has captured the imagination of authors and their public. Ratty, the main character in The Wind in the Willows by Kenneth Grahame was actually a water vole. Also, in Stella Gibbons’ comic novel and film Cold Comfort Farm one of the characters talks to water voles throughout the story.

They prefer to live in thick riparian vegetation which protects them from predators when they are above ground. They don’t like trampled grass or trees where predators can hide. The American mink was the main predator and almost hunted the voles to extinction (see also this article). They are protected now in the UK and are on the International Union for Conservation of Nature (IUCN) list as Least Concern.

Water voles are commonly mistaken for rats and called water rats in some places even though they have fur on their ears, paws and tails and have short noses. They have chubby faces and bodies and are excellent swimmers and divers. They grow to 5.5-8.7 inches (140-220 millimeters) long plus a tail of 2.2-2.8 inches (55-70 millimeters). Adult water voles weigh from 5.6-12.3 ounces (160-350 grams). Babies must grow to 4.9-6.0 ounces (140-170 grams) to survive the first winter.

Pregnancy is 21 days and a litter may contain up to eight babies. Each one weighs about 0.4 ounces (10 grams). They open their eyes three days after birth and can expect to live two years. Most water voles do not live through a second winter.

They eat grass and plants that grow near water and sometimes bulbs, twigs, buds, roots and fruits. When there is no apparent reason, because there is enough food available, they can destroy the grass of a whole field like a plague. They will eat voraciously leaving it bare. They have even been known to eat frogs’ legs in Wiltshire, England. They do this possibly to make up for a lack of protein in their diet.

Monday 24 January 2011 The Annually Fruitful Gray Brocket

Gray brocketThe Gray brocket (Mazama gouazoupira) deer has a grayish-brown coat, and the underside of its tail is white. When fully grown, gray brockets average a weight of 17 kg, or 37.4 lbs. They measure approximately 850 to 1050 mm, or 41.34 to 33.46 inches. Male gray brocket deer have antlers measuring from 70 to 100 mm. The gray brocket makes its home in Bolivia, Argentina, Colombia, Brazil, French Guiana, Ecuador, Peru, Guyana, Trinidad and Tobago, Suriname, Venezuela and Uruguay and prefer open areas, such as the thorn scrub in Venezuela and may be found in arid regions, swamplands, savannas, or on the borders of transitional forests.

The gray brocket deer reproduces year round. Does have been found pregnant and lactating simultaneously, and spotted fawns may be found all through the year. Gestation averages eight months. Generally only one offspring is born at a time, twins occur rarely.

The average lifespan of gray brocket deer is 13 years in the wild. Rarely seen in groups of three, they are solitary animals, preferring cover during the day and to feed in the open only at night. Female home ranges overlap, but male home ranges are exclusive.

Gray brocket deer communicate through scent-marking, including defecation, urination, thrashing, and forehead rubbing. Females and juveniles have been known to mark more often inside their home range than males, who usually mark outside their range. Other communication methods include posture, visual signals, physical contact, and some vocalizations.

Mostly frugivorous, gray brocket deer prefer fleshy fruits from bush-like trees during the wet season. They feed on tough fruit from the Casesalpinia paraguarensis and the Zyzyphus oblongifoia trees during the dry season. This fruit is dry and tough. In regions like the Chaco, water is more scarce during the dry season, so the deer eat more bromeliad and cacti fruits, in addition to succulent roots and leaves, to fulfill their need for water. They also eat twigs, buds, flowers, bark, and tree or shrub leaves. Because of the type of food they eat, they disperse seeds from many plants. Due to predators’ reliance on these deer for food, they may affect predator populations.

Predators of gray brocket deer include jaguars, ocelots, domestic dogs, mountain lions, humans, and large raptors. They are listed on the IUCN Red List of Threatened Species as Data Deficient, which means there is inadequate information for directly assessing its risk of extinction.

Friday 21 January 2011 Siberian Weasel - The Ubiquitous Asian Mustelid

Siberian weaselThe Siberian weasel (Mustela sibirica), which is also referred to as the Yellow or Himalayan Weasel, is a relatively widespread animal indigenous to Asia. Due to the wide distribution and large population of the animal, they are classified as least concern for extinction.

The Siberian weasel has a long body and short legs but is huskier than their stoat relatives. The head of the animal is elongated as well as narrow with the ears being broad yet short. The tail is quite long and consists of approximately half of the creature’s length in total. The adult male weasel is about 28 to 32 centimeters or 11 to 12.6 inches in length with the females ranging from 25 to 30.5 centimeters or 9.8 to 12 inches. The weight of the male ranges from 650 to 820 grams or 23 to 29 ounces with the females being significantly lighter, ranging from 360 to 430 grams or 13 to 15 ounces.

The winter coat of the animal is soft yet dense with the underfur being quite loose against the body. The weasel is completely monotone in coloration, typically being straw-red although the skin may have a pale peach or orange tone.

The Siberian weasel has an long rutting period that depends largely upon the location in which the animal lives. The rut typically begins during the early part of February and ends in late March in the Siberian regions. They mate for approximately 35 minutes and do so repeatedly. The gestation period of the animal can last anywhere from 38 to 41 days, with the litter averaging around 6 kits.

Unlike most animals, the weasel is not particular about where it makes it home. They have been found in rotted out stumps, tree roots, and may also become squatters in the abandoned homes of other animals. Along with their permanent home, the Siberian weasel has about five additional shelters which serve as more temporary housing.

The weasel preys predominantly on rodents who are smaller than they such as water voles, voles, and mice as well as chipmunks, red squirrels, and muskrats. The predators of the creature primarily consist of owls and other birds of prey.

These weasels can be found in many parts of Asia including Laos, northern Myanmar, Pakistan, North Korea, India, Bhutan, Nepal, Russia (particularly in Siberia and the northern parts of the country), the northern part of Thailand, and Taiwan.

Thursday 20 January 2011 Geoffroy's Bat - Winning the Survival Struggle?

Geoffroys BatThe Geoffroy%u2019s bat (Myotis emarginatus) is also known as Geoffroy’s Myotis. Geoffroy’s bat can be found in central and southern Europe, northwestern Africa, Caucasus and Levantine regions, and the eastern Mediterranean. Although plentiful in some parts of France, it is much rarer in the rest of Europe and appears on their species needing further research and protection. They mature in about a year and a half and start the cycle of having a pup of their own annually. An adult weighs about .011 kg and will live 23 years. Geoffrey’s bats live in large groups known as colonies or clouds. These can be as large as 1200 bats.

Endangered

Geoffroy’s bat has been listed as “Vulnerable” since 1996 and has a high risk of extinction according to the IUCN Red List of Threatened Species. The last assessment was in 2008 when it was considered of "least concern". In some areas populations experienced a significant decline between the 1960s to the 1990s.

More recent indications are that populations of Geoffroy’s Bat are growing in central Europe and at least close to stable in most other areas. It has even moved into new areas.

Locations and Habitat of Geoffroy’s Bat

This bat can make its home across a wide range, as it is adaptable and not restricted to a special habitat. Its biggest restriction is its specialized diet. It needs grassland where it can forage through scrub for spiders and flies. It will live anywhere from sea level to about 1800 m.

This species travels very little and is not known for migration. However there are some places it is seen only in the summertime. It tends to live underground, especially in the winter. During summer months it can also be found settled in the attics of buildings. Some African colonies reside in caves.

Geoffroy’s Bat’s Biggest Adversaries

Man is the Geoffroy’s Bat’s biggest threat.

Since Geoffroy’s Bat is found largely over agricultural landscapes, changes in agricultural activities can influence populations. Any large scale disturbance of the earth or removal of buildings can take away their homes. The African caves are being threatened by vandalism and fires. African traditional medical procedures also require the bat, and many are collected each year.

Wednesday 19 January 2011 Bicolored Shrew - An Animal a Dentist Would Love

Bicolored shrewThe bicolored shrew (Crocidura leucodon), also known as the white-toothed shrew, is a small mammal known by its distinctive coloring. The bicolored shrew is a medium to dark brown on its back and white or light gray on its underbelly. This difference in color is immediately obvious, as the variation is clearly defined.

However, those that look even further will notice that the bicolored shrew is equipped with bright, white teeth. Its teeth are such a stark white, not due to the shrew’s diet, but because its teeth lack natural pigmentation. These teeth are also sharp and tightly crowded together, even more so than other white toothed shrew species.

Besides their ability to impress any dentist, the bicolored shrew’s teeth are also put to good use. These animals are aggressive carnivores that will feast on any small animal they can find. These shrews prefer to hunt small mammals, frogs, and lizards, but will eat insects if prey is scarce. The bicolored shrew also has a peculiar way of consuming their prey. Instead of going for the large, meaty portions of the body, bicolored shrews always eats their prey’s brain first. They will then eat the rest of their prey, leaving only unwanted limbs, skin, and tails.

While the bicolored shrew may sound frightening, it is actually fairly small. An adult shrew weighs 0.024 pounds, or 0.011 kilograms, and grows to about 3.82 to 5.24 inches, or 97 to 133 millimeters, in length.

Additionally, this shrew is native to Central Europe and prefers dry, temperate habitats. Bicolored shrews find their homes in woodlands and grasslands, where they are offered many places to hide. Shrews prefer to burrow and build tunnels under rock piles or thick brush, in order to disguise and protect their homes. Bicolored shrews will also make themselves at home in people’s gardens, farmlands, and farm buildings, frequently to the dismay of the inhabitants.

The bicolored shrew is plentiful in Central Europe and is currently not at risk for extinction. However, this animals does find itself hunted by a number of different animals, including snakes, owls, and other carnivorous mammals. Fortunately, those that want the opportunity to see the bicolored shrew, will not find it difficult, although they may want to keep a safe distance from this aggressive little mammal.

Tuesday 18 January 2011 Red-chested mustached tamarin - A patient hunter

Red-chested mustached tamarinThe Red-chested mustached tamarin (Saguinus labiatus) is a stealthy hunter that hides in bushes and patiently waits for frogs, snails, lizards, spiders and other insects to be within reach before it pounces and makes a meal of them. Its diet also consists of flowers, nectar and fruits.

The Red-chested mustached tamarin resides in the upper layer of the rainforests and swamps of Brazil and Peru. They often mingle and form groups with the Saddleback Tamarin, which is smaller in size. The Red-chested mustached tamarin weighs between 491 and 529 grams or 1.08 and 1.17 pounds. Its head and body ranges in length from 23 to 30 cm or 9.1 to 11 inches, and its tail length is 34 to 41 cm or 13 to 16 inches.

The most distinguishable features of the Red-chested mustached tamarin are also the reasons for its name. It has bright reddish hair on its stomach, along with white hair that surrounds its lips and nose, giving it a mustached look.

This tamarin is known for its long calls, which consist of individual syllables. It has been found that the acoustic structure of the call is different between each group. Studies on males and females of different groups have shown that the females can distinguish the calls of the males from their own population and responds to them differently than calls from an unfamiliar population.

The Red-chested mustached tamarin is not endangered and is listed as Least Concern. This is most likely due to the fact that much of the population lives in a remote area of the Brazilian Amazon and is not hunted in any great number; however, they are sometimes captured and kept as pets. They have no known major threats and are very adept at avoiding predators by carefully choosing their sleeping spots, usually in tree branches 12-18 meters (39 to 59 feet) above ground.

A female will be pregnant for almost 5 months and will usually give birth to twins. The babies are raised by the entire group, which is between 4 and 15 individuals, and are not weaned until they are almost 8 months old. The Red-chested mustached tamarin has a long lifespan, approximately 21 years.

Monday 17 January 2011 Chilean guemal - Chile's endangered national symbol

Chilean guemalThe Chilean guemal (Hippocamelus bisulcus) is a highly endangered species of deer found in the high, frigid mountains of Chile and Argentina. They are also sometimes called the Chilean huemul, South Andean huemul, Patagonia huemul and taruca. With compact bodies and short legs, this species is well-adapted to surviving in the rugged and difficult terrains of the Andes mountains. They have long been a symbol of Chile and are depicted on its national coat-of-arms.

As with most species of deer, the Chilean guemal is distinguished with a short tail and thick coat of hair. Their hide is brown to grayish-brown across the back and sides, tapering to white on the undersides and along the throat. They are known for their very thick, curly hairs which help protect them in weather that is often well below zero. Their average weight and height ranges from 70 kg. (154 lbs.) and 80 cm. (31 in.) for does to 90 kg. (198 lbs.) and 90 cm. (35 in.) for bucks. Only the bucks have antlers, which they shed each year at the end of winter. Bucks also have a distinctive black face mask which is shaped like an elongated heart. All fawns are born without spots.

Although they were once very common in the mountainous regions of lower, southwestern South America, the populations of Chilean guemal are now found only in Chile and very limited parts of Argentina. They prefer to live in herds consisting of both males and females. Most of their time during the summer months is spent in very high and rugged mountain cliffs while in winter they prefer the lower, forested valleys. Their diets consist mainly of plants and shrubs such as lichens, grasses and leaves.

The status of the Chilean guemal is now ranked as extremely endangered. Although the cougar is its only major natural predator, many other factors have caused a rapid decline in the species populations over the past two decades. These factors include hunting by local humans for meat, fire and erosion destruction of native habitats, disease transmitted by livestock and competition for food arising from the growing populations of non-native Red Deer (Cervus elaphus). At this time, the remaining populations are found only in the Aysen Region of Chile and in a very small section of adjacent Argentina where their numbers are estimated to be as low as 350 surviving individuals.

Wednesday 12 January 2011 South African Fur Seal - A Gentle Giant

South african fur sealThe South African fur seal (Arctocephalus pusillus) is a friendly and curious animal. These creatures live on the coasts South Africa and both coasts of Australia. They are also known as Cape fur seals, Australian fur seals, or Brown fur seals. Male South African fur seals can grow up to 7 ft (2.2 m) and weigh between 440 and 800 lbs (200-360 kgs). Females are smaller in size with their length going up to 5 ft (1.7 m) and average weight around 260 lbs (120 kgs).

Another way to tell the difference between males and females is their coloring. Males are darker in color than females. Males also have a mane that can show their age as it gets lighter as they get older. South African Fur Seal pups are born black and turn lighter as they get older.

South African fur seals can be found in large groups on rocky or sandy beaches, but they tend to be very independent when traveling. They typically pick rocky islands as their breeding sites in early November. The females are very particular when choosing their mates, basing their decision on how much territory the male candidate claims as his. When males arrive at the breeding site, they fight for territory to impress the females. Pups are born after a 12 month long gestation period. They are weaned over a period of another 12 months with females reaching sexual maturity at 3-4 years and males at 4-5 years.

Even though South African Fur Seal can seem intimidating because of their size, they are remarkably friendly animals. They feel very comfortable in water and even enjoy swimming along with divers. This gives people a great opportunity to bond with these gentle giants. When approached by people on shore, they can get a bit spooked. However, they will not attack. Their main source of food is fish, sometimes crustaceans, or even birds.

South African seals are protected in Australia by the Environment Protection and Biodiversity Conservation Act, passed in 1999, and in Africa by the Sea Birds and Seals Protection Act of 1973. Their greatest threats are great white sharks and orca. You can help spreading the word about this animal by liking it on facebook

Monday 10 January 2011 The Gray Monk Saki - Fruit Thief and Nut Cracker

Gray monk sakiThe Gray monk saki (Pithecia irrorata) is a primate found in South America, primarily in the tropical rainforests of Brazil, Bolivia and Peru. Known for its thick muzzle, a bare face and a curly coat, this arboreal mammal has also been seen in forest patches and drier forests but rarely ventures beyond its home. Although dark in coloring, the Gray monk saki is actually named after the taxonomist who introduced the species in 1842.

Also known as the Bald-faced saki, this omnivorous primate subsists of seeds, leaves, and insects. The multi-layered lowland forests they inhabit promote year-round reproduction of nutrients and foliage, ensuring a constant availability of food. Gray monk sakis are well-known foragers of fruits which are heavily protected by hard casings, such as Brazil nuts. Unripe fruits are even preferred to ripe offerings. Sharp incisor teeth and large canines are used to cut through the shells and obtain the fruit pulp within. Active during the day, the small primate uses all four limbs as it moves through its habitat, leaping vertically from trees, staying within a forested area. A bushy non-prehensile tail, which may grow longer than its head and body combined, is not used for climbing.

Social animals able to interact with neighboring families yet still defend territory when necessary, Pithecia irrorata live in clans. Formed groups can be as large as nine members, including one or two pairs of parents and their young. Monogamous mates communicate with each other by exchanging vocal sounds, employing different pitches to indicate danger or just basic social calls. Pregnancy may happen at any time, during any season. Females give birth to single offspring after a gestation cycle of 180 days, with a weaning period lasting about four months. There is no interbreeding among species of the genus Pithecia.

With a weight range of two and 6.6 pounds (3 kg), males weigh slightly more than their female breeding partners. Female faces have more hair however. The female’s frontal fur is also softer and heavier than a male’s coarse covering.

The Gray monk saki is considered a New World Monkey, with ancestry that dates back to Africa. As an arboreal creature living in trees, Pithecia irrorata do not have natural predators. Not endangered, the greatest threat to their existence is development and the presence of hunters, especially in Bolivia.

Wednesday 05 January 2011 Northern Pika - The Whistle-Blowers of the Wild

Northern pikaNorthern Pika (Ochotona Hyperborea) are remarkable small burrowing animals that are quite similar to a rabbit. They mainly inhabit the southern regions of Siberia, the northern regions of Mongolia, Manchuria, North Korea, and part of Russia and Japan. Commonly found throughout these areas, they are not endangered. Northern Pika prefer damp rain forest habitats that boast rocky formations, suitable for burrowing in and around fallen trees. Their bodies are around 127-186 mm (5-7 inches) long, plus a tail that is 50-120 mm (1-4inches) in length. They are covered in soft reddish-brown fur, and sport hind limbs that are shorter that their front limbs. Males and females resemble each other and can be difficult to tell apart.

Prior to World War II, they were best known for the value of their hide. They were trapped in large numbers for production of a fine felt. With the advent of newer and more economically sound materials, trapping and killing has ceased. Communication occurs by means of a distinct, high whistle that serves multiple purposes. This vocalization is common from males during breeding season, and in between mated pairs. A short and abrupt type of whistle is used to alert others to danger or if predators are spotted. The sound is so unique that it can be used to identify other specific individuals within a group. Their diet consists mostly of grasses, seeds, leaves, and other plant material. Food gathering consists of collecting varied types of vegetation and leaving it in the open to dry out. Once cured, it is then moved to a storage place, where it will accumulate into "hay piles". Mated pairs consume this store of food over the winter.

Northern Pika are also known to consume part of their own feces. It is thought that this is due to the highly digestible energy found in fecal material. During winter, they will dig tunnels into the snow to obtain fresh vegetation. They are a valuable link in the food chain and serve as prey to birds and other native carnivores. The foraging habit of storing supplies of food also provides substance for smaller herbivores, such as deer, who will poach their "hay piles".

Tuesday 04 January 2011 Siberian Musk Deer - A Living Perfume Factory

Siberian musk deerThe Siberian musk deer (Moschus moschiferus) weighs 15-38 lb (7-17 kg). The male of the species has canine teeth that can grow as long as 3 inches (8 cm) and extend below the lips. The short fur varies in color from chestnut to gray. It leans on its acute sense of hearing for almost every situation. Generally, it is a nocturnal creature. Within the area it considers to be home, it uses the same trails that connect its hiding areas, feeding regions, and areas for other activities over and over. It consumes an array of vegetation, including flowers, leaves, young grasses and shoots. It also dines on twigs, lichens and mosses, particularly in the winter season. If food is scarce, then it will chew the bark off a tree or stand on its hind legs to pick leaves. Excluding the female and the young offspring, the deer is solitary except for during the rutting season, at which time females live in small groups. The male leaves the upbringing to the female. Siberian musk deer strongly guard their territory. Male deer mark their territories with scent by rubbing the gland of their tail against stones and trees.

The Siberian musk deer likes to make its home in brushland and forest between altitudes of 8,500 and 11,800’ (2600 and 3600 m). The musk deer can be found in Siberia, northeast China, Mongolia, South Korea, Sakhalin Island, and North Korea. The musk deer population declined by an estimated 50% during the early 1990’s because of high demand for its natural musk, mostly in Japan, China, and Korea. The present population is not known, but it is certainly declining. Currently, the Siberian musk deer is an endangered species.

Overhunting of the male deer for its musk is the main reason for the population decline. Also, males and females that are too young for producing musk get captured in the traps intended for males 3 years of age or older. Disappearance of forest habitat also factors into the decline.

The musk gland of the male is similar in size to a clenched fist, and it is located between the umbilicus of the abdomen and the genitals. The musk from this gland is used to make perfume and soap and also for medicinal purposes in the Far East. The price of musk is high. In 1972 in Nepal, musk cost more than its weight in gold.

Monday 03 January 2011 Bechstein's Bat - The Elusive Whispering Carnivore

Bechsteins batThe Bechstein's bat (Myotis bechsteini) is uniquely difficult to detect, even in its usual broadleaf woodland habitat. This bat especially likes to roost in holes made by woodpeckers or other rock and tree crevices. The sound this species uses for echolocation is so quiet that it is often missed by the special radar equipment used to find bats. This also gives the bat an advantage over its prey as well as its predators. The head and body length of this bat is 4.3-5.3 cm (1.69-2.09 in), the wing span is 25-35 cm (9.84-13.78 in) and the bat weighs 7-14 g (.25-.49 oz). The dorsal fur is light brown, while the ventral fur is pale grey to white. The prominent ears of a Bechstein's bat are small compared to some bats, but they are designed to pick up the slightest whispering of other bats and the faintest sound from its predator or prey.

This bat plays a huge role near the top of the forest food chain, especially pregnant or lactating females who eat two-thirds of their body mass of prey per night. A Bechstein's bat is carnivorous and eats mainly moths, spiders, flies, mosquitoes and beetles. This species flies low and forages for its food off the ground or tree branches.

Females give birth to one offspring in late June and the young bat does not fly until August. During summer males are solitary while females occupy holes in trees and raise their young communally. There is preferential grooming between a mother and her female young, establishing a strong bond among the females.

This species is found in southwest Asia and throughout Europe with the exception of the northern regions. The Bechstein's bat is located mostly in the southern areas of the UK, where it is very rare and named as a priority species for conservation in the Biodiversity Action Plan. Of all the bat species in Europe, the Bechstein's bat is listed for strict protection in the European Council Habitat Directive.

Every member of a woodland habitat is vital to the survival of many others. How do we help preserve this important part of our ecosystem? If we safeguard roosting sites, especially older trees and erect bat boxes in their habitats, we can help maintain existing populations of the Bechstein's bat.
