European Marmot



The European marmot (Marmota marmota) is a species of marmot found only in Europe. It is also known as the alpine marmot.


Physical Features
The European marmot has a stocky body.  They weigh about 3 to 4 kilograms.  These animals measure about 20 inches (52 cm) excluding their tail.  Their tail measures about 8 inches (20 cm).  The European marmot generally has short and muscular legs.  Their fur is golden-brown in color.  This species of marmot has a short tail.  The European marmot is the largest squirrel species.


Taxonomy
The European marmot belongs to the squirrel family of Sciuridae.  They belong to the order of Rodentia.


Behavior
European marmots are diurnal. They rest at night but are active in the day.  European marmots hibernate for approximately 7 months a year.  They produce a shrill whistle when they are alarmed.  They even growl and screech when they are angry.


Distribution and Habitat
The European marmot is found in the alpine regions of Switzerland, France and Italy.  They have been re-introduced to the Carpathian Mountains which is located on the border of Slovakia and Poland.  They are also found in parts of Germany.  They live in alpine meadows and in rocky slopes with an elevation of about 1,970 feet (600 meters).  They build burrows which are very complex, digging with their forepaws, while their hind legs also help in digging.  Their forepaws will scrape away the soil and the hind legs will keep the soil aside.  Each burrow will have only one family which has a dominant breeding pair.  The same burrow may be used by the next generation.  While digging the tunnel, the European marmot will sometimes use its teeth to remove some small stones.


Diet
A European marmot in summer.
European marmots are omnivores.  They will eat plants such as herbs and shrubs.  Spiders and other insects are also eaten by these marmots. European marmots will prefer to eat tender and young plants of any species.  They hold their food in their forepaws while eating.  Before hibernating in winter, they eat a lot a food which provides them with fat.


Conservation Status
European marmots are not threatened at the moment.  They are abundant in their current range. Their population had declined in the 20th century, but now they have successfully been re-introduced to the respective range.

Queen Alexandra's Birdwing


The Queen Alexandra's Birdwing (Ornithoptera alexandrae) is a butterfly found in Papua New Guinea.  It is the largest species of butterfly and was discovered by Lord Walter Rothschild and he named it after Queen Alexandra.  It is currently rated as 'Endangered' by the IUCN.


Physical Features
Queen Alexandra's Birdwing is the largest butterfly in the world.  Females are bigger than males.  They have rounder and broader wings than males.  The wingspan of females can measure about 1 foot (12 inches).  Females mostly have brown wings with white markings.  Their body is a type of cream-color.  They have a small part in their thorax which is covered with red fur.  These butterflies can have a body length of 6cm to 8 cm which is quite big for a butterfly.  They can weigh about 15 grams.  Males have a wingspan that mostly measures 17 cm (7   inches).  There is a type of Queen Alexandra's Butterfly which has golden spots on its wings.  This type is considered as the most spectacular type of this species.

Diet
The Queen Alexandra's Birdwing, as a caterpillar, feeds on a toxic pipevine plant called Aristolochia schlecteri.  When the Queen Alexandra's birdwing, as butterflies and caterpillars, eat this pipevine, they themselves become poisonous to digest. This is protects them from predators who intend to eat them. A newly emerged larvae will eat its own eggshell before feeding on foliage.  An adult will feed on nectar from flowers.  


Distribution and Habitat
Queen Alexandra's Birdwing is located only in a small part of Papua New Guinean rainforests.  It is found in Popondetta in the Oro Province.  It is restriceted to 100 kilometers of rainforest.


Life Cycle
A Queen Alexandra Birdwing as a caterpillar 
This species of butterfly lays about 27 eggs during its entire life span.  It takes about six weeks for the egg to hatch and develop into a pupa.  The butterfly's pupal stage lasts for a month or more.  An adult butterfly will emerge from the pupa in the morning, when the humidity level is high.  This prevents their wings from drying up.  A Queen Alexandra's Birdwing may live for three months as an adult. 


Conservation Status
The Queen Alexandra's Birdwing is rated as 'Endangered'  by the IUCN.  It is hunted as it is considered to be a great prize by many hunters.  It is found only in 100 kilometers of rainforests.

Greater Bilby


The greater bilby (Macrotis lagotis) is an nocturnal omnivorous mammals found in Australia.  They are rated as 'Vulnerable' by IUCN.  Their range and population are decreasing every year.


Physical Features
Greater bilbies are about 29 to 55 cm (11 inches to 22 inches) in length.  Males weigh about 1.5 kilograms to 2.7 kilograms.  Females weigh 700 grams to 1 kilogram.  There are specimens of males that weigh about 4 kilograms.  Bilbies look like bandicoots.  There are few differences between bilbies and bandicoots.  Bilbies have a longer tail, bigger ears and silkier fur.  Bilbies have an excellent sense of hearing due to their big ears and even have sharp hearing.  Their skin is bluish grey with white or tan patches.  They have strong forelimbs and thick claws which helps them in digging burrows.  Bilbies have one of the shortest gestation period of any mammal.  Their gestation period is 12 to 14 days.


Habitat
Burrows made by a Greater Bilby
Greater bilbies were once widespread in arid and semi arid regions.  Now they are restricted to arid wastelands.  They dig spiral burrows which keeps them cool in the deserts.  This prevents predators from eating them.  Bilbies prefer this habitat as spinifex and shrubs grow there, making it easy to get food.


Diet 

Bilbies are omnivores.  They will eat insects, bulbs, larvae, seeds, fruits and fungi.  They do not need much water as they obtain moisture from the food.  They catch insects using their long tongues as insects will be found in small burrows.


Conservation Status
Greater bilbies are becoming endangered.  They are becoming vulnerable to the domestic cats introduced to their habitat.  People even kill them for their fur.  The country has started reintroducing some population to different regions but it still remains vulnerable.


Distribution 
Greater bilbies are only found in Australia.  They are found in parts of Western Australia and Northern Territory.  A small part of Queensland is inhabited by these animals.

Jaguarundi



The Jaguarundi (Puma yagouaroundi) is a species of cat found in North and South America.  Because of the different color phases, people used to think that there were two different species: the grey one being called jaguarundi and the red one being called eyra.


Physical Features 
The jaguarundi is a medium sized cat.  In terms of physical appearance, it is the least cat-like of all felines and cats.  It has a long body, short legs and a long tail which makes it look like a otter or sometimes a marten.  As they look like an otter, they are sometimes called 'otter cats'.  They do not have any spots on their body and their color is same throughout or sometimes it may have some faint markings on the underside and face.  It has a total length of 54 to 74 cm out of which the tail is 32 to 52 cm long.  It weighs about 4.2 kilograms to 10.3 kilograms.  Jaguarundis can be brownish grey (grey phase) and foxy red to chestnut (red phase).


Behavior and Diet 
Jaguarundis are mainly diurnal, being active during mornings.  They normally hang around on trees but prefer hunting on ground.  They will almost eat any animal they catch like rodents, small reptiles and even ground feeding birds.  Jaguarundis may even eat larger pray like rabbits and some primates like marmosets, which is unusual for a wild cat. Like all cats, their diet consists of a small amount of vegetation of arthropods like scorpions.  Jaguarundis are rather cordial than other wild cats.  They can tolerate close presence of other animals.  They are usually found alone as they lead a solitary life.  Jaguarundis are shy and very cautious of man made traps.     



Distribution and Habitat
Range of  jaguarundis
Jaguarundis are found in North and South America.  In North America, they are found from southern Texas to coastal Mexico.  Their range runs through Central America and then into South America, where they are found east to the Andes.  Their range goes on till northern Argentina in the south of South America.  Jaguarundis prefer to live in lowland brush areas which has water nearby.  There are some sightings of them on elevations of 3200 meters high (10500 feet).


Conservation Status
Jaguarundis are not under any threat as of now.  They are rated as 'Least Concern' by IUCN.  They have a very wide range and therefore are not under threat.
