Cats

catWhy do Cats Eyes Glow in the Dark?

Cats movearound at night, so they must be able to see in the dark. Where humans cannothing at all, cats can still see. A cat’s eye take in the tiniest bit oflight. Inside the eye the light is reflected backward and forward. That is thereason that their eyes glow brightly in the dark. The pupilof cats’ eye change to control the amount of light that enters the eye. Theynarrow to tiny slits in bright sunlight but widen to large orbs when it isdark. That is why cats see so well in the dark. In addition there is an areabehind the retina that reflects light, and that is why cats’ eye appear to glowin the dark.

Citron-Crested Cockatoo

Citron-Crested-CockatooThis is a large, white parrot with anorange crest and light orange ear spots. The feathers under the wing and tailare yellow, and the beak is hooked.

FUN FACTS
  • These birds are often regarded as pestsbecause of their diets (sometimes feeding on crops); licensed culling ispermitted in certain states.
  • Both parents take part in incubatingthe eggs.       
  • Cockatoos can mimic the sounds of otheranimals, including people.         
  • Cockatoos can hold their food in onefoot and break pieces off of it with the other foot.           
  • Cockatoos live in small loose flocks.           
  • They are very gregarious and quicklylearn to mimic. These birds also have a very shrill cry.          
  • Thesebirds are thought to be one of the rarest parrots on Sumba Island.In 1993, studies estimated citron populations to be 1,150-1,850 individuals.

Colobus

colobusDESCRIPTION: A small monkey with a U-shaped mantleof long white fur that descends from its shoulders and around its back. Whitefur surrounds their black face

FUN FACTS:

  • Baby colobus' are born completely white.
  • Ruminant-like digestive system hasenabled leaf-eaters, such as colobus', to occupy niches that are inaccessibleto other primates.
  • They live in territorial groups ofapproximately nine individuals, based upon a single male with a number offemale and their offspring.
  • The Old Worldmonkeys of the subfamily Colobinae have a specially adapted stomach that issacculated and supports bacterial colonies. These bacteria make it possible fordigestion of cellulose in their diet of leaves, unripe fruit, and seeds.
  • There are documented cases of"allo" mothering, which means members of the troop other than theinfant's biological mother care for it.
  • The differences between monkeys andapes are easy to see once you know what to look for. Apes do not have a tailand are generally larger than most other primates. They have a more uprightbody posture as well. Apes rely more on vision than on smell and have a shortbroad nose rather than a snout, as Old Worldmonkeys do.
  • OldWorld monkeys are generally from Africa and Asia while New World monkeys arefrom the Americas.In Old World monkeys, the nostrils facedownward and are narrow. New World monkeyshave round nostrils facing to the side. Old World primates are usually largerthan New World's. Many of the Old World monkeys are partly terrestrial.

Crane

craneDESCRIPTION: Large, long-legged birds, straightbills, long necks and elevated hind toe, bare pink or red and white cheekpatch, golden feathery 'crown' protruding from back of head. FUN FACTS:
  • Unlike most cranes, crowned cranes lackfolds in their windpipes making their voices very different from other cranes.
  • Crowned cranes occasionally roost intrees, a trait not seen in other cranes.
  • Thesecranes are often considered the living fossils of the crane family. They wereable to survive the Ice Age in the savannas of Africa.

Dogs

dogWhy do dogs Bark at Strangers?Long agodogs lived in packs. If a stranger came around, one dog would bark and warn theothers, and they would attack the stranger. Your dog thinks of you as one ofits pack.

If astranger comes near you or your home your dog will bark to keep him away.

A dog thatis chained up has a very small home ground and will guard it even morefiercely. That is why it barks so loudly at strangers.

Dolphins

dolphinsScientistsbelieve that large marine mammals like whales and dolphins have brains muchlike those of humans. They are able to communicate, follow instructions, andfigure things out.
Mammalshave larger, more well-developed brains than other animals. Most mammals havegood memories and are able to learn new things. This means that mammals canlearn to survive in new situations and in new places if they need to. This iscalled adapting.

 

Eagle

eagleSIZE:   Most eagles are large in size, 60-90 cm in length with a 1.8 m wingspan. The Americanharpy eagle is the largest of all the eagles, with length of 110 cm and a 2.4 m wingspan.
FUN FACTS:
  • Eagles areoften further divided into four categories depending on diet and physicalfeatures. Some examples include:
  • true or booted eagles -"booted" is a reference to the leg feathers, which extend all the waydown to the toes. Golden eagles (Aquila chrysaetos)are a type of true or booted eagle.
  • harpy eagles - the six types of harpyeagles can be identified by the crests on their heads.
  • fish eagles - diet is mainly fish.Bald eagles (Haliaeetus leucocephalus) are a type of fish eagle, but their dietalso consists of birds and small mammals. In addition, bald eagles arescavengers that harass other birds and steal their fish.
  • snake eagles - diet includes avariety of snakes. Bateleur eagles (Terathopius ecuadatus) are snake eagles

Eastern White-Bearded Wildebeest

white-bearded-wildebeestDESCRIPTION: This subspecies of wildebeest has awhite beard, unlike most other subspecies which have black beards; both sexeshave smooth, cowlike horns.
SIZE: Male - 1.25-1.45 m at the shoulder.Female - 1.15-1.42 m at the shoulder
WEIGHT:  Male - 165-274 kg. Female - 140-230 kg
FUN FACTS:     
  • Each yearan ancient spectacle, the single largest movement of wildlife, begins.White-bearded wildebeest migrate in search of fresh pastures and water. Suchmigrations may contain as many as one million individuals. Up to halfa million plains zebra and Thomson's gazelles often travel with the gnus. InNovember, the rains have resumed in the south and the green grasses of theNorth are depleted, the masses surge back to the fresh pastures. Thismigration takes the form of long columns, stretching thousands of miles.Visitors and natives say the ground trembles under their stampeding hooves. Predatorssuch as lions and hyenas follow the herd while crocodiles wait hungrily in therivers. They wait for a lone unhealthy gnu or youngster to break away from theothers; wading into a herd of over one million hoofed animals for a meal is toodangerous.
  • Wildebeests live in more densely packedherds than any other large mammal, except for humans.
  • Eighty percent of calves (sometimes upto half a million) are born within a 2-3 week period at the start of the rainyseason. Since predators can only take a limited number of prey at any giventime, there is a higher chance of survival for each individual calf.
  • Calves can stand and run within 3-7minutes after birth. They follow their mothers as they move with the herd.
  • At nightwhite-bearded wildebeest sleep on the ground in rows; this provides them withthe security of being in a group while allowing them space to run in case of anemergency

ElectricRay

electric-raySIZE: Atlantic torpedo ray may be up to 1.82 m in lengthIn general, female rays are larger thanmales.
WEIGHT: Atlantic torpedo ray may reach 90 kg
FUN FACTS:
  • Electric rays belong to the superorderBatoidea, which includes stingrays, skates, guitarfishes, and sawfishes. Liketheir relatives the sharks, batoids have skeletons made of tough connectivetissue called cartilage.
  • Atlantic torpedo rays (Torpedonobiliana), for example, live along the coastlines of Canada, the UnitedStates, United Kingdom,and South Africa.But they also have been found in the open ocean at depths of approximately 450 m. Blind electricrays (Typhlonarke aysoni) have been discovered in waters as deep as 900 m.
  • The mouth of the Australian coffin ray(Hypnos monopterygium) is enormous, allowing it to gulp prey half the size ofits body.
  • All livingcreatures produce electricity - even humans - but electric rays have twospecial kidney-shaped organs that generate and store electricity like abattery. Large Atlantic torpedo rays can generate enough power to produce ashock of about 220 volts, while smaller rays, like the lesser electric ray(Narcine brasiliensis) can only muster a shock of about 37 volts.
  • Most electric rays bury themselvesunder sand during the day and come out at night to feed. If prey isencountered, the ray will stun the creature with electricity. Then, the raywill guide the food with its pectoral fins to its mouth, which is located underits body.
  • Inaddition to stunning potential prey and dissuading prospective predators, theelectric organs of electric rays may also be used to detect prey and tocommunicate with each other.

Flamingo

flamingoDESCRIPTION: The Chilean flamingo is a tall, largebodied bird with a long neck and small head. Most flamingos, including thisspecies, have pale pink plumage and bills. This subspecies of flamingo isslightly smaller than the Caribbean flamingoand has gray legs with pink bands at the joints.
FUN FACTS:
  • In many languages, the word flamingo(originally derived from the Portuguese language meaning 'red goose') is areference to their flying style formation and the noise they make.
  • All flamingos feed with their billsupside-down. They tip their head into the water and filter feed, using specialhair like adaptations in the top half oftheir bill, to gather themicroorganisms that make up their diet.
  • Flamingos are an ancient group ofbirds. Their fossil records dates back to the Miocene epoch, which is about 10million years ago.
  • Flamingos are not born with theirbeautiful pink plumage. Their color comes from the carotenoid pigments theyconsume as part of their diet. Some scientists believe that a flamingo'ssuccess in breeding relies on its bright color.
  • Both the male and female make the nestsby scooping mud together with their feet and bill.
  • Both male and female adults, providetheir young with a type of milk called crop milk.
  • Likeother South American flamingos, these birds are able to endure coldtemperatures.
