Orange-breasted Sunbird



The beautiful Orange-breasted Sunbird Anthobaphes violacea is endemic to the fynbos of southwestern South Africa, but also occurs in parks and gardens. Often tame and quite approachable (especially in eg Botanic Gardens), the Orange-breasted Sunbird is a common breeder across its limited range, and an altitudinal migrant moving to to higher altitudes during the southern summer in search of flowers.

The Orange-breasted Sunbird is associated with Ericas (commonly known as ‘heathers’ in the UK), from which it takes nectar, insects (often caught in flight) and spiders. Unmissable at Kirstenbosch Botanic Gardens, even a short visit here will bring good views of these stunning birds - often seen first of all as they rocket overhead chasing each other giving loud “click” calls.

Galapagos Sea Lion

Order: Carnivora
Family: Otariidae
Scientific name: Zalophus wollebaeki
Name in Spanish: Lobo Marino Galapagos sea lion hair.
Distribution: Galapagos Islands and several islets. It was reported that a colony of Isla de la Plata.

Some individuals of these species are endemic to our enchanted islands, are often carried by ocean currents and arrive on the mainland, where they are for seals, keeping the animals in order to clarify the way, are not part of our wildlife. The Galapagos sea lions are also known as "wolf hair, as is the length of the hair in the whole body evenly. Males have a crest and is about 250 kg, females reach 110 kg. The coat color varies from gray to dark brown depending on age and gender.

Sea lions are polygamous, the male keeps a harem of women in the territory of an aggressive defense, both on land and at sea, they eat fish, squid and other marine invertebrates and in turn prey for sharks and whales (Orcas).

They are likely to disappear in the event of epidemics or natural disasters. Although currently most of the animals, people threaten Galapagos have introduced (they can transmit diseases to their capture or their children), so often caught accidentally in fishing nets, as bait for shark fishing, and intoxicated by the increase in the costs used for the garbage.

Coelacanth

Life on Earth since the era of Devonia about 380 million years ago and did not evolve. This is older than dinosaurs (200 million years ago). In the world there are two species (Latimeria chalumnae and Latimeria menadoensis). L. species chalumnae was first discovered in the Comoros Islands, Africa, in 1938. L. species menadoensis first discovered in Manado, North Sulawesi, in 1998.
The experts thought the coelacanth was extinct since 10 million years ago.

This fish lives at depths of 150-200 meters at a temperature of 12-18 degrees Celsius in the recesses of caves lava rock. A carnivore is a predator with prey on small fish at night.Coelacanth is placed parallel to the air-breathing fish species in the lungs (Lungfish) and primitive amphibians in the family tree bony fishes. Coelacanth eggs hatch in the stomach, but not classified as marine mammals.
There are still many things not known about these fish because of extremely rare. Its body structure has a belly fins (pectoral), pectoral fin (pelvic), anal and fell back like a human hand. Its length can reach 1.5 meters and weigh 40 kg.

The Peregrine Falcon [Falco peregrinus]

Unlike the other species that I researched on the WEB, the Peregrine Falcon is treated with seriousness almost everywhere I visited. Perhaps this is because Peregrines, the worlds swiftest birds, are endangered in Canada and in many places in the United States.

Like the Whooping Crane, the Peregrine Falcon connects people throughout Canada and the United States, but even moreso, in the cause of protecting and reestablishing them. And, uniquely, there are pages to visit that show live viewing of their nesting sites in several North American cities.

I also found that there are many centres in Canada and the United States devoted to the recovery of the endangered raptors [birds of prey] including the Peregrine Falcon. Many committed individuals, sometimes assisted by governments, but mostly surviving on small, inadequate budgets, are doing what they can to ensure that these marvelous, swift-winged predators remain in our world. Not surprisingly, I discovered that they can use our support!

Food: Peregrines can reach speeds close to 320 km-h in a downward dive. They use their speed and agility to catch birds in mid-air. Their prey range in size from sparrows to large waterfowl such as ducks.

Bilby

Bilby bandicoot muzzle characteristic long ears and very long. They are about 29-55 cm in length. Compared with bandicoots, they have a longer tail, bigger ears, and soft, silky fur. The size of the ears, full version of them have a better hearing. They are nocturnal omnivores do not need to drink water because it moisture they need from their food, like insects and their larvae, seeds, spiders, onions get, fruits, mushrooms and small animals. Most food is found by scratching or digging the soil, and their language is very long.

Unlike possums, they are excellent burrowers and build systems of narrow tunnels with their front legs strong and well developed claws. A Bilby make a rule, a number of tubes in his home area, to about a dozen, and moves between them, for both protection from predators and the heat of the day. The cover Bilby female faces back, which prevents the bag to fill with dirt while she is digging.

Bilbi have a very short gestation period of about 12 bi
