The Zanzibar Island, experience unchanged history

Although there’s more to the islands of Tanzania than just Zanzibar, Zanzibar enchants and fascinates with its oriental mystique and forgotten exoticism -- the very name evokes the Spice Islands and the dhow trade, sultans and palaces built of limestone and coral against the palm trees and the crashing surf.

Zanzibar’s coastline offers some of the best beaches in the world, but sand and surf vary depending on what side of the island you’re on. On the east coast, waves break over coral reefs and sand bars offshore, and low tide reveals small pools of starfish, small minnows, and anemones. Up north, ocean swimming is much less susceptible to the tides, and smooth beaches and white sand make for dazzling days in the sun.

Portuguese invasion and control of the Swahili Coast in the late 16th century ended the golden age of the archipelago, although the Omani Arabs returned to power less than a century later. The port city of Stone Town dominates the west coast, and although the beaches of Mangapwani, where slave caves are visible at low tide and nearby Bububu are less than half an hour’s drive away, a night or two spent on the east or north cost is well worth the extra hour it takes to drive there. That said, the Chole Island Marine Park just off Stone Town – and nearby Prison, Grave, and Snake Islands – make a refreshing day-trip and a good break from exploring the winding passageways of the old city.

On the south coast of Zanzibar lies the Menai Bay Conservation Area, a sea turtle protection area for the endangered species that come to breed on the island. Roads to the southeast coast take visitors through the Jozani Forest, home to Zanzibar’s rare Red Colobus monkeys and a number of other primate and small antelope species.

Today, many of the winding streets and high town houses of old Stone Town remain unchanged and you can walk between the sultan’s palace, the House of Wonders, the Portuguese fort and gardens, the merchants’ houses, and the Turkish baths of the old city. Day-long spice tours to working plantations offer visitors the chance to observe the cultivation of cloves, vanilla, nutmeg, cinnamon, and other spices that have made the island famous.

Western Lowland Gorillas on the Rise

Western lowland gorillas are endangered, but they remain far more common than their relatives, the mountain gorillas. They live in heavy rain forests, and it is difficult for scientists to accurately estimate how many survive in Cameroon, Central African Republic, Congo, Equatorial Guinea, Gabon, Angola, and the Democratic Republic of Congo.

A new tally of lowland gorillas has found massive and surprising numbers of these African primates alive and well in the Republic of Congo, Wildlife Conservation Society scientists announced.

The new census puts the number of western lowland gorillas (called great apes, along with chimpanzees, bonobos and orangutans) within two adjacent areas in the northern part of the Congo at 125,000 individuals, including infant gorillas.

Previous estimates from the 1980s placed the entire population of western lowland gorillas, which live in seven Central African nations, at fewer than 100,000 individuals. Since then, scientists thought the number would've at least halved due to hunting and disease but last year’s census was a surprise to many.

Western lowland gorillas tend to be a bit smaller than their mountain cousins. They also have shorter hair and longer arms.

Western lowland gorillas are one of four recognized gorilla sub-species, along with mountain gorillas, eastern lowland gorillas and Cross River gorillas. While the eastern lowland gorilla is considered endangered by the International Union for Conservation of Nature (IUCN), the others are labeled "critically endangered," which means the group faces an extremely high risk of extinction in the wild.

Gorillas can climb trees, but are usually found on the ground in communities of up to 30 individuals. These troops are organized according to fascinating social structures. Troops are led by one dominant, older adult male, often called a silverback because of the swath of silver hair that adorns his otherwise dark fur. Troops also include several other young males, some females, and their offspring.

The leader organizes troop activities like eating, nesting in leaves, and moving about the group's three-quarter- to 16-square-mile (2- to 40-square-kilometer) home range.

Those who challenge this alpha male are apt to be cowed by impressive shows of physical power. He may stand upright, throw things, make aggressive charges, and pound his huge chest while barking out powerful hoots or unleashing a frightening roar. Despite these displays and the animals' obvious physical power, gorillas are generally calm and non-aggressive unless they are disturbed.

Female gorillas give birth to one infant after a pregnancy of nearly nine months. Unlike their powerful parents, newborns are tiny—weighing four pounds (two kilograms)—and able only to cling to their mothers' fur. These infants ride on their mothers' backs from the age of four months through the first two or three years of their lives.

Young gorillas, from three to six years old, remind human observers of children. Much of their day is spent in play, climbing trees, chasing one another, and swinging from branches.

In captivity, gorillas have displayed significant intelligence and have even learned simple human sign language.

In the wild, these primates are under siege. Forest loss is a twofold threat; it destroys gorilla habitat and brings hungry people who hunt gorillas for bush meat. Farming, grazing, and expanding human settlements are also shrinking the lowland gorilla's space.

Together, let’s save the gorillas for posterity.

The Bat-eared Fox

The Bat-eared Fox (Otocyon megalotis)with the name Otocyon which is derived from the Greek words "oto" for ear and "cyon" for dog is a canid of the African savanna, named for its large ears. The ears of bat-eared foxes can grow up to 5.3 inches long and have an average weight of about 2.2-4.5 kg.

The teeth of the Bat-eared Fox are much smaller than teeth of other canid species. This is an adaptation to its insectivorous diet, insects making up as much as 80% of its food intake.Bat-eared foxes use these specialized ears to locate termites, dung beetles, rodents, birds ,eggs and sometimes fruits and other insects, which make up most of their diet. Bat-eared foxes can hear larvae chewing their way out of an underground dung beetle ball. They can also detect the sound of harvesting termites chewing on short grasses. Surviving on an all-insect diet required several adaptations in the bat-eared fox. In addition to their large and powerful ears, bat-eared foxes have specialized extra teeth for chewing up insects, and their lower jawbone is designed to open and close rapidly.

The body of the bat-eared fox is ashy gray in color with black limbs and tail. The backs of its enormous ears are also black, and it has a raccoon-like white facemask. The underside of its neck and belly are paler than the rest of its body.

Bat-eared Foxes are mostly nocturnal animals that live in small groups consisting of mated pairs and their young. The pairs live in dens and typically raise two to five pups together. Mated pairs are very social and are monogamous, Bat-eared foxes mate for life, and sometimes two females will mate with one male and share a communal den. The father is very invested in the rearing of young, and he spends a great deal of time baby-sitting. While the father is watching the cubs, the mother is free to forage for food, including insects, which are a steady food source. Though they are low in nutrition and cannot be regurgitated for the young, they allow the mother to take in the necessary amount of food needed to produce milk for the cubs.

Bat-eared foxes are hunted by several different mammal species, including cheetahs, jackals, spotted hyenas, rock pythons, African wild dogs, and leopards. Their large, bushy tails work as a rudder when fleeing from predators in a zig-zag pattern. They are fast and good at dodging, but their best chance at escaping predation is by fleeing to their underground dens, which have several entrances and multiple chambers connected by tunnels. A bat-eared fox family may have several dens throughout their home range.

Bat-eared foxes are also preyed upon by raptors and must keep a watchful eye while foraging. Most of their foraging is done alone at night. While looking for food, these foxes walk slowly and quietly with their noses to the ground and their ears cocked forward, listening for insects.

Look for them when outdoor, usually in the morning hours, they can be seen warming up in the morning sun, before getting into their dens when it gets hot.
