The best Job in the World? Filming in the Jungle, new from BBC Earth

Often the attraction of working in natural history is the thrill of the wild. The untamed, the undomesticated, the possibility of discovering the unknown! However even as a dedicated natural history program maker, there are certain hostile and remote locations where it is essential to have your super-human senses switched on. As a cameraman, crouching down to get that perfect shot on the dark and damp forest floor. It is your ears you need to rely on above all else, as often the only proof of the vast amounts of animal life around you…is what you hear! The high humidity of this environment creates ideal conditions for the strangest animals to live, breed and sing! Through the cacophony of rival mating calls, warning cries, sharing the location of a known food source and social interaction; the sounds of the wilderness could leave you overwhelmed. But it is a specific sound you are listening out for… As an enthusiastic drummer of the jungle, the chimpanzee has worked out a less stressful way of communicating with each other than exhaustive calls...which transpires is also a highly enjoyable one! While scouring the forest in search of their next meal, the troops will use buttress roots and hollow trunks to sound out! Drumming as they pass, the chimpanzee’s will make distinctive bass sounds (some even repeatedly on their favorite trees!) using their hands and feet to make clear - who is where, and how successful each party has been with their search.

Incredible rites of passage: Scarred for life, new from BBC Earth

With a dangerous reputation, crocodiles would not be the first animal you would associate with mental and physical strengthening. Surprisingly, the people of Papau New Guinea have a connection between man and beast that marks a boys journey into adulthood. Many traditional celebrations that accompany events like birth, the start of adolescence, marriage, and death are richly integrated with the use of natural materials; such as feather, skin and bone. But when an occasion as serious and important as the coming of age beckons, the rituals connection between cause and effect must reflect this intensity. Many inhabitants of the South Pacific islands practice some form of physical transformation during male adolescence. The sacred act of scarring which people of the Solomon Islands practice can make rituals such as ceremonial hair cutting, and being cast into the wilderness for a short period seem relatively less challenging. For decades, tribes have used the tradition of scarification to mature their young boys into men. For a number of weeks, the boys psychological as well as physical barriers are pushed with consistent verbal taunts as well as public humiliations. However their discipline is yet to be tested to its breaking point.

With a list of predators as long as your arm, it's not surprising that they have developed a way of breeding which ensures their survival. Ecological biomass is a term used to describe how living biological organisms group together to defend their species against the many predators they face, there is after all power in numbers! This isn't an uncommon technique, and we see similarities in the breeding habits of many animals, particularly those who live in herds.

Fish and Wildlife Service Removes Endangered Species Act Protection From Arizona’s Desert Nesting Bald Eagles

The U.S. Fish and Wildlife Service is acting to remove Endangered Species Act protection from Arizona's desert nesting bald eagles. Almost two years after U.S. District Court Judge Mary Murguia’s March 5, 2008 rejection of the agency's last attempt in 2007, a similar decision by Fish and Wildlife has been released for publication in tomorrow's Federal Register. Today the agency also filed a request with the U.S. District Court to remove an injunction currently in place to protect the eagle. "We conclude that the best information available does not indicate that persistence in the ecosystem of the Sonoran Desert Area is important to the species as a whole," the new Fish and Wildlife decision states.
