A short stick, a long stick, and a few stones — all a bit difficult to get to — will help illuminate just how clever wild crows can be, especially when these tools need to be used in a specific order. From the BBC’s Inside the Animal Mind, host Chris Packham observes as a wild crow solves a complicated eight-part puzzle to get to its food: Are crows the ultimate problem solvers?
An animal that can push with 40x their bodyweight, the hairy-tailed mole for example, is definitely something to better understand, and scientists at the University of Massachusetts and Brown University are trying to do just that. So how exactly do moles move so much dirt around as they tunnel underground?
There is an unusual looking monkey called the crested black macaque that is endemic to rainforests in Indonesia, which includes the island of Sulawesi. These striking black primates, sporting punk hairstyles and copper-colored eyes, first caught the attention and won the heart of wildlife cameraman and biologist Colin Stafford-Johnson 25 years ago. But since then, their numbers have dropped by almost 90 percent, so the filmmaker returns to the island to discover why and how he could help.
Upon his arrival, Stafford-Johnson finds a very different looking Sulawesi. An island once entirely covered in forest, is now undertaken with new roads, people and buildings. He meets up with the leader of a team of local biologists — Giyarto, or Ugi for short — who has been studying the macaques for seven years. Together they will make a film to show how special these monkeys are, hoping to involve the local community in protecting them before they disappear forever.
