  • Orangutan swimming and he loves it

    For many years, zoos have used water moats to confine chimpanzees, gorillas and orangutans. When apes ventured into deep water, they often drowned. Some argued that this indicated a definitive difference between humans and apes: people enjoy the water and are able to learn to swim, while apes prefer to stay on dry land.

    But it turned out that this distinction is not absolute. Renato Bender, who was working on a PhD in human evolution at the School of Anatomical Sciences at the University of the Witwatersrand (Wits University), and Nicole Bender, who worked as an evolutionary physician and epidemiologist at the Institute of Social and Preventive Medicine at the University of Bern, have studied a chimpanzee and an orangutan in the US. These primates were raised and cared for by humans and have learnt to swim and to dive. Their findings have been published online on 30 July 2013, in The American Journal of Physical Anthropology.

    Perhaps this ability to learn to like water and learn to swim, requires zoos to reconsider the common approach to confine these Great Apes in outdoor enclosures by water-filled moats. Although, until now gorillas in zoos broke out of their enclosure by jumping the surrounding - apparently too small - water-filled moats, but swimming across the moat to escape has not been documented yet.

    The orangutan Suryia, who was filmed in a private zoo in South Carolina, also possesses this rare swimming and diving ability. Suryia can swim freely up to twelve meters.

    Suryia the orangutan swims with his limbs alternately forwards and backwards. These movements are highly divergent from swimming movements known from other primates. The researchers believe that this swimming style might be due to an ancient adaptation to an arboreal life. Most mammals use the so-called dog-paddle, a mode of locomotion that they employ instinctively. Humans and apes, on the other hand, must learn to swim. The tree-dwelling ancestors of apes had less opportunity to move on the ground. They thus developed alternative strategies to cross small rivers, wading in an upright position or using natural bridges. They lost the instinct to swim. Humans, who are closely related to the apes, also do not swim instinctively. But unlike apes, humans are attracted to water and can learn to swim and to dive.

  • Chimpanzee diving into the water and loves it

    The researchers were extremely surprised when the chimp Cooper dived repeatedly into a swimming pool in Missouri and seemed to feel very comfortable. To prevent the chimp from drowning, the researchers stretched two ropes over the deepest part of the pool. Cooper became immediately interested in the ropes and, after a few minutes, he started diving into the two-meter-deep water to pick up objects on the bottom of the pool. Some weeks later, Cooper began to swim on the surface of the water.

    Watch Cooper the chimp repeatedly made full submersions in deep water holding on to one or two ropes, often trying to grasp with one foot or one hand objects placed 2 m deep on the floor of the pool. He also is covering his eyes during the dives.

  • Red-tailed laughingthrush having a bath inside the Bird House at Basel Zoo

    The walk-through Bird House at Basel Zoo comprises free flying bird species besides several caged individuals (such as guira cuckoo and Swainson's Toucan). The small integrated aviaries along the walls are not too bad either, but the enormous tropical house and its vegetation is like a little jungle where you can sit and wait for some of the most beautiful bird species to appear at feeding spots or little ponds. The building style of the Bird House reveals that the inside once comprised rows of aviaries and not free-flying birds as it does today. In fact, since the 1950s the numerous traditional aviaries have been gradually removed and the bird species added to the walk-through exhibit. Several of the larger bird species, such as the kookaburra, have access to an outdoor aviary as well.

  • My Dub siren now has a synth option

    I've just had a go at adding a synthio based mode to yesterday's Dub siren (see https://v.basspistol.org/w/pS4PrN9Wjo5eFP4hqFSpYr).

    The switch now sets the siren to sample mode in its left position and to synth mode in the middle position. I may add another synth mode in the future.

    The big knob on the left sets the LFO frequency of the siren, while the encoder to its right now selects the waveform, from ramp up, sine, saw and square.

  • The voluntary 'One-Sea-Lion-show' at Berlin Zoo

    This is one sea lion who likes to be in the centre of attention and does not want to share the audience with its peer. Beware, this is a voluntary performance, although the California sea lion cannot hide its irritation when a leaf gets stuck in its mouth or is this part of the show too?
