Three bottlenose dolphins were released into the open sea in Indonesia Saturday after years of being confined for the amusement of tourists who would touch and swim with them. As red and white Indonesian flags fluttered, underwater gates opened off the island of Bali to allow Johnny, Rocky and Rambo to swim free. The trio were rescued three years ago from their tiny pool in a resort hotel to which they had been sold after spending years performing in a traveling circus. They regained their health and strength at the Bali sanctuary , a floating pen in a bay that provided a gentler, more natural environment.

Male bottlenose dolphins form the largest known multi-level alliance network outside humans, an international team led by researchers at the University of Bristol have shown. These cooperative relationships between groups increase male access to a contested resource. The scientists, with colleagues from the University of Zurich and University of Massachusetts, analysed association and consortship data to model the structure of alliances between 121 adult male Indo-Pacific bottlenose dolphins at Shark Bay in Western Australia. Their findings have been published in The Proceedings of the National Academy of Sciences (PNAS). Four male allies and a female dolphin.

They are New York City’s nearshore bottlenose dolphins (Tursiops truncatus) that return to feed in local waters from spring to fall each year, and a team of scientists led by the Wildlife Conservation Society (WCS) is tracking them. The team deployed underwater listening devices at six locations off Brooklyn, Queens, Staten Island and New Jersey, to detect where and when dolphins fed. Dolphins produce a series of rapid clicks called “foraging buzzes” which can reveal feeding activity. They found that feeding was generally highest in late summer into autumn, but it peaked at different months at different sites. Varia...
