Another reason to marvel at dolphins. As a follow up to the previous blog on dolphins calling each other by name, new research from Dr. Jason Bruck at the Institute for Mind and Biology (University of Chicago) shows that dolphins have the longest memory known in animals. In addition to Kai, shown above, a dolphin named Bailey recognized the whistle of Allie, even though they had not seen each other in more than 20 years! I am fairly certain I…

A new study published in the Proceedings of the National Academy of Sciences provides evidence that bottlenose dolphins (Tursiops truncatus) use "signature whistles" to identify and call each other by "name".
Dr. Vincent Janik at the Scottish Oceans Institute, University of St. Andrews and colleagues recorded the individual whistles of wild bottlenose dolphins traveling in groups (pods). Using the recordings, they developed computerized versions of the whistles that were missing the vocal characteristics of…

That's exactly the sort of flight that they undertake when they're alarmed, and other pigeons treat the resulting whistles as cues to take to the skies themselves.
Crested pigeons are comical-looking birds that are…
