Picture-Sorting Dogs Show Human-Like Thought

ComputerDog writes "A new study shows they can sort photographs into categories in a similar way to humans. In experiments, dogs were shown photographs of a landscape and of a dog, and were rewarded if they selected the latter using 'a paw-operated computer touch-screen'. Later they were able to correctly categorize dogs shown on an unfamiliar background landscape. '' "

Birds

[Tablizer]

I saw a show on a Discovery-like channel in which during WW2 they successfully trained birds to recognize different makes of vessels and peck a steering panel in the right direction. They were trying to build a guided bomb. I don't remember why they canceled the program, but it was not due to the bird's skills.

Birds rely heavily on their eyesight to find or distinguish food and prey. Thus, they may be as good or better than dogs, who use mostly hearing and smell. Plus, dogs are partly color blind.
