cormorants.
Dogs might be man's best friend, but they're also our most reliable coworkers -- for thousands of years, we've put them to task guarding homes, hauling sleds, trailing game, herding sheep, and even finding lost pets. Now we're taking some of the pressure off helpful pups by letting other members of the Animal Kingdom help out. From bees and birds to rats and pigs, we're putting all kinds of critters to work. We just hope they get decent vacation time. http://xml.channel.aol.com/xmlpublisher/fetch.v2.xml?option=expand_relative_urls&dataUrlNodes=uiConfig,feedConfig,localizationConfig,entry&id=709125&pid=709124&uts=1251904321 ...
