Some invasive species are definitely best kept indoors. Take, for example, the Quaker parakeet (monk parrot, Myiopsitta monachus) featured in this Yahoo! News story. The adorable bird, named Willie, recently saved the life of a little girl by screaming "Mama! Baby!" until the babysitter came into the room and realized that the girl was choking. Luckily girl and parrot are both okay. Something tells me Willie got an extra treat that day, and some scratchies, too :-). If this story isn't already sweet enough for you, check out Cute Overload!'s version of the story, which comes with extra shots of cute Quakers.
