Lucy and Vivian are two of my dark green linnies. They were not always friends; it took a few months for them to develop a positive relationship. They love to play on my old sweater. When I put it on, I become their jungle gym. I am holding my EasyShare camera with one hand to take this video so it is not as clear as I'd like. Still it shows why so many people find linnies so loveable. With their big eyes and sweet voices, they are like the Star Trek tribbles with feathers.
