Birch has a habit of always glancing towards the sky, and standing still when he sees something flying. Whether it's a bird, plane, feather, or spiraling leaf, Birch will pause to watch it. He loves to run and climb mountains, and has even managed to get himself stuck in a few trees. He doesn't mind getting his fur dirty, and loves to dig. Combined with his high energy, these traits make Birch into quite the escape artist, and it is hard to secure an enclosure to keep him in for very long.
