Our yard is a wildlife sanctuary. By American standards it's a pretty small yard, but it abounds in nature, especially considering how developed the area is. We lack only a consistent water supply (and the $20 processing fee) to be a National Wildlife Federation Certified Wildlife Habitat. We're working on that; the water source needs to be accessible to wildlife (so the pool doesn't count) without being a breeding ground for mosquitoes.
Lizards and frogs abound, because we dispensed with dangerous pest control services a few months after we moved here over 30 years ago. Snakes are not as plentiful as they once were, because too many people in the neighborhood think the only good snake is a dead snake. :( We have all sorts of birds, from mockingbirds and Carolina wrens to woodpeckers of several varieties to flocks of ibises to hawks, owls, and recently a swallow-tailed kite.
There have been reports of bears in the neighborhood, but actually I'd just as soon they give our yard a pass. It's really too small to accommodate a bear comfortably, and bears have been known to rip down pool screens without a second thought.
The middle-sized animals are more fun. Our current little raccoon is too shy (read: too nocturnal) for me to have caught him on film yet, though I enjoy his company in the darker hours. Here is a pair of friends who allowed me to photograph them this morning.
