In Southern California, urban developers built over the burrows of the local Western Burrowing Owls, destroying their habitats.
The Burrowing Owl (Athene cunicularia) is a small, long-legged bird in the Strigidae family of owls. It measures 19-28 centimetres (7-11 inches) tall, with a wingspan of 50-61 centimetres (20-24 inches). It is native to North America and South America. It prefers grasslands, rangelands, agricultural areas, deserts and other open dry areas.
Unlike most nocturnal (night) owls, the Burrowing Owl is diurnal, active during the day.
It nests in burrows underground that a prairie dog or a squirrel has dug into the soil. It also nests in other shallow, underground structures.
The San Diego Zoo Wildlife Alliance collaborated with the United States Fish and Wildlife Service to relocate the Burrowing Owls that had lost their homes when humans began building in the area.

The Common Earthworm (Lumbricus terrestris) is a terrestrial (land) invertebrate (without a backbone) in the Lumbricidae family of earthworms. It is also known as the Lob Worm.
The Common Earthworm is pinkish-greyish-purple. The body is cylindrical and a tube-in-a-tube, with a series of segments, called metamerisms. The last segment is the tail, and the first segment has the mouth and prostomium (flat paddle-shaped lobe). Each segment has bristle-like hairs called lateral setae. These hairs help it to move by gripping the surface of the soil. It has pores (holes) in its body that enables it to breathe. It exudes a fluid that keeps the body moist and stops it from drying out.
