The animal on the cover of High Performance Drupal is the Red-shouldered Hawk (Buteo lineatus). The Red-shouldered Hawk can be found in North America, specifically in eastern North America, the coast of California, and northern Mexico. They live in wooded areas and stay within a confined range within those areas.

Adult male Red-shouldered Hawks are 15 to 23 inches in length and tend to weigh 550 grams. Females, on the other hand, are a bit longer than males by just a few inches, and weigh 700 grams. The wingspan of the adult Red-shouldered Hawk ranges from 35 to 50 inches. They have brown heads, red chests, red bars along their bellies, and white bars along their tails. Like many hawks, they have great vision and will swoop down on their prey. They eat rodents, squirrels, rabbits, amphibians, small birds, and large insects.

The Red-shouldered Hawk is a monogamous bird. A breeding pair will typically build a stick nest and will use the same nest every year. The female Red-shouldered Hawk typically gives birth to three to four eggs and after being born the young are dependent on their parents for up to 19 weeks.
