The animal on the cover of Designing for Performance is a tufted coquette (Lophornis ornatus), a tiny hummingbird that breeds in eastern Venezuela, Trinidad, Guiana, and northern Brazil.
Also known as the splendid coquette, this hummingbird is so tiny that it can easily be confused with a large bee as it moves from flower to flower. Its red beak has a black tip and is short and straight. The female doesn’t have very flashy plumage, but the male has striking black-spotted and orange-colored feathers that project from the sides of his neck and an orange head crest.
Hummingbirds in general are quite solitary, so the tufted coquette is mostly found alone or in small groups, as it searches for nectar and small insects to feed on.
Many of the animals on O’Reilly covers are endangered; all of them are important to the world. To learn more about how you can help, go to animals.oreilly.com.
