Type of animal science: Classification Fields of study: Anatomy, ornithology, systematics (taxonomy) The finches are some of the most widespread and successful of all songbirds. Of relatively recent origin
and uncertain taxonomic status, they are united in possessing several basic characteristics: All are small, seed-eating
songbirds that have a bill adapted for gathering, holding, and, in some cases, crushing seeds.
Type of animal science: Anatomy, classification Fields of study: Anatomy, ornithology, zoology Eight flamingo types exist, all beautiful red, pink, or white water birds. Hunted to near extinction in the United
States, they inhabit Europe, Africa, Asia, South America, and the West Indies. A great threat to flamingos everywhere
is pollution and destruction of their habitats

Type of animal science: Anatomy, classification, reproduction Fields of study: Anatomy, entomology Flies are members of the order Diptera, two-winged insects, of which there are 95,000 species. Flies are related to the
other dipterans, the mosquitoes.

(taxonomy), wildlife ecology, zoology There are approximately twenty-one species of fox, in the order Carnivora. Foxes constitute only 0.5 percent of the
four thousand mammalian species, but play a very important role in the environment.
Type of animal science: Anatomy, classification Fields of study: Anatomy, conservation biology, herpetology, systematics (taxonomy) The more than four thousand living species of frogs and toads are classified in the order Anura. Most species have a
biphasic life cycle, in which a larval stage, the tadpole, develops in water (or land, in some species) and undergoes an
abrupt metamorphosis into the adult body form.
