Caracara is a genus in the family Falconidae and the subfamily Polyborinae. This genus consists of two extant species, the northern and southern crested caracara, and one extinct species, the Guadalupe caracara. The only visible difference between the two living species is that the southern species possesses more barred plumage than the northern species. The minor physical differences between these species resulted in their originally being classified as a single species.

Appearance[edit]

The Crested Caracara is distinguished by its long legs and medium size[1].The birds can reach a length of 19.3-22.8 inches long from head to tail[2]. There are usually four points of identification of the Caracara: strikingly white markings on the neck, the tip of both wings, and the tail[3]. Along with their medium length, the Caracara also has a wingspan that can extend from 48.0 inches to 49.2 inches[4]. When flying, the Caracara is often noted to have a pattern on their underside that looks like a cross[5].

Behavior[edit]

The behaviors of caracaras are considered quite strange in relation to other falcons.[6] The bird is often seen walking on the ground in search of prey, using its long legs to maneuver its landscapes.[7] In addition to a preference of walking over flying, the birds also create close bonds with their mates.[8] These birds will also harass large species of birds in order to take the food they caught.[9] In flight, this bird is known for having very direct flight. It does not soar for leisure.[10]

Taxonomy[edit]

The northern and southern crested caracara are the only living examples of the modern genus Caracara.

Prehistoric extinctions[edit]

Known from fossil records:

  • Bahaman caracara (Caracara creightoni) – Late Pleistocene[12]
  • Terrestrial caracara (Caracara tellustris) –Late Pleistocene [13]
  • Caracara major (Venezuela)- Late Pleistocene[14]
  • †Puerto Rican caracara (Caracara latebrosus) –Late Pleistocene[15]
  • †Seymour's caracara Caracara seymouri (Peru, Ecuador)- Late Pleistocene[16]

Prehistoric records[edit]

The fossil record proves the long history of the mainland "Crested Caracaras". Remains of Northern Caracaras, slightly larger than those of modern times but otherwise identical, were found in the famous La Brea Tar Pits.[17] In addition, the Guadalupe Caracara may derive from an already distinct population of Northern Caracara in western Mexico that, subsequently, was displaced by the main continental population.
