Sharp-shinned Hawk - Distribution

Distribution

This species is widespread in North America, Central America, South America and the Greater Antilles. Below the distributions of the four groups (see taxonomy) are described as they roughly occur from north to south:

  • The nominate (A. s. striatus) group is widespread in North America, occurring throughout a large part of USA and Canada, except in the ice-covered regions of the far north. Populations in the northern part of the range migrate south and spend the non-breeding season (winter) in southern USA, Mexico and Central America as far south as Panama, with a smaller number spending the winter in the Greater Antilles. Resident populations exists in temperate parts of USA, Canada (in a few coastal regions), Mexico (highlands from Sonora to Oaxaca), Cuba, Hispaniola and Puerto Rico.
  • A. (s.) chionogaster (White-breasted Hawk) occurs in highlands from far southern Mexico (Chiapas and Oaxaca), through Honduras, Guatemala and El Salvador, to Nicaragua. It is, as far as known, resident, but some local movements may occur.
  • A. (s.) ventralis (Plain-breasted Hawk) occurs in the coastal mountains of northern Venezuela and Colombia, south through the Andes from western Venezuela, through Colombia, Ecuador and Peru, to central Bolivia. A disjunct population occurs in the Tepuis of southern Venezuela (likely to extend into adjacent parts of Roraima in far northern Brazil, but this remains unconfirmed). It is, as far as known, resident, but some local movements may occur.
  • A. (s.) erythronemius (Rufous-thighed Hawk) is widespread in eastern South America in eastern and southern Brazil, Uruguay, Paraguay, north-eastern Argentina and south-eastern Bolivia. It is, as far as known, resident in some regions and migratory in others. The movements are generally poorly understood, but it only occurs seasonally at some localities in Argentina.

Famous quotes containing the word distribution:

    “The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
    —Rutherford Birchard Hayes (1822–1893)

    “Classical and romantic: private language of a family quarrel, a dead dispute over the distribution of emphasis between man and nature.”
    —Cyril Connolly (1903–1974)

    “In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.”
    —Ralph Waldo Emerson (1803–1882)
