The HoLARCTIC Region, comprising North America and the extratropical mass of land of the Old World, may from an ornithological point of view be characterized by the Colymbi, Alcidae, Gallidae or Alectoropodous Galli, and the Oscines, which have here reached their highest development; while Ratitae, Tinami, Psittaci, and non-Oscine Passeres (with the exception of Tyrannidae extending into North America and Conurus carolinensis) are absent.
4 These are, according to modern nomenclature, Tyrannus carolinensis and (as before mentioned) T.
Of the various other genera allied to Mimus, the best known are the thrashers (genus Harporhynchus) of which six or eight species are found in North America, which are thrush-like and shy in their habits and do not mimic; and the cat-bird (Galeoscoptes carolinensis), which in addition to having an attractive song, utters clucks, whistles and mewing sounds.
In North America the Carolina parakeet, Conurus carolinensis, at the beginning of the i 9th century used to range in summer as high as the shores of lakes Erie and Ontario - a latitude equal to the south of France; and even much later it reached, according to trustworthy information, the junction of the Ohio and the Mississippi, though now its limits have been so much curtailed that its occurrence in any but the Gulf States is doubtful.
No parrot has recently inhabited the Palaearctic Region,' and but one (the Conurus carolinensis, just mentioned) probably belongs to the Nearctic; nor are parrots represented by many different forms in either the Ethiopian or the Indian Regions.
Carolinensis, the "chameleon," can change colour to an extraordinary degree.
