Another interesting species is the toucan (Ramphastos), whose enormous beak, awkward flight and raucous voice make it a conspicuous object in the great forests of northern Brazil.
In strong contrast to the ungainly toucan is the tiny humming-bird, whose beautiful plumage, swiftness of flight and power of wing are sources of constant wonder and admiration.
Owen's description showed this view to be groundless, and he attributed the extraordinary development of the toucan's beak to the need of compensating, by the additional power of mastication thus given, for the absence of any of the grinding structures that are so characteristic of the intestinal tract of vegetable-eating birds - its digestive organs possessing a general simplicity of formation.
Among the Amazon species may be mentioned the parrot, macaw (Macrocercus), toucan (Ramphastos), curassow (Crax), penelope, trogon, and horned screamer (Palamedea cornuta).
The pedestrian subway at Hereford Street will be replaced with a new on-street toucan crossing for pedestrians and cyclists.
