The BENTEVI (_Saurophagus sulphuratus_), a well-known species, resident in Brazil, is recognisable by its comparatively long wings and slightly incised tail. Its legs are powerful, tarsi high, toes long, and armed with sickle-shaped claws; the beak, which is higher than it is broad, and terminates in a hook, is of a conical shape, and equals the head in length; its culmen is slightly rounded, and its base surrounded with bristles. These latter are particularly numerous in the region of the cheek-stripes. The length of this species is five and its breadth ten inches; the tail measures three inches. Upon the upper part of the body the plumage is of a greenish brown; the forehead and eyebrows white; the crest-like feathers upon the crown of the head are of a brimstone-yellow; the sides of the head, the bridles, and cheeks black; the wing-covers, tail-feathers, and quills are broadly edged with rust-red; the throat and fore part of the neck are white; the breast, belly, rump, and legs sulphur-yellow. In the plumage of the young the top of the head is entirely black; the wing and tail-feathers are broadly edged with rust-red; and all the colours paler than in those of the adult birds. The Bentevis are extensively met with throughout South America, particularly in well-wooded pasture-land or meadows; indeed, their loud, penetrating voices may literally be heard from every tree. We learn from Schomburghk that though they subsist principally upon insects, they also devour the nestlings of other species, and frequently visit the houses of the inhabitants in order to pilfer scraps of the meat hung out to dry. So bold are they that it is not uncommon to see them picking up their insect prey from under the very feet of the herds of cattle as they graze. Towards their feathered companions they exhibit unceasing animosity, chasing them and harrying them from spot to spot with loud spiteful cries, occasionally venturing to carry their pugnacious propensities so far as to attack some of the larger birds of prey. As the breeding season approaches, they become still more quarrelsome and noisy, until the air resounds with the voices of both the males and females as they chase each other in angry rivalry or sport among the branches, or so constantly utter their strange cry as to appear prompted by an anxious desire to outdo their companions, both in loudness and rapidity of utterance. This cry, from which the name of the species is derived, has been freely interpreted by the inhabitants of Monte Video and Buenos Ayres to mean, "_Bien-te-veo_," "I see you well," and in Guiana into, "_Qu'est ce que dit?_" [Illustration: THE TRUE TYRANT SHRIKE, KING BIRD, OR TYRANT FLY-CATCHER (_Tyrannus intrepidus_).]
