Annumbius D'Orb.* 



Bill long, slender, and the sides compressed, with the culmen slightly arched to the tip, which is acute ; 

 the nostrils basal, lateral, with the opening small and partly closed by a membrane. Wings moderate, 

 with the first quill shorter than the second, third, and fourth, which are the longest. Tail long and 

 broad, with the end of each feather obliquely pointed. Tarsi as long as the middle toe, and covered 

 with the scales. Toes long and slender, with the outer toe longer than the inner ; the hind toe very 

 long and robust; the claws long, compressed, curved, and acute. 



The species of this genus are found in pairs in the forests, and on the borders of thickets, or even close to the 

 habitations of man, in the warmer parts of South America. When perched, their posture is threatening and animated, 

 especially that of the male when delivering his sonorous notes. They fly with a jerking motion from bush to bush, 

 perching on the highest point. They are sometimes noticed walking on the ground with a slow pace, searching for 

 the small insects, worms, and snails, on which they subsist. Each pair is usually perched close to its enormous nest, 

 which they do not quit except to seek food, and then they return immediately to defend it against the approach of 

 other birds, which they attack without reserve, and without fear of their size. The nest, on which they are constantly 

 working is placed, often much exposed, at the end of the inclined branches of a spinous tree, or in the middle of an 

 isolated bush. It is sometimes constructed over streams, and not unfrequently two are placed together ; and it is 

 extraordinarily large for the size of its constructors, reaching sometimes two feet in height, and one and a half in 

 diameter, of an elongated oval form, with the broadest part below. Its outside is protected by many large thorny 

 branches, intertwined with such art that they cannot be pulled asunder without destroying the interior of the nest, 

 which is lined with feathers, hairs, and straw. Internally it consists of two chambers, of which one is rather spacious, 

 and opens on the side or top. In this chamber there is a corridor, which at first ascends, and then leads down to a second 

 compartment better furnished with feathers, &c, and on these the female lays four or five eggs. The parents, who 

 take great care of their nest, drive their young from it as soon as they are old enough to take care of themselves. 



Established by M. D'Orbigny and Baron Lafresnaye in 1838 {Synopsis Avium.).
