AGELAINiE. 
It is in marshy places, on the borders of the great rivers of South America, that these birds are generally seen, 
perched on the low trees or reeds, and sometimes on the ground. The nest is suspended among the reeds at a short 
distance from the ground, and is made entirely of stalks of grass. The female deposits three or four eggs.

Amblykhamphus Leach * 
Bill as long as the head, with the culmen straight, broad, and much flattened above from the base 
("where it advances on the forehead) to the tip, which is rounded ; the lateral margins straight, but 
an gulated at the base ; the gonys lengthened, straight, and advancing upwards to the end ; the nostrils 
basal, lateral, and partly concealed both by a membrane and projecting plumes. Wings moderate, with 
the first quill shorter than the second, and the second rather shorter than the third, fourth, and fifth, 
w hich are the longest. Tail moderate and rounded. Tarsi the length of the middle toe. Toes 
haigthcned with the lateral ones unequal, and the hind toe nearly as long as the tarsus ; all armed with 
^° n S and slightly curved claws. 
This species frequents marshy places in flocks. It is more solitary than those of the other genera of the family. 
“ Seated,” says Mr. Darwin, “ on a twig, with its beak widely open, it often makes a shrill, but plaintive and agreeable 
k'j which is sometimes single and sometimes reiterated. Its flight is heavy.’
