Synon. : Leucospizia Kaup. 
With bent cere, and a strikingly high beak abruptly bent. Middle digit 
covered entirely with a shield, rather shorter than the more slender tarsus, as 
far as the latter is covered with a shield. First five primaries indented. When 
young these birds, like the Uraspizae, whose place they occupy amongst the 
Astures, have a large number of narrow bands on the tail, which disappear en- 
tirely with age. The chest also has bands when young.
