Description

All are large-bodied with robust legs and feet, and formidable shrike-like bills. As in other Malacotini, the upper mandible (maxilla) has a subterminal tooth, opposing a notch on the lower mandible. Both nasal and rictal bristles are present, and they are unique in their family in having syndactyl feet (3rd and 4th digits fused). They have 10 primaries and 12 rectrices like others of their family. The sexes are similar in appearance, but have dissimilar calls.


Habits
