acute. Feet slender; tarsus naked, much longer than the 
longest toe ; nails short, but little incurved. Wings short, 
rounded ; spurious feather short; third, fourth and fifth pri- 
maries longest. Tail moderate or elongated, rounded or

Inhabit the warmest parts of both continents : none in 
Europe : two in North America during summer. Replace

especially in habits. Build a nest in hollow trees, and breed 
up their young ; reside in dense forests ; seldom alight on the 
ground; feed on insects and berries.
