OAT-BIRD. 
other insects. Its flight is low, often rapid, and somewhat protracted, gene- 
rally performed by glidings, accompanied with sudden jerks of the tail. It 
moves on the ground with alertness and grace, not unfrequently going before 
a person the whole length of the garden-walk. 
The nest of the Cat-bird is large, composed externally of dry twigs and 
briars, mixed with withered leaves, weeds, and grass, and lined with black 
fibrous roots, neatly arranged in a circular form. The eggs are from four 
to six, of a plain glossy greenish-blue, without spots. Two and sometimes 
three broods are raised in the season. 
I have placed a pair of these birds on a branch of the blackberry bush, 
on the fruit of which they feed. The young attain their full plumage before 
they depart in autumn.
