Habits, $c. A shy restless bird, keeping to high forest, usually 

 in parties of 8 or 10, and flying with the almost noiseless flight of 

 Anthracoceros, alternately flapping and sailing. The nest has been 

 described by Major Bingham, who found from 3 to 5 eggs in each 

 of the usual nest-holes in February. The eggs are white originally, 

 but generally stained during incubation, and average 1'82 by 1*34 

 in dimensions. These birds, according to Major Bingham, are far 

 less wary in the breeding-season than at other times.
