 with large laterally compressed claws, inner toe reaching only to 

 second joint of middle toe, hallux equal to outer toe. Wings long 

 and pointed. 1st primary very small, less than one-third of 2nd, 

 3rd and 4th or 3rd, 4th and 5th primaries longest, 2nd equal to or 

 slightly longer than 7th (except Neositta). Tail short, soft, straight, 

 twelve rectrices, broad with rounded tip. Nests in holes of trees 

 or crevices of rocks, eggs white with rufous spots (except Neositta).
