 are longest and equal, the second is rather shorter than the fifth but 

 much longer than the sixth, and the first is about equal in length 

 to the secondary-quills. The tail is square at the tip, the feathers 

 rather wide and about five-sevenths the length of the wing. The 

 tarsus is about one-third longer than the exposed culmen. Colo- 

 ration : male and female similar.
