Mr. Caley in his Notes seems to consider this bird as the 
young of the last species. It differs much in the ground-colour 
of the upper parts, and in the fascie of the lower; while the 
spots on the tail are ferruginous instead of being white. These 
however are differences which may be easily supposed to take

nearly as much in its early and adult ages. But there is one 
character in which the two birds before us differ, and which is
