In this beautiful little species we have another instance of 

 the mistakes occasioned by the change of colour to which 

 many of our birds are subject. In the present case, this 

 change is both progressive and periodical. The young 

 birds of the first season are of a brown olive above, which 

 continues until the month of February and March ; about 

 which time it gradually changes into a fine slate colour, as 

 in the figure on the plate. About the middle of April this 

 change is completed. I have shot them in all their grada- 

 tions of change. While in their brown olive dress, the 

 yellow on the sides of the breast and crown is scarcely 

 observable, unless the feathers be parted with the hand ; but

 cheek are then also obscured. The difference of appearance, 

 however, is so great, that we need scarcely wonder that
