Nestling. Irides hazel; bill, legs and toes very pale 
fleshy. 
The March and April birds are moulting. The August 
and September birds are much worn. The young bird differs 
from the adult only in having the blue of the wings slightly 
less bright, the primaries and secondaries being more 
distinctly tipped, and the grey forehead being washed with 
greenish. 
The northern birds appear rather smaller than the southern 
specimens, and I at first thought them distinct, but there 
is some individual variation, and in measurements they 
intergrade. 
So many excellent notes have been written on the habits 
of this common Parrot that I can add nothing. 
Seven eggs are in this collection, taken at Ajo on the 
14th of December, 1908, when both young and eggs were 
found in the same nest. They measure : axis IT to 1T6 in., 
diam. 0’8 to 0*83.
