Nestling. Irides hazel ; bill, legs and toes very pale

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 ])riraaries 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 

 14tli of December, 1908, when both young and eggs were 

 found in the same nest. They measure : axis 1*1 to 1T6 in., 

 diam. 0*8 to 0-83.
