Dear Aldo: 
Stoddard wrote me where to find the data on (iail 
weights from birds of known ages: that is, selected as 
to young,(birds of the year) and as to birds older than 
1 season. These figures were taken from the Chubb 
Plantation in February, 1928, by Sid Stringer, birds 
being classified by the primary method, The sharp outer 
primary indicates a young bird; utde, blunt feather 
indicates an older bird. 
 
Sixty nime birds of the year and thirty two older 
birds were weighed* All sexes were figured together.

I have checked over the above figures and can certify they are 
copied correctly from the records.  I hope they will be what you 
want and will enable you to check up on your weight hypothesis. 
 
Sincerely, 
Cooperative Agent
