Bulletin No. 56, being a technical bulletin, is printed in a small edition and 
is not sent to the general mailing list. It will be sent to individuals upon request. 
The bulletin is a second appendix to No. 37 on “The Birds of Colorado,” 
by Professor W. W. Cooke, of which No. 44 was the first appendix. It gives lists 
of birds that have been found in Colorado, with localities where they have been 
found, and some notes. 
Some who receive this bulletin may have a copy of No. 37 which they do 
not need, or are willing to spare for the benefit of others who have greater use 
for it. Requests come from many who have good reason to desire a copy, which 
the Station cannot supply. Send to the Station or address
