To the few records of this bird in Colorado Mr. Carter now 
adds two more. One was taken in Middle Park May 20, 1884, 
at 7,000 feet, and one taken in South Park May 21, 1876, at 
about 8,000 feet. These are farther west and at a higher altitude 
than any previous Colorado records. Mr. C. E. Aiken saw a 
female at Limon in May, 1899.

All three of these Blackbirds have been found by Mr. Carter 
breeding in Middle and South Parks, and all have been taken at 
Breckenridge, but only in migration.

Seen by Mr. Carter in Middle Park, but contrary to what 
would be expected, he has never seen it at Breckenridge.

The record is now complete for Colorado for every month in 
the year. They had been seen in the State from the first week 
in August until late in May. On June 19, 1898, Mr. C. E. Aiken 
found a flock of twenty-five to thirty birds in the foothills near 
Colorado Springs. He killed five males. The testicles of each 
were the size of a bean, and it was evident that the birds were 
breeding in the mountains and had come down to feed on the 
insect larvae that were ravaging the young oak leaves. The year 
is completed by the record of Mr. L. A. Test of the Agricultural 
College at Fort Collins, who on July 22, 1899, and again the 
next day, in Estes Park, saw a party of eight, apparently three 
old birds and five young ones. Mr. P. L. Jones of Beulah reports 
that during May and June, 1898, these birds were constantly 
around his premises. Late in June he saw a flock of seventeen,
