Western Grasshopper Sparrow. 
A large series of this Sparrow submitted to Prof. Allen and 
Mr. Ridgway are all considered as true perpallidus.

Sparrow. 
One taken by Mr. H. W. Nash at Pueblo, October 18, 1893. 
This is the third record for Colorado.

The more the Chipping Sparrows of Colorado are investi¬ 
gated the more evident it becomes that the eastern form is far 
less common in the State than had formerly been supposed. 
There is need of - much more work in the matter on the plains 
of eastern Colorado, before the distribution of the two varieties 
can be determined.

In the fifth line the “5th of October” was a misprint in the 
original article for the “5th of November.” Mr. Aiken writes 
that the earliest he has seen the birds at Colorado Springs is 
October 26, 1897.

At Magnolia, Boulder County, at 7,500 feet, Mr. W. A. 
Sprague found eggs May 25, 1896, and young birds a week old 
May 29, 1897. On July 6, 1897, he also found young birds 
newly hatched showing that two broods are reared in northern 
Colorado. Mr. Aiken thinks that these Juncos winter in the 
mountains as far'north as Colorado Springs, coming to the 
plains during storms and returning to the mountains as soon as 
the weather moderates.

row. 
The known northeastern extension of this species has been 
largely increased by a specimen taken just over the Colorado 
line in Wyoming, near Cheyenne, by Mr. F. Bond. The speci¬ 
men is now mounted in his collection. This is apparently the 
first record east of the Front Range.

row. 
Summer visitant; rare or accidental. Only one instance 
known, seen by Mr. x\iken, at Colorado Springs, the latter part 
of August, 1897. Regularly comes west only to the plains, but 
has been once taken in Utah.
