Cormorant. 
In the summer of 1897, the Cormorant was found breeding 
by Prof. Knight, near Buffalo, Wyo. This is quite a long dis¬ 
tance north of Colorado, but yet it increases the probability of 
the bird’s occurring as a breeder in this State.

A third specimen can now be recorded. According to Mr. 
H. G. Smith one, was purchased by a local taxidermist in the 
Denver market December 12, 1894. It is presumed that the 
bird was shot in Colorado.

One was taken by W. G. Smith at Loveland sometime 
previous to 1892. Prof. Wm. Osburn writes that he saw the 
specimen in Mr. Smith’s collection. 
There is a mounted bird of this species at the rooms of the 
Society of Natural History in Denver. There is no record 
accompanying it, but it was presumably taken in Colorado 
nearly twenty years ago.

During the summer of 1897, this species was noted by the 
present writer as nesting five miles west of NiWot at about 
5,500 feet. This is several thousand feet lower than previous 
records.

In the third line, the word “Texas” should be New Mex¬ 
ico, the reference being to the record of Dr. Cones at Albuquer¬ 
que. The birds reported by Mr. Beymer in the Rocky Ford 
Republican and by the present writer on his authority in the Auk 
were really the White-faced Glossy Ibis {^Plegaciis guarauiia).

Summer resident; rare. The number of known occurences 
is now double what is was a year ago. As stated above the 
birds seen at Rocky Ford were really this species instead of the 
Scarlet Ibis. A flock of six were seen there on the Arkansas
