Y ELLOW-THROAT. 
One was seen May 8, 1898, by Mr. L. B. Gilmore at Sweet¬ 
water Lake at 8,000 feet. 
Mr. Carter has found it breeding at Dillon at 9,000 feet.

Warbler. 
Its occurrence in Colorado will now be changed to: Summer 
resident; not uncommon. 
There is in the Carter collection a specimen, quite typical, 
that was taken with nest and eggs at the eastern side of South 
Park, July 3, 1878. Mr. C. E. Aiken believes that this form is 
fully as common in Colorado as the eastern pusilla.

Warbler. 
Migratory; rare or accidental. Added to the Colorado list 
by Mr. C. E. Aiken in the following note: 
“The range of this species is extended westward nearly to 
the Rocky Mountain range by my capture of a male at Lake, 
Lincoln county, May 23,1899.

Breeds in Middle Park. The foregoing records show that of 
the twenty-nine Warblers known to occur in Colorado, but three 
have been taken breeding at Breckenridge by Mr. Carter, show¬ 
ing how few of these birds go up into the high mountains. 
There are twenty-five Warblers given in the last edition of 
the A. O. U. Check List whose range is said to be “Eastern 
United States” or “Eastern United States to the Plains,” thus not 
including Colorado in their habitat. These have all been taken 
in Kansas, and eleven of them have been found in Colorado. 
Since these eleven include several that would have been con¬ 
sidered as little hkely as any to be found in this State, we may 
expect that sooner or later most of the other fourteen will be 
noted in Colorado. Those not yet found here are Protonotaria 
citrea, Helmitherus vermivorus, Helminthophila pinus , llelmin- 
thophila ruficapilla, Dendroica pensylvanica, Dendroica blackburnise, 
Dendroica dominica albilora, Dendroica virens , Dendroica vigorsii, 
Dendroica discolor , Seiurus motacilla, Geothlypis formosa , Geoth- 
lypis Philadelphia, and Wilsonia mitrata.
