Distribution.—Eastern North America, breeding from Pennsylvania to

The only record of the occurrence of this eastern bird in Colorado 
is that of Anthony, who wrote to Cooke that he had shot a female 
example near Denver, November 15th, 1885; it was in company 
with Cassin’s and the House-Finch, and can only be considered a 
straggler in the State.
