BIRDS OF COLORADO.

A queer state of affairs has come to light in regard to the 
occurrence of this species in Colorado, that shows strongly how 
much there is yet to be learned about Colorado ornithology. In 
1895 W. P. Lowe gave in the Auk the first published record of 
this species for Colorado. It was considered a rare specimen and 
extended the known range nearly three hundred miles north¬ 
eastward. Two years ago a specimen was sent to the present 
writer that was taken at Rocky Ford, but was supposed to have 
been introduced there. Now it has become known that they are 
common among the cedars on the higher arid lands back from 
the river and miles away from water. The cowboys that rode 
the range at least sixteen years ago, report that they were more 
plentiful there then than they are now. Lately they have been 
working toward the cultivated lands along the river, and during 
the winter of 1899-1900 they have become, in the vicinity of 
Rocky Ford, more common than the Bob-white. The Scaled 
Partridge should therefore be considered as resident; common 
locally.

A few years ago nearly a thousand of these birds were 
turned loose at Grand Junction. They have thriven wonderfully 
and the country now is full of them. They average two broods 
per year and the market gardeners claim they are a nuisance in 
their vegetable gardens.

At last the present writer has had the good fortune to see 
this bird with his own eyes. A family of old and young were 
seen August 12, 1899, on South Fork in Estes Park, at 9,000 feet 
elevation.

Resident. Further records of this species allow us now to 
include it among tlie breeders. Mr. Otto Derr writes tliat at
