This bird is very easily made to breed in confinement. Dr. Bachman has had a single pair thus raise three broods in a season. The eggs of this species measure .8(1 by .65 of an inch, and do not at all resemble tht* eggs of the cyanca or amana. They have a dull or pearly- white ground, and are very characteristically marked with blotches and dots of purplish and reddish brown. Genus SPERMOPHILA, Swaixson. Spcrmnjihihi, Swainsox, Zoiil.
