This Warbler is an irregular migrant in the greater part of its range; sometimes it will not be seen at all in a locality where in previous seasons it was fairly constant. The chest- nut colouring of the breast is the distinctive mark by which it may be recognized, and this dull red breast renders it conspicuous and more likely to be discovered than many plainer, though more common species. In full spring plu- mage the male looks, at a little distance, like a well-fed Robin in miniature.

The Bay—breasts seem, according to many authorities, to be very freaky and capricious as to the course of their migrations, and it is said they return to the South by a dif- ferent route from that by which they travelled up in spring, no two people being able to agree with certainty as to the locations where they may be found. Dr. Allen, in his “List of Massachusetts Birds,” says that they are common in both migrations, varying in abundance; While Mr. Minot says that as a rule these birds are rare in spring in eastern Massachusetts and are never seen in autumn,—the con- sensus of opinion being that in some seasons the birds take a westerly course in spring and an easterly in autumn, or vice versa. All of which goes to prove that you may have considered this Warbler an unknown bird in your locality, and some May morning in looking out your window you will find a little party of them almost peering in at you.
