Head with four black stripes and three brownish-yellow ones, namely, a black one on each side of the crown and one from behind the eye (extending, in fact, a little anterior to it), a broader median yellow one on the crown, and a superciliary from the bill. Under parts pale brownish-yellow; tinged with buff across the breast and with olivaceous on the sides. Tail unspotted. Female nearly similar. Length, 5.50; wing, 3.00; tail, 2.35. In autumnal specimens the light stripes on the head are deeper buff than in spring. HAB. Eastern Province of United States (rather Southern); Southeastern Mexico; Guatemala; Cuba; Costa Rica; Veragua; Orizaba (winter, SUMICHRAST); Yucatan (LAWRENCE). HABITS. Much remains to be ascertained in regard to the history, habits, and distribution of this interesting species. So far as is now known it is hardly anywhere very common during the breeding-season. Yet its abundance and wide distribution as a migrant during the winter months in various extended localities appear to warrant the belief that it must be correspondingly abundant in summer in localities that have escaped our attention. It has been occasionally met with in the Central and Southern States, as far west as Eastern Mexico, and as far to the north as Southeastern New York. Specimens have been procured from Cuba, Mexico, Central America, and the northern portions of South America. It is a regular winter visitant of Jamaica, whither it goes in the autumn in considerable numbers, and is very widely diffused.
