The Louisiana Ornithological Society (LOS) was organized in 1947 to gather and disseminate accurate information concerning the bird life of the western hemisphere and of Louisiana; to promote interest in and appreciation of the value of birds, both aesthetic and economic, which will ensure wiser conservation of our bird life; to promote opportunity for acquaintance and fellowship among those interested in nature; and to issue, at such times as possible or practicable, publications as a means of furthering these ends.

The spring passage begins the second week of March and extends into May, rarely to the end of that month. On the bird's return southward it occurs here from the end of August to the first part of November, rarely later. The only winter record is of one seen on the Venice Christmas Bird Count on January 3, 1965, and carefully studied by four persons. The male Blackburnian Warbler in nuptial plumage is black and white with flaming orange on the head and throat. The female is not so brilliant but is still easily recognized. In fall the adults and immatures alike lack the orange on the head and throat, but the basic pattern is there – yellow throat, dark ear patch, black and white stripes on the back, and white wing bars. The song has been described as a chiddle chiddle chiddle chick-a chick-a cheet. The species breeds in the evergreen forests of Eastern Canada and the northern fringe of the United States, as well as the Alleghenies as far south as northern Georgia. It winters in Central America and northern South America. --George H.
