 The Advisory Council

N a former occasion we have commented on the happy results which have followed BIRD-Lou's el‘iorts [0 bring the isolated student in touch with an authority on the bird-life of the region in which he

lived, through the formation of an Advisory Council composed of prominent ornithologists representing the United States. Canada. 'Mexico and the West Indies. The plan has worked admirably, and we are assured that the many of our readers who have established pleasant relations with members of the Council will be glad to know that, beginning with the present num- her. we propose to publish. in BIRD-LORE, the portraits of the ornitholo- gists composing the Council. The full list of Councilors will appear in the next issue of BIRD»LORE.
