Especially solicited are records of uncommon species, nesting birds, and early, late, or out-of-season/range birds. Records should be submitted in taxonomic order and should include species name, date, exact location, numbers of birds, age, sex, and color morph (if applicable), and name and contact information of observer. Details are necessary for unusual records; these may be submitted on a report form (available from the address above), but any written format is acceptable. Photographic documentation is strongly encouraged. NEW MEXICO ORNITHOLOGICAL SOCIETY (Founded 1962) The New Mexico Ornithological Society was organized to gather and disseminate accurate information concerning the bird life of New Mexico; to promote interest in and appreciation of the value of birds, both aesthetic and economic, to further effective conservation of the state’s avifauna; to facilitate opportunity for acquaintance and fellowship among those interested in birds and nature; and to issue publications as a means of furthering these ends. Membership and Subscriptions: Membership in the New Mexico Ornithological Society is open to anyone with an interest in birds. Memberships are for a calendar year and annual dues are payable 1 January. Dues are: Regular Membership $10; Family $15; Student $5; Supporting $35; Life $300. Address for the New Mexico Ornithological Society: P. O. Box 3068, Albuquerque, NM 87190-3068. Cover: Neotropic Cormorant (Phalacrocorax brasilianus). Known from New Mexico since the 1850s, this waterbird reaches its northernmost limit in New Mexico, where it is a rare breeder in the middle Rio Grande Valley, and where it is threatened by loss of breeding sites, disturbance, food supply fluctuations, and persecution.

SPRING SEASON 2003 Although some precipitation materialized in March, Spring 2003 saw continued drought conditions over most of New Mexico. Migration was judged “slow,” but persistent birding discovered several surprises, including at least one species potentially new to the state. Concentrated efforts along the Canadian River in eastern San Miguel County and the lower Mimbres River in northwestern Luna County provided numerous distributional records, as did continued work in Colfax and Hidalgo counties.
