Catalog # 1449 was labeled as a Yellow-bellied Sapsucker (Sphyrapicus varius). However, this adult male had the field marks of a Red-naped Sapsucker (Sphyrapicus nuchalis). While these two species can be problematic in the field, adult males in the hand can normally be easily identified. This specimen was collected in Coahuila, Mexico in 1940.
