Below are two interesting articles on the relationship between Rufous and Allen's Hummingbirds.The first describes differences in rectrices, the second deals with the zone of hybridization between the two species in N. California and S.Oregon. Thank you to everyone who made it possible for us to see and appreciate the bird. Danny Danforth
