On 30 November 1991 my wife, Martha, and I received a call from Mary LeGault of Mobile notifying us of a very small hummingbird coming to her feeder. After questioning her in detail on the telephone, we were convinced the bird was in the Se/asphorus genus. In the United States this would include the Rufous (S. rufus), Allen’s (S. sasin) and Broad-tailed (S. platycerus). Although Mrs. LeGault’s experience with hummingbirds was limited to the Ruby-throated (Archilocus colubris), her description of the bird warranted immediate investigation. A complicating factor was her description of a second hummingbird at the same feeder, another Selasphorus with considerable brown in the back, indicating an immature male Rufous.
