Finally everything came together! First thing this morning, I set up my tripod, metered, and waited for hummingbirds to come to the feeder. They visited briefly several times, but I was unable to get a manual focus. Finally a young male Ruby-throat hovered, then perched. He stayed for about a minute, which allowed time to focus manually and take continuous photos. See the small red spot on his throat? Juvenile males develop spots in August and September. During his first molt, he will obtain the iridescent red throat of an adult male.
