Weeding in my garden this weekend, I saw a tiny flash of green and red speed past the brim of my hat. As I looked up, I just caught wind of a miniscule bird darting toward our hanging feeders. And before I could even get my son’s attention to catch sight of this iridescent acrobat, it was gone to the next source of nectar.The glittering tones I noted as the bird turned to leave were a dead giveaway. It was one of the season’s first ruby throated hummingbirds.
