A couple of mornings at Madera Canyon, the Blue-throated Mountain Gem made an appearance. It was a female, so no blue throat, but she’s still a real big gem in her own right. The Blue-throated Mountain Gem is the largest hummingbird in the US, larger than the Rivoli’s. In past years I’ve photographed the gorgeous, blue-throated male but this year, it was just a female, perched on a twig while she waited her turn at the feeders.
