Rufous Hummingbird. The feistiest hummingbird in North America. The brilliant orange male and the green-and-orange female Rufous Hummingbird are relentless attackers at flowers and feeders, going after (if not always defeating) even the large hummingbirds of the Southwest, which can be double their weight. Rufous Hummingbirds are wide-ranging, and breed farther north than any other hummingbird.

I find hummingbirds so fascinating! I've only seen them a few times! I'd love to get a hummingbird feeder to watch them all of the time!
