This afternoon, I watched a hummingbird that I *think* is a Broad-tailed dive at Lesser Goldfinches. In flight, the hummingbird flashed its tail, which included noticeable orange coloring. The hummingbird was definitely not an adult male. It lacked the gorget and didn't make the trilling call during its dives. It's throat seemed spotted. The light's a little tough for clean views with my binoculars, whose lenses aren't clean enough for a clean view of a tiny bird in tough light. I lost the bird during a trip inside to nab my camera.
So if I have the identification to species correct: is this a first-year male? Have they already left nests (I suspect not, at least around here)? Or do the females also dive at other birds? (I'm not seeing a reference to females Broad-tailed Hummingbirds diving in *Birds of the World*.)
I'll work on getting a better view...or better yet, a photo.
