Anna's Hummingbird on the Tuolumne River

Spring is springing on the Tuolumne River! I saw quite a few birds on my recent stroll down the Parkway Trail where the Tuolumne flows into the Great Valley. There was a blooming fruit tree along the trail, and I thought I could see something up in the top, and the zoom lens caught the small hummingbird sitting in the luxurious growth of flower petals. It must be a relief to have flowers blooming after the hard times of winter.

I think it's an Anna's Hummingbird (Calypte anna), based on the shape of the dark feathers across the breast, but I couldn't make out any other identifying marks. I'm open to correction if I am wrong!
