I love hummingbirds. Interestingly, even though it is relative easy to invite them to your yard with feeders, just about all of the photos I have are from wildlife areas, such as Delta Ponds. I knew just the trees where I would see them anytime I went there. It is great fun to capture them in wildlife areas like that. This one was at the top of a small tree.
Some good information about hummingbirds and the Anna's family is the Cornell Lab's All About Birds - https://www.allaboutbirds.org/guide/Annas_Hummingbird/id
