I hope hummingbirds read Wikipedia – because according to the information there, this must be a Allen’s Hummingbird (Selasphorus sasin). Wikipedia also says that the females are extremely difficult to differentiate from Rufous Hummingbirds (Selasphorus rufous) – except for the range!
Since we’re here in San Diego, and a chick/fledgling would indicate “breeding”, this must be an Allen’s, since the Rufous is here only as a migratory visitor. Simple, eh? I just hope they respect their range, as defined in Wikipedia. 😉
This was also a first in our backyard. We’re seeing plenty of Anna’s Hummingbirds (Calypte anne) buzzing around here, and had a nest in one of our lemon trees a few years ago. In a pine tree, we also had a nest of Black-chinned Hummingbirds (Archilochus alexandri).
But we haven’t had any Allen’s Hummingbirds here, and seeing one with a fledgling was a treat. The little one must have left the nest not too long ago. It started buzzing its wings, a little bit like a sputtering outboard motor, made it onto a small twig and rested there, waiting for mother to arrive with more “fuel”, apparently.
They didn’t mind our presence too much while this was going on and I was able to grab the camera, mount Big Bertha (the 200-500mm lens), and make a few photos, of which the one below turned out best.
With the help of Topaz’s Sharpen AI (indistinguishable from magic for me), I added some sharpness to the female, as it was slightly outside of the range of acceptable sharpness at 500mm and f/5.6 (this was at ISO 3200 already as the two birds were in the shade of some bushes in the morning).
