Nice hummer, I have 2 that hang around our camper every 12 minutes I’ll have to work at getting one. They aren’t the easiest
I have much better success with the females as the tend to behave differently. The females are far more likely to hover in one spot, move in to feed, and then return to hovering in the same spot.
The males are far more inclined to dive in, eat, and leave. But they often will perch nearby to keep an eye on things.
I just returned from friends in MD and spent a lot of time photographing "their" hummingbirds. There were two males who were far more interested in protecting territory than eating, the boneheads would even chase the females away!
I also will typically shoot in Aperture Priority to help get a little more depth of focus and adjust the ISO to get a shutter speed I want. But don't get too hung up on super-high shutter speeds, I've gotten good shots at 1/800 sec and even a little lower.
