It's that time of year again, when the hummingbirds are moving through northern Utah in concentrated numbers, giving us great opportunities to study, watch, photograph, and take video of them as they visit feeders on their treks south. In the past week I have had all 4 of Utah's regular fall migrants in my yard, and today spent some time watching the Broad-taileds as they fought over the sugar water with the Black-chinnned. This video was the best I was able to capture.
