Broad-billed Hummingbirds were bullies at the feeders in Madera Canyon. They were the overwhelming majority at the feeders and they harassed and chased any other hummers feeding, Broad-billed as well as the other species there. But the Broad-billed Hummingbirds were no match for the honeybees. They were intimidated by the bees that swarmed on and around some of the feeders in great numbers, completely covering the feeding ports. It was not unusual to see a hummer suddenly back away from a feeder as one or more bees got too close.
