The importance of vision in the hovering hummingbirds was investigated in the following study:

PMID 25489117

HUMMINGBIRD FLIGHT MUSCLES

This research discovered that hummingbird flight muscles contain exclusively fast muscle fibers (Fast Oxidative Glycolytic [FOG]), which is not typical of birds in general:

My experience fifty years later was not too different from what is described in the piece.

HUMMINGBIRD ATTACKS

These researchers compared the performance of Ruby-throated Hummingbirds who were defending, being chased from, and freely departing from a feeder. In addition to finding that the birds maxed out their speed and acceleration during feeder conflicts, they also found that the defending birds aimed toward the encroaching bird rather than the feeder.

TAIL-USE IN HUMMINGBIRDS
