Hummingbird Attraction to Red Flowers, Fast Pollination, & Resting periods

The hummingbird population observed in the Pasadena City College Science Village seemed to be most attracted to red flowers, such as the Baja Fairy Duster, however they also were observed pollinating the Yellow Trumpet Flower. The hummingbirds seemed to be able to pollinate flowers that bees couldn't, such as the Baja Fairy Duster, maybe because of their long beaks. They are able to pollinate a lot quicker than bees, spending 2-3 seconds on one flower alone. They also took a lot more resting periods than bees. About half of my observations of hummingbirds were of them resting on a branch. This leads to questions about why they are resting. They may compensate for this lost time through their fast pollination, but the amount of energy that they use is greater than bees, thus they need more resting time. This leads to questions as to who is a more efficient pollinator.
