Gleaning Insects

Why is this hummingbird so interested in the tomato when it looks too dry to have any juice left? The hummer could actually be gleaning fruit flies or other tiny insects on the fruit. Being omnivores, hummingbirds balance their diet with spiders and insects as sources of necessary protein. 

"The last of the tomatoes are drying up on the vine."
