It is rather common knowledge that "birders who hope to see hummingbirds often plant nectar-bearing flowers to attract them, but hummers aren't the only birds attracted to flowers."
This truism (or wisdom) is certainly evidenced by the photos directly above (taken in my garden a few years ago) where a male house finch seems to be enamored by my blooming Crabapple Tree while a female Baltimore Oriole is spending her time in the midst of my roses.
Birds also like to be among foliage as seen in the pictures below (also taken in my garden) where a mourning dove and a blue jay are of the leaves from my kiwi vines.
I coined the term "flora-ing" to describe the action of birds enjoying flowers and foliage.
More photographs and interesting facts re many types of birds and various flora is included in my book series, Words In Our Beak. Here's the purchase info:
