Hovering around the flowers

Hummingbirds are attracted to the bright red color of the cardinal flower.  From these delicate, trumpet-shaped flowers, the hummingbird receives sweet nectar.  In return, the cardinal flower depends on the hummingbird for pollination.

Across the downs a hummingbird
Came dipping through the bowers,
He pivoted on emptiness
To scrutinize the flowers.
