The bee hummingbird's interaction with the flowers that supply nectar is a notable example of bird–plant coevolution with its primary food source (flowers for nectar). [ 4 ] [ 13 ] Flowers that bee hummingbirds often feed from are odorless, have long narrow tubular corolla that are brightly colored, and has dilute nectar.
The smallest is the 5 cm (2.0 in) bee hummingbird, which weighs less than 2.0 g (0.07 oz), and the largest is the 23 cm (9 in) giant hummingbird, weighing 18–24 grams (0.63–0.85 oz). Noted for long beaks , hummingbirds are specialized for feeding on flower nectar , but all species also consume small insects.
A molecular phylogenetic study of the hummingbirds published in 2007 found that the family was composed of nine major clades. [4] When Edward Dickinson and James Van Remsen, Jr. updated the Howard and Moore Complete Checklist of the Birds of the World for the 4th edition in 2013 they based their classification on these results and placed three of the nine clades in the subfamily Trochilinae.

Birds live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m (9 ft 2 in) common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds.
