The bee hummingbird, zunzuncito or Helena hummingbird (Mellisuga helenae) is a species of hummingbird which is the world's smallest bird.[2][3] It is native to Cuba.
Description[]
The bee hummingbird is the smallest living bird.[2] Females weigh 2.6 g (0.092 oz) and are 6.1 cm (2.4 in) long, and are slightly larger than males, which have an average weight of 1.95 g (0.069 oz) and length of 5.5 cm (2.2 in).[4] Like all hummingbirds, it is a swift, strong flier.
The male has a green pileum and bright red throat, iridescent gorget with elongated lateral plumes, bluish upper parts, and the rest of the underparts mostly greyish white.[2][5] Compared to other small hummingbirds, which often have a slender appearance, the bee hummingbird looks rounded and plump.
Female bee hummingbirds are bluish green with a pale gray underside. The tips of their tail feathers have white spots. During the mating season, males have a reddish to pink head, chin, and throat. The female lays only two eggs at a time, each about the size of a coffee bean.[2]
The brilliant, iridescent colors of the bee hummingbird's feathers make the bird seem like a tiny jewel. The iridescence is not always noticeable, but depends on the viewing angle. The bird's slender, pointed bill is adapted for probing deep into flowers. The bee hummingbird feeds mainly on nectar, by moving its tongue rapidly in and out of its mouth. In the process of feeding, the bird picks up pollen on its bill and head. When it flies from flower to flower, it transfers the pollen. In this way, it plays an important role in plant reproduction. In one day, the bee hummingbird may visit 1,500 flowers.[6]
Diet[]
The bee hummingbird has been reported to visit 10 plant species, nine of them native to Cuba. These flowers include Hamelia patens (Rubiaceae), Chrysobalanus icaco (Chrysobalanaceae), Pavonia paludicola (Malvaceae), Forsteronia corymbosa (Apocynaceae), Lysiloma latisiliquum (Mimosaceae), Turnera ulmifolia (Passifloraceae), Antigonon leptopus (Polygonaceae), Clerodendrum aculeatum (Verbenaceae), Tournefortia hirsutissima (Boraginaceae), and Cissus obovata (Vitaceae).[7] They occasionally eat insects and spiders. In a typical day, bee hummingbirds will consume up to half their body weight in food.
Habitat and distribution[]
The bee hummingbird is endemic to the entire Cuban archipelago, including the main island of Cuba and the Isla de la Juventud in the West Indies.[4] Its population is fragmented, found in Cuba's mogote areas in Pinar del Rio province [8] and more commonly in Zapata Swamp (Matanzas province) and in eastern Cuba, with reference localities in Alexander Humboldt National Park and Baitiquirí Ecological Reserve (Guantanamo province) and Gibara and Sierra Cristal (Holguin province).[9]
Breeding[]
Males in the bee hummingbird clade court females with sound from tail‐feathers, which flutter during display dives.[10] The bee hummingbird's breeding season is March–June, with the female laying one or two eggs.[11]
Using strands of cobwebs, bark, and lichen, female bee hummingbirds build a cup-shaped nest about 2.5 cm (0.98 in) in diameter, lining the nest with soft plant fibers. Branches in mature, leafy Jucaro (Bucida buceras) and juvenile Ocuje (Calophyllum antillanum) trees are commonly used for nest building.[citation needed] After completion of the nest, the eggs are in fledge by incubation for 21 days by only the female, followed by 2 days of hatching, and 18 days of care by the mother. Over the last 4-5 days of nestling, juvenile bee hummingbirds practice their flight capabilities. The nests are used only once, then degrade by rain and other natural factors.[11]
Coevolution with flowers[]
The bee hummingbird interaction with the flowers that supply nectar is a notable example of bird–plant coevolution with its primary food source (flowers for nectar).[2][3]
