The Anna’s Hummingbird was named after Anna Massena, Duchess of Rivoli, a European noblewoman in Italy during the 19th century.
Due to the Anna’s Hummingbird’s high metabolism, they must eat constantly, feasting on nectar and insects to give them the energy they need for flapping their wings at incredible speeds.
