This hummingbird, like other birds preparing to migrate, stores fat as a fuel reserve, thereby augmenting its weight by as much as 100%, hence increasing potential flying time over open water.
Este colibrí, igual que outras aves que se preparan para migrar, almacena graxa como reserva de combustible, aumentando o seu peso ata no 100%, incrementando así o seu tempo de voo potencial sobre mar aberto.
