It’s not easy life as a Jacobean hummingbird, when you are a female. Building the nest, going to find something to eat and then feed the little ones: all these tasks fall to him while the man is taking it easy. Worse, all these chores are carried out under harassment of the males who steal her feathers, push her aside and peck her. You speak of a mental load!
But some females Florisuga mellivora have decided to take matters into their own hands by copying the shimmering plumage of the gentlemen, which allows them to go about their occupations neither seen nor known, scientists report this week in the journal Current Biology.
