Small but mighty. Let us introduce you...

Say hello to the rufous-tailed hummingbird. This female is sitting in her tiny nest. Males look similar – lots of green, just like the females, but males have a bit more glitter on the throat and breast. Both sexes have a reddish-brown (rufous) forked tail – hence the name. Rufous-tailed hummingbirds are found in forests, gardens and coffee plantations from southern Mexico down to the northern edge of South America, and they play an important role in pollination. Not to be confused with the smaller rufous hummingbird, which migrates through North America, the rufous-tailed is medium-sized and, like most hummingbirds, very territorial when it comes to protecting its favourite feeding spots.The females are the nest-builders of the pair, creating tiny cups out of plant fibres, cobwebs, lichen and moss. Females usually lay two eggs, which take between 15 and 19 days to hatch. The chicks will fledge, or get their flying feathers, about 20 days later. But they won't be fully independent from mum until they're about 50 days old. And dad? He doesn't participate in chick-rearing.
