Diet and feeding

The long-tailed sylph feeds on nectar (as of many other hummingbirds), insects, and, at times, small spiders. Flowers with higher sugar content are often preferred. They can be seen at hummingbird feeders, as well. A long-tailed sylph can lick nectar up to 13 times per second!

Courtship strategy

The male long-tailed sylph carries characteristic elongated tail feathers. These feathers are so ridiculously long that they hinder his flight: it is difficult for him to carry such finery every day when he relies on his flying skills to survive . Female sylphs, whose tails are of a more modest size, pick out and mate with the males with the longest tail feathers. They therefore ensure that they are mating with a male who is so fit and healthy that he can live well enough to come into breeding condition even when carrying a heavy load. Females do not possess these long tail feathers, as to make laying and incubating eggs easier.

gollark: Ah, I misread it, the problems I thought were problems were not problems.
gollark: That too, I missed that.
gollark: Ah, so there are several problems here.
gollark: I mean, it might internally, but it works fine anyway.
