Glowing puffleg's do not migrate in flocks, so when breeding, males attract females by flying in a U-shaped pattern in front of them. The glowing puffleg is a species that is solitary, besides breeding. Males are only involved in mating with the female in the reproductive process. Both the male and female glowing pufflegs will have several mating partners. Males are only involved in mating with the female in the reproductive process.
The clutch usually contains two white eggs that are incubated by the mother. During the incubation, the father is protecting the territory surrounding the nest and the flowers they feed on. The chicks are born blind and immobile. To feed the chicks, the mother pushes food down her beak through the chick's throats and into their stomachs. The chicks rely on their mother for food for about two weeks, and are able to fly within 20 days of birth.
