Least Concern

The white-booted racket-tail hummingbird is also known as the racket-tailed poofleg due to the two circles of white fur on the legs. Males are most notable for the long feathers running backwards from their body.

These animals are omnivores and will feed on nectar and invertebrates. During breeding season the females consume up to 2000 insets a day.

Females are responsible for caring for the chicks on their own. These are raised in a cup shaped nest formed from fibers and moss and held together using cobwebs.

Small numbers are collected to supply the pet trade.

Appearance

Across their body the males of this species have shiny green feathers. Females are white with green speckles on their underside. On their thighs are clumps of small white feathers. A white bar is present on their rump.

At the end of the body of the male are two long adornments which each end with a feather. The tail and the end feathers are colored blue.

An average white-booted racket-tail hummingbird will measure 17-23cm (6.5-19in) long with a weight of 3g (0.11oz).

Diet

What does the white-booted racket-tail hummingbird eat?

These birds are omnivores with their diet made up of nectar which they acquire using their long beak from flowers. They will also feed on small invertebrates.

Invertebrates are especially important to females feeding young. They may capture as many as 2000 per day during breeding season.

They favor certain flowers which produce nectar with high energy content. They will become highly protective of areas with these flowers.

They have been seen to make use of bird feeders placed by humans.

Reproduction

How does the white-booted racket-tail hummingbird produce its young?

Males will display at the start of the breeding season by completing speedy, swooping displays. The most impressive individuals will gain breeding rights with the most females.

After mating the male has no further involvement with their young.

Following a successful mating the female will go off alone to build her nest which is made from fibers and moss in a cup-shape. The nest is held together by an elastic bounding formed from cobwebs which can allow the nest to grow as the chicks do.

In to her nest she will deposit two eggs. At hatching young are immobile and covered by down.

The female will regurgitate food for the young which she pushes in to their stomach with the long bill.

Their mother will brood the chicks for the first 12 days of life. The chicks leave the nest at 20 days old.

Behavior

What does the white-booted racket-tail hummingbird do with its day?

While in flight these birds will beat their wings 60 times per second. They are able to fly sideways and backwards due to their unique beating pattern which resembles a figure-eight.

Males form a territory around blossoms and will chase off other hummingbirds and honeybees.

Outside of the breeding season these birds are considered solitary.
