Buff-tailed Coronet (Boissonneaua flavescens)

The Buff-tailed Coronet is among the most common hummingbirds in the areas of Colombia we visited. Its body color is green in general, with a scaled pattern on the belly, although the back can look reddish under the right light. The wings are brown and are long enough to cover the tail when folded down and perched. The white postocular spot is a defining feature, along with the buffy shoulders and white feathers that cover their feet, similar to the Booted Racket-tail. The bill is short and straight, entirely black. They like to perch for a few minutes in small branches, and when their feel their personal space is threatened by other individuals, they may put up a fight on the wing. It may not be the flashiest in terms of colors and anatomy, but it sure is beautiful to watch. In Rio Blanco Natural Reserve where we first saw them, they swarm in big numbers around the feeders, fighting each other and with other species.

This is a very common hummingbird species in Colombia. I was able to photograph it in three places; this one was taken at Rio Blanco Natural Reserve.

It was common to see a pair of these hummingbirds perched in the same branch, and they sometimes would put on fighting each other for space.

Other times they perched alone, peacefully resting before flying again to drink more nectar, both from nearby flowers and from the feeders.

Their body is green in general, with dark brown wings. The bill is black from base to tip, very straight and short.

An important identification mark for this species is the white postocular spot, a feature that is pretty small.

Pairs of these hummingbirds would perch for a few moments in close proximity, particularly when resting from the high strain of feeding while hovering in the air.

Another defining feature for this species is the white feathers covering their feet. This is a trait it shares with the Booted Racket-tail.

In the right light, the back of the hummer can display reddish colors.

Like contestants preparing their spades for battle, face offs are frequent on these branches.

A closer look reveals a scaled pattern on the breast, and a subtle buffy coloration on the wing junction with the body.

Also in this picture, the white undertail coverts can be seen. Most of the time they are not visible.

This one looks very nice against a green background and perched on a moss-covered branch.

This other individual was photographed in Finca Alejandría, Cali. With this angle, the red and metallic orange colors come to life on the base of the tail.

Another close up from the front, with the white feathers visible on the feet.

On a different angle, the bird may look smaller, but the defining features are there.

On this one, the white feathers on the feet are very prominent, as well as the scale-like look on the chest.

These are very beautiful birds, although not the most flashy ones. Those will come later.
