The Violet Sabrewing is one of the largest hummingbirds to be seen in Costa Rica; whenever these hummingbirds perched on the delicate branches, their weight and speed would made them swing very fast. This species has a fairly down curved bill. Most of the male’s body is deep, glittering violet, although some parts have a bluer hue. The underside of the tail feathers is white, while the wings are brown, with green-blue feathers on the shoulder. The female is drab in coloration, with gray underparts showing green and yellow sports, and green-yellow iridescence on the back of the head.
The Violet-tailed Sylph is part of the Aglaiocercus genus, containing two more species, one of them being the Long-tailed Sylph which we also saw in Colombia during our trip. It has a long tail that glows in purple from the back. Other than that, the bird is mostly green, with flashes of orange on the belly and blue hues on the back. Their bill is relatively short when compared with other hummingbird species on its range. When the outer tail feathers are molted, individuals can be seen with shorter tails, like in the pictures below, since those feathers are precisely the ones that grow very long.
The Violet-bellied Hummingbird is another of the cute hummingbirds we saw in Colombia. Its name is pretty descriptive, since the belly is a deep iridescent purple tone that looks metallic on the right light; on the shadow it looks blue instead. The throat and face also glow in light green sometimes, other times it looks dark green along with the back of the head. It has a long and thin black bill that’s used like most hummingbird to extract nectar from the deep cavities of flowers in Colombia. I saw this individual while walking down from Doña Dora’s restaurant. It was doing its early morning stretching routine.
The Empress Brilliant is a pretty big hummingbird with a weird face, due to it being elongated towards the start of the bill. The male is entirely green with an iridescent violet throat, and sports a long forked tail. The female instead has white underparts with green spotting all over. Overall the colors are very brilliant, which does match with this species name.
The Brown Violetear is a medium-sized hummingbird which has a violet ear patch, not surprising given its name. The body is mostly brown in coloration, with darker wing and tail feathers. The feathers covering its vent are whitish, as well as some of the throat feathers surrounding a small colorful patch in the center. It possesses a patch of green to blue iridescent feathers in the throat, something the Lesser Violetear does not possess. The black bill is relatively short and straight, which it uses to sometimes catch small insects on the flight. It is found in mid to high altitudes, particularly in humid areas where Porter Weed flowers are plentiful. Their small size and light weight let them perch in delicate branches without breaking them.
