Sparkling violetear

The sparkling violetear (Colibri coruscans) is a species of hummingbird widespread in highlands of northern and western South America, including a large part of the Andes (from Argentina and northwards), the Venezuelan Coastal Range, and the Tepuis. It occurs in a wide range of semi-open habitats, even in gardens and parks within major cities such as Quito, and is often the most common species of hummingbird in its range. It is highly vocal and territorial.

The sparkling violetear is the largest violetear at 13 to 14 cm (5 to 5.5 in) long. Male birds weigh 5.8 to 8.5 g (0.20 to 0.30 oz) and females 6 to 7.5 g (0.21 to 0.26 oz). The nominate male's upperparts are metallic bluish green, the chin bluish violet, the belly blue, and the rest of the underparts green. Long erectile bluish violet plumes cover the ears. The tail is metallic green with a steely blue band near the end. Females are similar but smaller, and often have a white spot behind the eye. C. c. germanus is essentially the same as the nominate but the forehead, underparts, and tail are somewhat bluer.
