Violet ear hummingbird / Orejivioleta ventriazul

Wikipedia : The Sparkling Violetear is the largest violetear at 13 to 15 cm (5–6 in) long. Male birds weigh 7.7 to 8.5 grams(0.27 to 0.3 oz) while females weigh from ounces 6.7 to 7.5 grams (0.24 to 0.26 oz). This hummingbird resembles the Green Violetear, but that species generally prefers more humid habitats, is obviously smaller and lacks the distinct purple-blue chest-spot and chin of the Sparkling Violetear.
