Sapphire-throated Hummingbird

Overview

The sapphire-throated hummingbird (Chrysuronia coeruleogularis) is a shiny metallic-green hummingbird found in Panama, Colombia, and more recently Costa Rica. The sapphire-throated hummingbird is separated into three subspecies; Chrysuronia coeruleogularis coeruleogularis, Chrysuronia coeruleogularis coelina, and Chrysuronia coeruleogularis conifis.
Measuring 9 cm (3.5 in), this hummingbird sports a distinctively forked tail, which helps to distinguish it from other similarly sized and colored hummingbirds. The male is metallic green overall, with a violet-blue throat and dark tail.
