Green Thorntail ジグソーパズル

The Green Thorntail (Discosura conversii) is a small hummingbird that is a resident breeder from Costa Rica to western Ecuador. Hummings birds can hover in mid-air by rapidly flapping their wings 12–90 times per second. They can also fly backwards, and are the only group of birds able to do so.
