Amethyst-throated hummingbird, first ever in the USA

This video from the USA says about itself:

18 October 2016

The first-ever Amethyst-throated Hummingbird spotted in the United States spent the afternoon sipping from the Perky-Pet feeder on our West Texas Hummingbird Cam, making multiple visits throughout the evening. The mega-rarity was first spotted by the cam host, who also documented its presence with still images.

The West Texas Hummingbird Feeder Cam is nestled in the mountains outside Fort Davis, Texas, at an elevation of over 6200 feet. This site hosts a total of 24 Perky-Pet® Grand Master hummingbird feeders, and during peak migration can attract hundreds of hummingbirds from a dozen species that are migrating through the arid mountains.
