Guess How Many Hummingbird Species Visit in 30 Seconds

12 July 2016

This 30s clip from our West Texas Hummingbird cam features a variety of male and female hummingbirds visiting the feeder. How many species could you distinguish between? Can you name the species? Answers are at the end. Thanks for watching!

You can watch live anytime here.

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.

For the past 10 years, researchers from West Texas Avian Research have been banding hummingbirds at this site and others throughout the Trans-Pecos region of Texas to study the status and distribution of hummingbirds throughout the poorly known region.

The active banding of hummingbirds continues (off camera) at this site in the Davis Mountains, and from time to time you may hear researchers working in the background. Some common species in you may hear vocalizing include Western Scrub Jays, Acorn Woodpeckers, and Canyon Wrens (among others).

Thanks to West Texas Avian Research for their enthusiasm and support for hosting the camera at this remote research site, and to cam sponsor Perky-Pet®.
