This video from the USA says about itself:

After the sad news of people killed and injured in Texas, some good news.
From the Cornell Lab of Ornithology in the USA:
We’re excited to bring you a second action-packed season of the West Texas Hummingbird Feeder Cam, sponsored by Perky-Pet®. This site is nestled in the mountains outside Fort Davis, Texas, at an elevation of over 6,200 feet. During peak hummingbird migration, this site hosts 24 Perky-Pet® Grand Master hummingbird feeders, attracting 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. Last year we started broadcasting during the height of the fall migration in September (check out the highlights); this year, you’ll get the opportunity to watch the diversity and abundance of these agile fliers grow throughout the summer, and get to know them one-by-one. Right now, the most common species on cam are Broad-tailed Hummingbirds, along with Black-throated, Magnificent, and soon, Rufous hummingbirds.
You may also hear or glimpse other common species of the arid mountain forests, including Western Scrub-Jays, Acorn Woodpeckers, and Canyon Wrens. From time to time you may hear researchers working in the background as they band hummingbirds nearby.
