Hummingbirds’ Furious Feeding Nearing the End
After an incredible fall on the West Texas Hummingbird Feeder Cam, activity is starting to wind down for the winter. Ten species were seen during this short season by viewers, often appearing in a bewildering array of immature and adult plumages to make identification a challenge. Together we learned the sometimes cryptic clues to puzzling out each species’ identity, and over 1500 of you hazarded guesses in our two Hummingbird ID Challenge contests (thanks to cam sponsor Perky-Pet® for the hummingbird feeder prizes). Hummingbirds weren’t the only ones visiting, either—butterflies and Acorn Woodpeckers made appearances on cam, too! Take a moment to tell us which hummingbird species were your favorites, and you could win a Perky-Pet® hummingbird feeder of your own!
Cold winter weather will eventually lead to the hummingbirds heading downslope or further south by late November. The cam will go offline in late November; only three short months before we should start seeing the first Broad-tailed Hummingbirds of spring arriving. Thanks for a great season!
Attracting hummingbirds in winter is possible in some areas! Learn where and how.
The name buff-bellied hummingbird doesn’t do justice to the colorful and attractive plumage of this medium-large hummingbird with its turquoise, rufous, green and creamy coloration. The iconic hummingbird of the Rio Grande Valley in south Texas, this hummer is a target bird for many birders visiting that area. This is one of very few hummingbird species in North America where males and females look similar: here.
