Hummingbird migration has begun
Expect sightings to increase across Oklahoma
The season is starting to change and the hummingbirds are responding.
With every cold front the past few weeks, more and more hummingbirds are moving through Oklahoma.
Late August to early September is when most hummingbirds will head south for the winter and flee the cool temperatures.
Ahead of migration, hummingbirds will gain 25 percent to 40 percent of their body weight to prepare for the trip south. So over the next few weeks, expect hummingbird activity to increase greatly.
Some locals have even reported more than 50 hummingbirds at their feeder at one time. In one instance, a 32-ounce feeder had to be refilled after a single day.
The ruby-throated hummingbird is one you will often see in Oklahoma. They weigh just 2.5 to 3.5 grams.
In proportion to their bodies, they have the largest brain and wing muscles of any animal. Their wings can beat 70 times a second when hovering and around 200 times a second when diving and flying.
