Why Do Birds Flick Their Tails?
Tail flicks can be as unique as songs.

The way that some birds flick, wag, or flare their tails can be distinctive. A flicking or flashing tail might suggest to a predator that a bird is particularly alert or hard to catch, while also warning others in the flock of danger. Tail flicking can also help flush out prey. A Hooded Warbler -- or a Song Sparrow, like this one -- may flare its tail while foraging low to the ground to cause insects to jump, making them easier prey.

Why Do Birds Flick Their Tails?
Written by Bob Sundstrom
This is BirdNote.
The way that some birds flick, wag, or flare their tails can be as unique to a species as their song.
[Dark-eyed Junco song, https://macaulaylibrary.org/asset/42250, 0.12-0.14]
A junco foraging on the ground rapidly flashes white tail feathers that normally remain hidden.

When a Song Sparrow walks, hops or flits from bush to bush, its tail flicks jerkily up and down.

What’s it all about? One reason is that a bird’s repeated, habitual movements communicate information. Kind of like a person using hand gestures to signal to others. The tail flicking can also be used to deceive predators or to flush out prey.
A flicking or flashing tail might suggest to a predator that a bird is particularly alert or hard to catch, while also warning others in the flock of danger. When a hawk dives at a flock of juncos, there is an instant eruption of white flashing tails — a visual yell — which may distract a hawk’s aim at a single junco.

While we often focus on their calls and songs, there's a lot you can learn about what birds are communicating by watching their tails.
