Stupid Robin!! He's attacking his own reflection in your window. Trying to drive off, what he believes is, an interloper into his territory. Anything to break up the reflection will cure his confusion. Strips of ribbon hung on the outside of the window work well. Duct Tape works, but it's messy to remove. Strands of yarn hung outside. Good luck!!
Because he's attacking his reflection for invading his territory.
Flies buzz because their wings move extremely fast. They create a buzzing sound as they fly because of their wings.
Since an average hummingbird beats its wings about 50 times per second, it could conceivably beat its wings 3,000 times over the course of one minute.The fastest hummingbirds, which can flutter at 80-90 beats per second, could conceivably beat their wings over 5,000 times in the course of a minute.
Honey bees have 2 pairs wings. The front wings are larger than the hind wings and the two are synchronized in flight with a row of wing hooks (humuli, singular: humulus) on the hind wing that hitch into a fold on the rear edge of the front wing. When the bee is at rest, the wings separate and fold flat against the thorax.

'Flit' is a word meaning to fly quickly or jerkily. It could be applied to flying insects or small birds, and possibly small insectivorous bats. I have also heard it used to refer to small water insects or fish that move quickly in short bursts.
When it is not flying.
I can flutter like a bird. Can you make your arms flutter like birds' wings?

you put our eyelashes on them and flutter them up and down like a butterfly flutters its wings

A red robin's wings beat about 2.3 times per second. This is equal to about 138 beats per minute.
