A Flight of Swallows

We've a flock of around 100 swallows that play around the house, and,once the breeze drops sometimes they hover around the windows picking off insects.

Today was one of those days.

'Flock' seems such a mundane word to describe a group of swallows, it should be something like a 'flight of swallows 'that would be so much more suitable.

So from today 'flight' it shall be.
