Swallows.

The swallows are swooping around the garden all day.

To watch them is a joy, their ability at flying ,wonderful.

We have to keep the doors of the house and the barns closed as they want to come inside to build nests.

Having three cats its not a good idea to let them build inside, to fly all the way from Africa to risk the fate of the cats finding their nests is not one to even think about.
