There has been a pari of swallows coming into our house every day for a few weeks now. They were trying to make a nest on the wall in the hallway near our bedroom. They bring mud and straw, weeds, etc., spit it onto the wall and usually it will make a nice nest. Our wall is sand, and after several days of them building a nest and it kept falling off to the floor because the sand wall was not strong enough to hold it, I put up a wire mesh, hoping it would make it easier for their nest to catch.
Now, they still come in every day, they sit on the mesh, but they seem to have given up on trying to make the nest. I worry that keeping the window open is preventing them from finding a better place where they can make a home.
And the other day found this guy on the side of the road.
