We have two different bird families living in our grass roof.
They leave me little presents every morning, like this beautiful feather.
I thought they would be more scared of the cats but the fact is they love to swoop down low and tease them and then fly off again. The old ones knows it is next to impossible to catch them and would rather sleep, while our young kittens love the chase. To no avail. I've still to see them catch a bird.
