a small birdhouse would be great idea. I really like animals especially birds, maybe because my mom didn’t let me have one when i was a kid. I used to take care of a bird used to build her nest on a tree in my backyard, i noticed that she comes like every spring so i bought her suet for birds and in the next day she comes with some other birds to eat, it was a really cute view. Now i take care of around 20 birds. They come every morning to my backyard to eat their breakfast lol !! and I built 3 birdhouses on the tree for them, And they started to build their nests inside the birdhouses.
