Of course, it’s not just insects that like the willow tree and make use of it. There are birds as well, and our cats, and fungus. It really has a life of its own.
The kookaburras find it a great place to sit while worm watching.
The eastern spinebill use it as a place to survey the land
And fungus grows on it too. I have a feeling this is where the tree cracked and broke eventually.
