The tree house

As I heard about the chicks of the blue herons' from Mr.Muir, so I went to see them from the viewing platform of the City Hall. But it was hard to see them because of far away and too high from there.
I couldn't see any of chicks just saw a parent heron on the top of the tree.

I was worried about their tree house and the unstable nest if the strong wind or storm might blow them away.
The higher the much harder shaken the tree would be.
May their tree house would be safe until the chicks are grown up.
I can't help praying for their wild life and survival.
