It’s a beautiful piece of garden art..it took a little over 45 min for me to assemble.  
One problem is that it did  NOT work as a bird bath, instead worked as if a scarecrow!  It scared most of wild birds away in our wide open backyard so we had to move it to our front yard which is smaller and has lots of shrubs to blend in. 
There, still I haven’t seen any birds using it as a bath...but birds are back in our backyard after the birdbath is gone.  I think we may need a generic shape birdbath for our backyard rather than this realistic heron one...but again it’s great piece as a garden decor.
