This was posted at an Arlington blog last May, but I just saw the sculpture it refers to.
“You are invited to watch the ladybugs for the Waldo Park Tree Sculpture being made right before your eyes … Work by artists has already begun to transform a tall tree stump on the hill in Waldo Park … into multimedia sculpture that features local birds, animals and insects. The Friends of Waldo Park are holding two community participation days as this work is created. …
“Watch the metal-smiths at work as they cast aluminum ladybugs to be bolted onto the tree sculpture. Stop by for however long you’d like to see how metal-casting is done!” More.
Note the metal ladybugs crawling up the trunk, the bunnies peeking out from inside, and the hawk on top.

Very cool!
And to think that my little grandson and I had been knocking on trees in the cemetery to find animals and never realized there were critters in a tree not far away!
Life is funny!
