WING?!

WING?!
Saw this at the Detoit Zoo. It's the the "Bird Wing!" Get it? Bird? Wing? I don't know why I found this so amusing. I guess I was expecting "Aviary Pavilion." Or "Aviary Exhibit." Or even just "Aviary." Should I be on the lookout for the "Arboretum Branch?"

I think Matilda is pulling our leg...er, WING!
