My winter interest/camouflage plants can't touch it, but they do help to hide utilitarian items in the yard.
Some homeowners plant Nandina to provide food for cedar waxwing, American robin, Northern mockingbird, Eastern bluebird and other birds that depend on winter fruits to survive. Nandina berries last for months, attracting hungry birds when food is in short supply.
When dozens of cedar waxwings were found dead in Thomas County, Ga., Moges Wolderemeskel and Eloise L. Styer from the College of Veterinary Medicine, University of Georgia, found the cause to be Nandina berries.
All the birds had intact Nandina berries in their crops. There was hemorrhaging in the heart, lungs, trachea, abdominal cavity and other organs.
Nandina berries contain cyanide and other alkaloids that produce highly toxic hydrogen cyanide, which is extremely poisonous to all animals. Sudden death may be the only sign of cyanide poisoning, and death usually comes in minutes to an hour, Wolderemeskel and Styer report.

Nandina berries contain a toxin called cyanide. Birds in the US haven't figured out how to deal with the poison, and some cedar waxwing birds have died from eating lots of the berries. The berries can be toxic to any other animal too, so don't eat them. (It probably takes a lot of berries to hurt a large animal such as a human...still...don't eat them.)
Back to the original question: what's a good naturalist to do? That depends on who you ask. Some will say to never plant nandinas. Others say plant them but clip off the berries this time of year when birds start foraging. Others say don't worry about it - eventually the other species will adapt and nandina will become another important part of our ecosystem. The only problem with this last option is that adaptation takes hundreds to thousands of years, so we won't find out how nandinas mesh with our Middle Tenneessee ecosystem for a looooonnnngggg time!
What do you think we should do?

Personally...
I'm a fan of the bluestem...
And have been busily removing the nandina, ever since learning that it killed birds...

Bad enough that stuff is invasive...
