yeah I've seen birds nesting on the device itself in places. Other animals acclimate to them, they might work if the animal has basically no reason to want to go there, if they want to they will.

The Home Depot here uses one in the garden area and I can't shop there for more than a couple minutes. our wal-mart used to have one in the produce section, fortunately finally removed.

Worst superpower ever.
