The base needs to be a little heavier to keep it from being blown over. In all fairness these are the facts: Mine is standing in the middle of an empty birdbath and I do live in Oklahoma. However the base isn't flat which contributes to the instability. It's probably 1/8" to 1/4" off. And of course if it rains, the little guy floats because it's resin, not concrete. Bottom line is it probably have to set him back up once a week.
