I looked it up. Emus have three toes and ostriches have two toes. (Ostriches are also bigger. Who knew?)
The bird my wife found at Home Goods has three toes.
Both birds' meat is red rather than white. At first, I thought maybe the emu was claiming it was an ostrich to avoid being eaten, but apparently both are eaten.
Either way, the bird on our back deck took a fearsome barrage of acorns in recent days.
We will take it inside for the winter, along with the stork and the penguin, also from Home Goods.
