The only unstreaked pipit around here and a characteristic breeder of sand dunes is the Tawny Pipit and this one shows well, holding to the grass edge.

Having a biological child isn't supporting an exploitation industry and at odds with the goal of the cessation of animal use the way buying from a breeder or pet store is.
