There is disclosed an animal decoy (10) including a hollow base (11) and a cover (12) removably coupled to the base. The base has a lower portion or shell (14) releasably coupled together through latches (28) to define a storage space within the decoy. The cover is made of a flexible material which includes an iridescent cloth material portion. The base shells may be nestable to minimize storage space necessary for the decoys. The lower shell may also be replaced by another lower shell (60) of a different stance or configuration.
