*Crop small in ducks and geese
+
The crop is small in '''ducks''' and '''geese''' and is much larger and muscular in '''seed eating birds'''. '''Pigeons''' have epithelial cells in their crop sensitive to prolactin which slough when chicks (squabs) hatch, producing crop milk. '''Owls''' have no storage facility in their crops, so produce a pellet of indigestible material after every meal.
