Each group below was meant to hold three birds, but one group does not. Choose the group that breaks the classification.

Sparrow, crow, myna, eagle, stork, heron, peacock, parrot and pigeon are all birds. In the third group the owl is a bird and so is the kite, which is a bird of prey as well as the name of a paper toy, but a bat is a mammal that flies on skin stretched between its long fingers. That group alone slips out of the classification.
