The images in this section are of unusual penguins. Images show either hybrid penguins (offspring of cross species mating), or penguins with unusual plumage. Both hybrid penguins and penguins with non-standard plumage are relatively rare.
In the case of abnormally coloured penguins, it is not known whether their colour patterns are genetic (i.e. if these penguins were to breed, would their offspring be similarly coloured?). It is also not clear whether abnormal colouring affects the penguins breeding success. Depending on their colouring some of these penguins may not survive for long as they may be relatively conspicuous to their predators.
