As I've mentioned before, birds just can't seem to get the hang of the concept that babies are supposed to be cute. Most of them start out horrendously ugly and gradually grow into those lovely, graceful creatures that so many people love.
This picture of three young Black Palm Cockatoos from the Jurong Bird Park in Singapore demonstrates the process - sort of. We've got a three week old baby in the middle with a two month old on the right and a three month old on the left.
But the black palm cockatoo is definitely a bird after our own hearts here at Ugly Overload because although it does get less ugly as it ages, it never entirely grows out of it:
Someone get that poor bird a hairdresser!
