Birds-of-paradise are a remarkable group of birds from New Guinea and Australia showing extreme sexual dimorphism. Males are incredibly ornate and loud and are not subtle at all. Females, on the other hand, are drab and probably easily overlooked in dense Australasian rainforests.

Birds + testosterone = sillyness. This gives me an idea about a future post about enlarging avian testes and daylength.
