About These Birds
King Penguin
The king penguin is the second-largest penguin species, known for its striking orange-gold head markings. Unlike most penguins, king penguins do not build nests — they incubate their single egg on their feet. Their 14-16 month breeding cycle is the longest of any penguin species.
Scarlet Macaw
The scarlet macaw is one of the most iconic tropical birds with its dazzling tricolor plumage. These highly intelligent parrots form lifelong pair bonds and can live over 75 years in captivity. They play an important ecological role as seed dispersers in Neotropical rainforests.
