This huge, beautiful and most famous Birdwing butterfly is a real forest dweller. Single males are often seen drinking salt water along sandy beaches on the west coast. On forest and mangrove habitats along the east coast males drink brackish water on muddy riverbeds. Except for forested habitats on the west coast, females are rarely encountered in absolute lowland areas. Both sexes are common up to at least 1000 m. above sea level, where they are very fond of visiting blooming trees and bushes – even during heavy down pours.
