In the artwork, these active budgerigars play among colorful flowers and trees native to Australia.  The green bird is considered the normal variety, the common color of wild budgerigars.  The blue bird, known as the blue variety, lacks yellow pigment in its feathers.  The pale bird is called a cinnamon. In this variety the rich black melanin in the feathers is replaced with a tan color.  Although very different in appearance, these birds share a kinship of togetherness which shines through in this setting.
