Blue-and-yellow Macaw

One of the most striking and widely kept macaw species, blue-and-yellow macaws display brilliant cobalt blue upper parts contrasting with vivid yellow underparts and green forehead. They inhabit forest, woodland, and savanna from eastern Panama through Venezuela, Brazil, and Bolivia to Peru and Ecuador. Highly intelligent, they live in pairs or small flocks, feeding on palm nuts, seeds, and fruit. Popular in aviculture for over 400 years, they can live 80+ years in captivity.

Micarea lignaria is a small crustose lichen with granular thallus and tiny grey-green apothecia, adapted to wood and bark substrates. It grows on bare acidic bark, wood, and sometimes peat in temperate and boreal forest environments. This photosynthetic lichen obtains energy through its algal partner and contributes to wood surface colonization.
