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.

Comandra Blister Rust

<em>Cronartium comandrae</em>, known as comandra blister rust, is a parasitic fungal pathogen in the family Cronartiaceae that alternates between two unrelated host plants to complete its life cycle. The fungus infects coniferous trees, particularly pine species, during one phase of its development, causing characteristic blister-like galls on branches and stems that can girdle and kill infected tissues. The alternate host is typically comandra (<em>Comandra umbellata</em>), a parasitic flowering plant. On pine hosts, the rust forms orange or yellow spore masses during the aecial stage, releasing spores that infect comandra plants, where urediniospores and teliospores are subsequently produced. The species is distributed wherever its dual hosts co-occur across North America and parts of Eurasia. It can cause economically significant damage to pine plantations and natural forest stands. No quantitative biological metrics are recorded for this species.
