Chestnut-fronted Macaw

A medium-sized macaw of Central and South American tropical forests from southern Mexico to Bolivia and Brazil, chestnut-fronted macaws have predominantly green plumage with a chestnut forehead, red shoulder patches, and blue flight feathers. The smallest of the true macaws, they inhabit forest edges, savannas, and secondary woodland and often raid crops, making them locally unpopular with farmers. They are popular aviary birds, but wild populations face pressure from trapping and deforestation.

Usnea cornuta is a fruticose lichen in the family Parmeliaceae, assessed as Near Threatened (NT). It forms shrubby, branching thalli that hang from tree branches and twigs, typically in humid forest environments. Like all Usnea species, it is highly sensitive to air pollution, particularly sulfur dioxide, making it a useful bioindicator of air quality.
