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.

Common Eastern Wildrye

<em>Elymus virginicus</em>, the common eastern wildrye, is a native North American grass in the family Poaceae, currently not evaluated by the IUCN Red List. The species is documented in Denmark, Sweden, and the United States, and typically inhabits grasslands, wetlands, forests, and cultivated lands across its range in eastern and central North America. It is a cool-season, perennial bunchgrass that typically grows in moist to mesic habitats including riverbanks, floodplain woodlands, forest understories, and moist prairies. <em>Elymus virginicus</em> is recognized by its distinctive nodding seed heads with stiff, curved awns and is among the most widely distributed wild rye grasses in North America. The species provides important ecosystem services as a native ground cover, stabilizing streambanks and riparian soils against erosion, and offering habitat and food resources for grassland birds, small mammals, and invertebrates. Common eastern wildrye is also valued in ecological restoration projects for its adaptability to a range of soil conditions and its ability to establish quickly in disturbed habitats. As a forage grass, it is moderately palatable to livestock and wildlife. Biological traits of this species remain poorly documented in the scientific literature.
