Каштановолобый ара

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.

European otter

Sleek semi-aquatic mustelid found along clean rivers, streams, and coastlines across Europe and Asia. European otters can reach 1.3 meters in length and are highly skilled fish hunters, using sensitive whiskers to detect prey movements. Requiring unpolluted water with abundant fish, they are an indicator species for freshwater ecosystem health. Once nearly extinct in Western Europe from hunting and pollution, populations have recovered significantly following water quality improvements.
