Field guide: Waterbirds of Aysén

Birdwatching evokes a sense of wonder and serenity, connecting us with nature and reminding us of the value of the biodiversity that surrounds us.

Many bird species today face threats such as habitat loss, pollution, and predation by introduced animals, which limits their opportunities for feeding and reproduction. Species whose conservation status is at risk, in particular, require increased monitoring efforts, making every new birdwatcher essential.

Conserving these species is crucial, as they play key roles in maintaining ecosystem balance, such as regulating pests and preserving the natural dynamics of rivers and other bodies of water. Furthermore, their presence and abundance reflect the health of the environments they inhabit: declining populations are often a sign of ecosystem disruption or deterioration.

This spring, we invite you to become a birdwatcher. The eBird platform offers a valuable citizen science tool that allows you to record and share the birds you find in your surroundings.
