Mink spread in Patagonia

Invasives are a worldwide problem...
In 1974, a bird new to science was discovered in Patagonia. Only a few decades later, it is now considered to be Endangered. Its numbers have fallen for various reasons, but the introduction of non-native trout has contributed to the decline. Introduced American mink have also been spreading in western Patagonia. When researchers visited one of their breeding sites in March this year, they found mink had devastated the colony. Over 30 breeding adults were killed, and over 40 eggs abandoned.
