Parrots attack: Argentine city suffers bird infestation

66

The town of Hilario-Ascasubi has a real parrot problem. Thousands of green, yellow and red birds have filled the streets, damaging electrical cables and causing frequent blackouts.
Biologists say this invasion is due to deforestation in the surrounding hills, forcing the birds to seek food and shelter in the cities.
Each year the parrots are to the city in the fall and winter, with as many as 50,000 birds per 5,000 local citizens. In the summer, they migrate south to Patagonia to breed.
