In Brazil, traffickers reportedly earn nearly $2 billion a year.

The country with the greatest biodiversity in the world is said to be one of the main exporters: it alone illegally moves around 38 million wild animals a year, 80% of which are birds, and often endangered species.

Many are intended for collectors or local breeders;

because here, it is a real tradition to own a bird at home.

This enthusiasm for birds hides a very lucrative illegal market.

With the help of the environmental police, Brazilian activists seek to save these endangered birds.

But under the outgoing presidency of Jair Bolsonaro, the environmental police budget has been drastically reduced, complicating their work.
