Peru's southern Amazon — the Madre de Dios region — is being lost faster than almost any equivalent rainforest on Earth. Illegal alluvial gold mining clears the forest, and the mercury used to bind the gold enters every river it touches. Animals that escape the bulldozers do not escape the water.
What should you know about the problem?
- Over 100,000 hectares of Peruvian rainforest have been cleared by illegal mining in the past 15 years.
- Substantial amounts of mercury enter the Madre de Dios watershed every year.
- Mercury bioaccumulates: river fish, then river otters, then capuchin monkeys and macaws drinking from clay licks all carry elevated levels.
- Scarlet macaws (Ara macao) and red-and-green macaws (Ara chloropterus) depend on Madre de Dios clay licks for essential minerals.
Why this region matters?
Madre de Dios is one of the most biodiverse places on the planet — home to over 1,200 bird species, 200 mammal species, and a substantial share of the Amazon's macaw population. Losing it does not only harm the animals; it changes the ecology of the entire western Amazon basin.
What WARN is preparing to do?
WARN's Peru programme will fund a forest sanctuary for primates and macaws confiscated from the pet trade, support training for officers on field-confiscation triage, and contribute to mercury-awareness work with riverside communities. We need supporter funding to begin.
Is it true that we need your support to make this happen?
World Animal Rescue Network is at the launch stage of this work. We do not yet have rescue numbers to share — and that is exactly why your support matters now. Every donation helps us put trained teams on the ground, secure veterinary supplies and equipment, and reach the first animals before they are lost.
Donate today to fund our first deployments, or sponsor an animal to back a specific species through rehabilitation. You can also join the network as a volunteer, fundraiser, or monthly supporter.

What is this briefing not?
This briefing is not a substitute for the full this subject wildlife guide, not a pet-care manual, and not a first-person field dispatch. It is a desk-researched explainer for people who searched a specific question about this subject. The setting is MADRE DE DIOS, PERU.
Mercury and Machines: How Illegal Mining Threatens Peru's Amazon Wildlife sits in the newsroom as a briefings explainer. It is not a Field notes dispatch from a partner clinic, and it is not a reason to keep this subject. Location context: MADRE DE DIOS, PERU.
Who should skip this page?
Skip this page if you wanted a complete IUCN-style species profile, veterinary advice, or permission to keep this subject as a pet. You will not find those here. Read the wildlife guide next if you need status, range and sources in one place.
Skip it if you needed veterinary instructions, a travel itinerary, or a fundraising story dressed up as science. The skip is the point: a page that cannot say no is not a guide.
How does this briefing compare to the full species guide?
This page answers the search in the headline. The wildlife guide answers status, threats, and what is actually known. Use both; do not cite the listicle as if it were the Red List. In Madre de Dios, illegal gold mining clears rainforest and releases mercury into rivers.
What is the catch with a short wildlife briefing?
The catch with wildlife listicles is that a true fact can still be the wrong takeaway. “Amazing” is not the same as “safe to keep”, and a number without a source is trivia. Every figure on this page should be read against the cited IUCN or zoo pages, not against a screenshot.
Factory “12 facts” pages elsewhere on the web pad the same three sentences. Here each heading is a real question, each answer is meant to stand alone, and the sources at the end are the audit trail. If a number is not on this page or in those sources, we did not invent it.
What should you do after reading this?
Use this briefing to answer the question in the title, then go to the species guide for status and sources. If you want to help this subject, fund habitat and enforcement — do not buy the animal. In Madre de Dios, illegal gold mining clears rainforest and releases mercury into rivers.
If you want to support WARN’s partner work, donate knowing we are a community interest company, not a registered charity. If you want the animal itself, you have the wrong page.
Read the verdict on the first screen, the skip-if before you share the page, and the sources at the end before you quote a number. That is the whole contract of this briefing.
