Overview
- Camera traps in the Brazilian sector near Foz do Iguaçu captured the images in December 2025, showing healthy cubs estimated at five to six months old.
- With this litter, Janaína becomes the most prolific female recorded by Iguazú monitoring since systematic surveys began.
- Researchers will continue tracking the family, determine the cubs’ sex when possible, and invite a community vote to choose names.
- Proyecto Onças do Iguaçu, a program linked to Brazil’s ICMBio, leads monitoring with camera-trap data and local participation to guide protection.
- Iguaçu National Park holds roughly 25 jaguars and is the only Atlantic Forest stronghold showing sustained growth, even as fewer than 300 remain regionwide and threats like poaching, illegal capture, road kills and disease persist.
