Chilean and international researchers found a 63% drop in active nests among Humboldt penguin colonies in 2024 and 2025 compared to three years prior. [^1]

Researchers in Chile designed red vests woven with copper and zinc to help injured Humboldt penguins heal faster. [^2]

Ignacio Idalsoaga, director of the Buin Zoo in Santiago, Chile, stated that vests with microfibers containing copper and zinc have been tested on pets for years to help recover skin wounds. [^3]

The vests are designed to inhibit the growth of bacteria and fungi using copper and zinc, while zinc also stimulates the formation of new blood vessels. [^4]

The Humboldt penguin population faces threats including entanglement in fishing nets, plastic pollution, disease outbreaks, and competition with the fishing industry for food. [^5]

Tomás Pino stated that the copper and zinc woven into the fabric inhibit bacterial and fungal growth, while zinc stimulates new blood vessel formation to speed up tissue healing. [^6]

Ignacio Idalsoaga stated that El Niño brings unusually warm waters to the Pacific Ocean, making cold-water fish harder to find and likely leading to abandoned chicks with injuries. [^7]
