Humboldt penguins fitted with copper vests aid healing

Researchers in Chile are testing red copper- and zinc-threaded recovery vests for injured Humboldt penguins to speed healing and deter infections, adapting similar pet-care tech for wildlife. The vests, inspired by successful uses in dogs and cats, are being measured and fitted to penguin sizes as part of an ongoing experimental effort. The project comes against a backdrop of a sharp decline in Humboldt penguin nests, with threats including fishing nets, pollution, disease, and competition for food, exacerbated by El Niño that affects prey availability. Early trials indicate the penguins tolerate the garments and that the fabric may protect wounds during recovery. Wildlife clinics across Chile report distressed penguins stranded along the coast, suggesting a growing need for new rehabilitation tools. The effort reflects a broader push to combine innovative materials science with wildlife conservation to improve recovery outcomes for vulnerable species.
