Oil spill
Some Humboldt penguin colonies face emerging pressures from industrial development; the construction of coal-fired power plants and mining proposals in Chile. Peru's largest colony faces the prospect of a major new industrial port in close proximity to the country's largest colony, at Punta San Juan. Oil spills have previously impacted some colonies. The colony of 800 birds at Cachagua was exposed to two oil spill events in 2015-16. Oil spills related to port and shipping activities have impacted many species of penguins across the southern hemisphere.
