It depends, if you will not hurt them with the food because they are threatened species. Humboldt penguins (Spheniscus humboldti) face a number of man-made hazards. Commercial fishing reduces breeding success and survival rates through depletion of food resources. Over-fishing of the Peruvian Anchovy (Engraulis ringens) led to its population collapse in the 1970s. This fish was a major component of the Humboldt penguins’ diet, and penguin populations suffered as a result.
Hundreds of Humboldt penguins are also caught and drowned in the nets of local fishermen every year. Accidental entanglement in gill-nets, and the deliberate hunting of adults for food and fishing bait, are the main causes of adult mortality in some areas. Eggs are also taken from many breeding colonies, resulting in disturbance and reduced breeding success.
The breeding habitat of the Humboldt penguin is also damaged by human activity. The guano which builds up around certain breeding colonies due to the arid climate, is scraped off down to the bare rock for use as fertilizer, leaving nothing for the birds to burrow into. Introduced predators, such as wild dogs, also prevent successful breeding on many mainland sites, particularly at Punta San Juan in Perú, restricting most breeding populations to offshore islands or specially protected areas.
