Then, do petrels eat penguins?

Petrels are highly opportunistic feeders. Unique among procellarids, they will feed both on land and at sea; in fact, they find most of their food near coastlines. On land, they feed on carrion, and regularly scavenge the breeding colonies of penguins and seals. At sea, they feed on krill, squid, and fish.
