-Over a period of four years, nineteen adult Humboldt Penguins (Spheniscus humboldti) banded at a colony on Islote Pijaro Nifio near Algarrobo, Chile were recovered or sighted at locations away from the colony. Eighteen birds were found dead, and one bird was sighted alive at another breeding colony. Eight of the penguins were found entangled in fishing nets, while the circumstances of death for the other ten birds were unknown. Dead birds were found three km to 592 km from Algarrobo. The live bird was sighted approximately 88 km north. These data indicate that adult Humboldt Penguins may visit other breeding colonies and corroborate previously published data that Humboldt Penguins may travel long distances from their breeding colony. Our data also indicate that accidental drowning in fishing nets is a cause of mortality in this species. Received 3 March 1999, accepted 28 April 1999.
