Abstract. – Colony attendance patterns of Magellanic Penguin (Spheniscus magellanicus) at Isla Martillo, Beagle Channel, Tierra del Fuego: guidelines to minimize human disturbance. – The aim of this study was to analyze the daily activity pattern in Magellanic Penguins (Spheniscus magellanicus) at Isla Martillo, Tierra del Fuego, Argentina. Departure and arrival times were evaluated throughout the breeding cycle and the frequency distribution of penguins at sea estimated. The frequency distribution of arrival and departure times between the three different stages and within each stage varied throughout the day. This variation indicated a dynamic pattern for both activities. Nevertheless, a range time with lower activity was found for the colony. Furthermore, differences on peak activities with other colonies were noted. Given these results we suggest that tourist management should be site-specific, and recommend that bird-watching and guided visits take place from 10:00 to 17:00 h in order to minimize disturbance during the peak activities of penguins at Martillo Island.
