Faunistic and bioecological notes of Península Valdés and Patagonia. XXVI. Behavioral studies of breeding Magellanic Penguin, Spheniscus magellanicus, at Bahia Janssen colonies, Chubut, Argentina

Abstract

During the breeding season 1970–1971, the author studied the breeding of Magellanic Penguin in a nesting colony at Janssen Bay, Tombo Point, Chubut (44°25'S and 65°33'24"W). Additional studies were made in the breeding season 1972–1973 and 1973–1974, in another nearby colony at Clara Point (43°53'S and 65°15'W). Data is given on pair formation, nesting, pairing behavior, laying and incubation, mortality, molt, migration and other behaviors. The diverse methods for field information included are: observations, drawings, ethogram schedules, adopting a displays code, photographs, circular censuses, square and linear transects, as well as marking with plastic collars, paint, tags and aluminium bands.
