Reproductive and nutrition biology of the Petrels (Biologia reproductiva y nutricia de los Petreles)

Breeding and feeding biology of fulmarine and hidrobatyds petrels at Antarctica Peninsula and Scotia Arc Islands is studied. The investigation includes studies on petrel breeding chronology; egg morphology and chick growth; breeding success; diet; activity; and energetic budget. Periodic sampling of food items is conducted to analyze caloric contents and estimate food availability.
