Ecología reproductiva del Cormorán Imperial (Phalacrocorax atriceps), en Isla Deseada (Santa Cruz, Argentina)

We studied the breeding ecology of Imperial Shags (Phalacrocorax atriceps) in Deseada Island (Santa Cruz, Argentina), during the breeding season of 1994-95. The shags arrived to the island in early August, they re-builded their nests and started to lay eggs during late October, with a peak of egg pr...
