Nest defence by Chinstrap Penguins Pygoscelis antarctica in relation to offspring number and age
We manipulated clutches of Chinstrap Penguins to examine the effects of brood size and offspring age on brood defence levels. Nest defence intensity increased with increasing offspring age. Experimental birds reduced nest defence intensity after losing one egg. These results support predictions deri...
