Drapeau, P., McNeil, R., Burton, J. (1984) The influence of human disturbance and the activity of the double-crested cormorant Phalacrocorax auritus on the reproduction of the great blue heron Ardea herodias on the Magdalen Islands. The Canadian Field-Naturalist, 98(2):219-222. (Scopus )

Résumé

In 1979, when human disturbance was frequent, only 6 of the 17 nests produced fledglings and the other 11 were deserted at the beginning of the breeding activities. Twenty-five of the 49 eggs laid were lost; 17 fell to the ground after the nests had been demolished by double-crested cormorants, and 8 were robbed or broken by common ravens Corvus corax and great black-backed gulls Larus marinus. In 1980, when human disturbance was minimal, only one of the 14 active nests was abandoned before the hatching of eggs. On average, 2.86 and 3.07 young herons respectively were produced per active and successful nest in 1980 as opposed to 0.88 and 2.5 in 1979.-from English summary
