Nimbly they seized and secreted their prey,
Alive and wriggling in the elastic net,
Which Nature hung beneath their grasping beaks;
Till, swoln with captures, the unwieldy burden
Clogg'd their slow flight, as heavily to land,
These mighty hunters of the deep return'd.
There on the cragged cliffs they perch'd at ease,
Gorging their hapless victims one by one;
Then full and weary, side by side, they slept,
Till evening roused them to the chase again.

Canto IV, line 141. - The Pelican Island (1827)
