A before-and-after study on Ilhéu da Praia, Azores, Portugal (Pitta Groz & Pereira 2005), found that the breeding populations of common terns Sterna hirundo and roseate terns S. dougallii increased significantly from 1997 (approximately 100 pairs of common and fewer than ten pairs of roseate terns) to 2002 (641 pairs of common and 133 pairs of roseate terns), following the eradication of European rabbits Oryctolagus cuniculus in 1997 by brodifacoum poisoning. Common tern populations initially increased to approximately 950 pairs in 2000, before falling again.
