Restore or create coastal and intertidal wetlands Bird Conservation

A before-and-after study of a large-scale wetland restoration project in Chesapeake Bay, Maryland, USA (Erwin et al. 2007), found that five out six ‘priority species’ colonised the site before 2005 after restoration began in 2002 (although the project was started in 1998). Snowy egret Egretta thula, cattle egret Bubulcus ibis, osprey Pandion haliaetus, common tern Sterna hirundo, and least tern S. antillarum all bred, with over 800 pairs of common terns. American black duck Anas rubripes, however, had not colonised the site by 2005. The authors note that tern reproductive success was very low, largely because of predation.
