  1. Physically protect nests with individual exclosures/barriers or provide shelters for chicks of ground nesting seabirds

    A small study in 2003 on two warehouse roofs in Texas, USA (Butcher et al. 2007) found that least tern Sterna antillarum chicks did not use wooden shelters more than would be expected by chance. However, on 18% of occasions when adults were observed mobbing predators (n = 39), chicks were seen using either artificial plants or skylights as cover (on two occasions chicks ran towards structures, on five occasions chicks were already in cover).
