In 2015, as in other years, Great Blue Herons, Great Egrets, Snowy Egrets, and Black-crowned Night-Herons nested on West Marin Island (none on East Marin Island); however, all of the nesting Snowy Egrets and Black-crowned Night-Herons abandoned the site before completing the nesting cycle and, by 2 June 2015, only five Great Blue Heron nests and 26 Great Egret nests remained active (Kelly et al. 2015). The cause of the 2015 abandonments is unknown. In 2016, we found no evidence of successful nesting by herons or egrets on West Marin Island.
