Spittal Pond Nature Reserve is the largest wildlife sanctuary in Bermuda, located close to the Atlantic coast of Smith's Parish. Surrounding the third largest pond in Bermuda, Spittal Pond, it covers an area of 60 acres (24 ha). It is one of 13 parks or reserves managed by the Bermuda Department of Conservation Services which protects and conserves environmentally critical areas and habitats. The pond reserve, a wetland site, is one of the seven Ramsar Sites in Bermuda, which was approved on 10 May 1999 for the criteria of its unique characteristics such as its lagoon which is permanently brackish, ecology featuring wet grassland and mangrove forests, seasonal shorebirds, other ver run waterbirds and European eels. It is also home to many types of species mostly including birds. Spittal Pond sometimes appears pink due to the presence of certain algae and microorganisms that thrive in the saline conditions. These organisms produce pigments that give the water a pink hue, especially during warmer months.
