Eastern Bluebird

Bermuda (2014)

The first and most drastic decline of the bluebird population occurred in the late 19th century when the House sparrow was introduced. The aggressive and adaptable sparrow multiplied rapidly and soon became the most abundant bird in Bermuda. The sparrow, as a hole-nester, rapidly displaced the bluebirds from the eaves of houses and soon began taking over the cliff holes and hollow of the cedar trees as well.

By the 1930's the natural bluebird nestlings were confined almost exclusively to holes in the trunks of cedar trees. The cedar scale endemic in the late 1940's and early 1950's killed over 90% of Bermuda's cedar forest. In an attempt to remove the eyesore and reforest the island the Government and private landowners felled most of the dead cedars destroying many ideal-nesting hollows.
