Cock's-spur

The cock's spur (Erythrina eggersii) is a small to medium-sized deciduous tree in the family Fabaceae, classified as Endangered and endemic to the Caribbean region, with its range restricted to a limited number of eastern Caribbean islands. Like other members of the genus Erythrina — the coral trees — it produces large, vivid red flowers that are a primary nectar source for hummingbirds and other nectarivorous birds, which serve as the tree's principal pollinators. The common name refers to the spurred or claw-shaped petals of the flower, characteristic of the genus. Erythrina eggersii is threatened primarily by habitat loss through agricultural conversion, development, introduced herbivores including goats and cattle that browse regenerating seedlings, and the extreme vulnerability of island endemic species to stochastic events such as hurricanes and droughts. The restricted range, small total population, and ongoing habitat decline place this species squarely in the Endangered category under IUCN criteria. Caribbean islands support disproportionately high levels of plant endemism but also suffer from among the highest rates of habitat conversion and invasive species pressure of any region globally. Conservation priorities for E. eggersii include protection of remaining native dry forest fragments, control of invasive herbivores, and ex situ cultivation as insurance against further population decline. The species was named for the Danish botanist Hans Franz Alexander von Eggers, who collected extensively in the Caribbean during the nineteenth century.
