3 Threats and security
List of references
Blue bush jay (lat. Aphelocoma coerulescens) Is a bird of the corvidae family that lives only in Florida.
Blue shrub jay 28 cm long. The nape, upper wing coverts and tail are bright blue. The back, underside and forehead are gray. There is a dark tape below the goiter. The ear coverts, as well as the underside of the wings and tail, the iris of the eyes, beak and legs are dark.
The area is limited to areas of Florida, overgrown with bushes. The preferred living space is more often in a transitional state - it is a bush that has arisen after the fires, consisting mostly of oak trees about 3 m high and small meadows.
3. Threats and security
The population of the species declined in the 20th century due to the destruction of living space by about 90%. In 1975 en: Florida Fish and Wildlife Conservation Commission and in 1987 the United States Fish and Wildlife Service (U.S. Fish & Wildlife Service) classified the species as endangered. Populations on the west coast of Florida are being accurately monitored and researched. For this, the animals are ringed in different colors so that they can be identified by looking through binoculars. The living space is protected or restored.
The award of the species status took place in 1995. This decision was confirmed by finds of bones from the Late Pleistocene, as well as molecular genetic and ecological conclusions.
