Arabian green bee-eater


The Arabian green bee-eater is a species of bird in the family Meropidae. It has a patchy distribution in the arid regions of the Arabian Peninsula from Saudi Arabia south to Yemen and east to Oman and the United Arab Emirates, and has expanded its range north to the southern Levant over the past few decades.

Taxonomy

Although initially described as distinct species, the Arabian and African green bee-eaters were grouped with the Asian green bee-eater as the green bee-eater by Sibley and Monroe in 1990. However, in 2014, the IUCN Red List and BirdLife International again split them as distinct species. A 2020 study found significant differences in morphology and voice between all three species, so they were also split from one another by the International Ornithologists' Union in 2021.
Two subspecies are accepted:
  • M. c. cyanophrys - western and southern Arabian Peninsula from southern Israel and Jordan south through western Saudi Arabia to Yemen and the far east of Oman
  • M. c. muscatensis - eastern Arabian Peninsula, locally in the centre of the peninsula, in eastern Saudi Arabia and the United Arab Emirates south to eastern Oman

    Description

It is long excluding the elongated central tail feathers, which are an additional long. The head and back plumage is dull green except for a slender black eyestripe with a broad blue forehead and line above the black eyestripe, a conspicuous blue throat, and a broad black crescent at the top of the breast below the throat. The breast and underparts are blue-green. The most distinctive trait of this species is its bright blue throat and face, more intense than on either M. orientalis or M. viridissimus, and the central tail feathers are shorter. The wing and tail feathers are bronzed coppery-green above, and coppery-orange below. The iris is red, the bill is black, and the legs are dark grey. The juveniles are paler and duller overall, and lack the elongated tail feathers and black throat crescent. The species also differs from M. orientalis and M. viridissimus in its voice. M. c. muscatensis differs from M. c. cyanophrys in being slightly more yellowish-green above, and having a slightly narrower black crescent at the top of the breast.

Habitat

It has a patchy distribution in the arid, open regions of the Middle East with scattered trees, as well as wadis, gardens, and farmland, but avoids barren desert. Agricultural expansion and irrigation has created new optimal habitat for this species, and thus its population has grown, which allowed it to spread to parts of the Levant prior to 2001. Due to this increasing population and it benefiting from human habitat modification, it is not thought to be under threat.
