Yellow-throated Nightingale-Thrush

The yellow-throated nightingale-thrush or Gould's nightingale-thrush (Catharus dryas) is a species of bird in the family Turdidae, the thrushes and allies. It is found from Mexico to Nicaragua. == Taxonomy and systematics == The yellow-throated nightingale-thrush was originally described in 1855 as Malacochicla dryas. The two subspecies of what is now the speckled nightingale-thrush (Catharus maculatus), also called Sclater's nightingale-thrush, were long treated as subspecies of the reassigned Catharus dryas. Together they were called the spotted nightingale-thrush. Following a study of the species' vocalizations published in 2017, taxonomic systems began separating them. The further taxonomy of the yellow-throated nightingale-thrush is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World assign it these three subspecies: C. d. harrisoni Phillips, AR & Rook, 1965 C. d. ovandensis Brodkorb, 1938 C. d. dryas (Gould, 1855) The Clements taxonomy does not recognize C. d. harrisoni but includes it within C. d. ovandensis. This article follows the three-subspecies model. == Description == The yellow-throated nightingale-thrush is 17 to 19 cm (6.7 to 7.5 in) long and weighs 36 to 44 g (1.3 to 1.6 oz). Adult males of the nominate subspecies C. d. dryas have a mostly black head with…
