The ʻōmaʻo (Myadestes obscurus), also called the Hawaiian thrush, is an endemic species of robin-like bird found only on the island of Hawaii.

[1] The ʻōmaʻo was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae.

[3] Gmelin based his account on the "Dusky fly-catcher" that had been described in 1783 by the English ornithologist John Latham in his book A General Synopsis of Birds.

[5] Adult thrushes (males and females are similar in appearance) are mostly nondescript, with a grayish-brown head transitioning to a pale gray below.

[8] Their many calls include a catlike rasp, a frog like croak and even a high pitched police whistle type sound.

Today it is restricted to the southern and eastern slopes of the island, mostly above 1,000 meters above sea level, 25 to 30 percent of its ancestral habitat.
