Eos is a genus of parrots belonging to the Lories and lorikeets. There are six species which are all endemic to islands of eastern Indonesia, most within very restricted ranges. They have predominantly red plumage with blue, purple or black markings. Males and females are similar in appearance.

Their habitats include forest, coconut plantations and mangroves. They gather in flowering trees to feed on nectar and pollen with their brush-tipped tongues. Fruit and insects are also eaten. They make nests in tree hollows generally high in old large trees. Threats to these parrots include habitat loss and trapping for the cagebird trade, and one species, the Red-and-blue Lory, is classified as endangered.

The plumage of Eos lories is predominantly red, set off with blue, purple or black markings. They range in length from 24 cm (9 in) in the Blue-eared Lory to 31 cm (12 in) in several of the larger species. The bill is orange-red, the irises are reddish to reddish-brown, and the legs are grey. Males and females are identical in external appearance. They have a musky odour, especially noticeable in the Black-winged Lory, which is retained even in museum skins. Juvenile birds are partly striated owing to feathers with darker or dusky tips, and they have orange-brown to black beaks.

In Greek mythology, Eos ( /ˈiːɒs/; Ancient Greek: Ἠώς, or Ἕως "dawn", pronounced [ɛːɔ̌ːs] or [éɔːs]) is the Titan goddess^{[Full citation needed]} of the dawn, who rose from her home at the edge of Oceanus.

Eos is cognate to Vedic Sanskrit 'Ushas', the goddess of dawn. Also see Dawn goddess

The dawn goddess, Eos with rosy fingers opened the gates of heaven. In Homer, her saffron-coloured robe is embroidered or woven with flowers; rosy-fingered and with golden arms, she is pictured on Attic vases as a beautiful woman, crowned with a tiara or diadem and with the large white-feathered wings of a bird.

From The Iliad:

Quintus Smyrnaeus pictured her exulting in her heart over the radiant horses (Lampos and Phaithon) that drew her chariot, amidst the bright-haired Horae, the feminine Hours, climbing the arc of heaven and scattering sparks of fire.

She is most often associated with her Homeric epithet "rosy-fingered" (rhododactylos), but Homer also calls her Eos Erigeneia:

Hesiod wrote:

Thus Eos, preceded by the Morning Star, is seen as the genetrix of all the stars and planets; her tears are considered to have created the morning dew, personified as Ersa or Herse. Eos is the daughter of Hyperion, a bringer of light, the One Above, Who Travels High Above the Earth and of Theia, The Divine. Her brother was Helios, the Sun god and her sister was Selene, the Moon goddess. Her team of horses pull her chariot across the sky and are named in the Odyssey as Firebright and Daybright.
