Loxops is a Hawaiian honeycreeper genus in the finch family, Fringillidae. Most of them are commonly known as ʻākepa.

There are 5 species in this genus, two of which are recently extinct or possibly extinct:

Molecular analysis supports the genus diverging from its closest relatives, the Chlorodrepanis ʻamakihis, during the earliest Pleistocene, about 2.47 million years ago. The clade containing both genera is sister to the genus Magumma, which contains the ʻanianiau, from which they diverged during the latest Pliocene, about 2.78 million years ago. Genetic analysis of the extant species supports L. mana as being the most basal extant member of the group, diverging from the other species slightly later in the Pleistocene at about 1.9 million years ago, with L. coccineus and L. caeruleirostris diverging 600,000 years after L. mana. The phylogenetic position of the extinct species is not known.

Loxops average the size of 11 cm. They are considered a finch-like bird that also have a notched tail. Their bills have a cone shape to them and they are pale blue with a dark tip. They are also hard to find in the field. Males typically are a darker shade of green on the top while their belly-side is yellow. They also have a black mask that covers their face up until behind its eye while its forehead, forecrown, and backside is also yellow. Females resemble the same colors as the males, but the colors are muted and less vibrant.

The ʻākepa (Loxops sp.) are a group of one of the smallest Hawaiian forest birds, at four inches long and weighing 10 grams. They are placed in the genus Loxops. Only one of the species in the genus, the Hawaiʻi ʻākepa, is still extant, and is classified as Endangered by the IUCN. Previously considered conspecific, the group was split into distinct species in 2015. Found only in high elevation old growth rainforest, these nonmigratory passerines have rounded heads, black eyes, and black wings and tail. Adult males sport one of the most brilliant orange colors found in any bird, a plumage which takes four years to develop. Females are greenish gray on back, lighter gray on front, with varying amounts of yellow and sometimes pale orange on the breast and belly. Juveniles appear similar to females, though are generally duller in color.

All ʻākepa have an unusual cross-bill. When closed, the upper bill tip slightly overlaps the lower bill tip to one side (this cannot be seen in the field). When opening the bill, as in prying open leaf buds to extract small caterpillars, the bills swing dramatically sideways, and this is easily seen in the hand. Some birds cross one way, and some the other, apparently randomly. The ʻākepa cross-bill operates similarly to that in the North American crossbills (genus Loxia), but is much less obvious when the bill is closed.

Hawaiʻi ʻākepa are usually found from 1,500 to 2,200 meters above sea level. They are non-territorial, and group male displays have often been observed in the beginning of the breeding season. They participate in mixed-species flocks during the non-breeding season. ʻĀkepa is a Hawaiian term meaning "agile", befitting their active foraging at branch tips.

The Loxops commonly breed during the months of March and April and possibly during the months of February to June. The nests of the Loxops are found in the ʻōhiʻa trees.
