The orange-fronted fruit doves are members of the genus Ptilinopus in the family Columbidae.[2] Birds of this genus are typified by small to medium-sized bodies and vibrant plumage.[2] The specific epithet aurantiifrons is derived from Latin aurantius, meaning 'orange' and frons, meaning 'front' or 'forehead'.[3]

Ecology and behavior
Voice
P. aurantiifrons vocalizations are described as a medium to low pitch of “hoo” followed by a seesaw (a series of alternative high and low notes).[4] Each note of the “hoo” rises in tone.[1] The seesaw pattern features six notes with the first, third, and fifth rising in pitch while the other notes descend.[1] Additionally, P. aurantiifrons produce a sequence beginning with a single low note, followed by a louder series that gradually decreases in pitch.[1]
Feeding
P. aurantiifrons is observed in flocks, but also forages alone or in pairs.[1] The orange-fronted fruit dove is frugivorous, consuming fruits from various plant types.[1] Moraceae (mulberry family), Combretaceae (white mangrove family), and Arecaceae (palm family) are included in the primary diet of P. aurantiifrons.[1]
Breeding
Nesting takes place from the middle of the dry season to at least the early wet season; the breeding season is from September to April.[1] The nest is sturdier than those typical of the genus and is positioned at a height of 2.4 to 4.6 meters in trees or shrubs.[1] P. aurantiifrons lays a single white egg and does not incubate tightly.[1]
Distribution and habitat
The Orange-fronted fruit doves are found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, woodland, savanna and urban areas.[1] It is abundant along the eastern coast of New Guinea and the D’Entrecasteaux islands.[1]
Threats and protection
Conservation details of this species are limited. The orange-fronted fruit dove is not considered globally threatened and is classified as Least Concern.[1] P. aurantiifrons are regarded as common and abundant locally.[1]
