The crescent honeyeater (Phylidonyris pyrrhopterus) is a passerine bird of the honeyeater family Meliphagidae native to southeastern Australia. A member of the genus Phylidonyris, it is most closely related to the common New Holland honeyeater (P. novaehollandiae) and the white-cheeked honeyeater (P. niger). Two subspecies are recognized, with P. p. halmaturinus restricted in range to Kangaroo Island and the Mount Lofty Ranges in South Australia.
It has dark grey plumage and paler underparts, highlighted by yellow wing-patches and a broad, black crescent, outlined in white, down the sides of its breast. The species exhibits slight sexual dimorphism, with the female being duller in colour than the male. Juvenile birds are similar to the female, though the yellow wing-patches of male nestlings can be easily distinguished.
The male has a complex and variable song, which is heard throughout the year. It sings from an exposed perch, and during the breeding season performs song flights. The crescent honeyeater is found in areas of dense vegetation including sclerophyll forest and alpine habitats, as well as heathland, and parks and gardens, where its diet is made up of nectar and invertebrates. It forms long-term pairs, and often stays committed to one breeding site for several years. The female builds the nest and does most of the caring for the two to three young, which become independent within 40 days of laying its egg.
The parent birds use a range of anti-predator strategies, but nestlings can be taken by snakes, kookaburras, currawongs, or cats. While the crescent honeyeater faces a number of threats, its population numbers and distribution are sufficient for it to be listed as of Least Concern for conservation. Wikipedia →

Possible
About 20% of wildlife watchers report a Crescent Honeyeater sighting in Great Otway National Park on a given day, based on 770 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 45th most-seen of the 175 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April–June and August
In those months about 30% of wildlife watchers report a Crescent Honeyeater in Great Otway National Park on a given day, against about 10% in December, the lowest month.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Crescent Honeyeater sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 9
Of the 9 parks where we can rate Crescent Honeyeater sightings, Great Otway National Park ranks 5th at about 20%. The best odds are in Cradle Mountain-Lake St Clair National Park (Australia, about 80%), Wilsons Promontory National Park (Australia, about 50%) and Flinders Chase (Australia, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Crescent Honeyeater is recorded against all the birds logged in Great Otway National Park (770 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
