Cacomantis flabelliformis meeki (Rothschild & Hartert, 1902) – Solomon Islands including Santa Isabel, Kolombangara, Guadalcanal and Bellona. Originally designated Cacomantis meeki. Cacomantis flabelliformis pyrrhophanus (Vieillot, 1817) – New Caledonia including the Loyalty Islands.
Cacomantis flabelliformis schistaceigularis (Sharpe, 1900) – Vanuatu. Cacomantis flabelliformis simus (Peale, 1848) – Fiji. The fan-tailed cuckoo is about 25–27 cm (9.8–10.6 in) long.

Rare
Under 5% of wildlife watchers report a Fan-tailed Cuckoo sighting in Flinders Ranges National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 75th most-seen of the 94 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Fan-tailed Cuckoo in Flinders Ranges National Park on a given day, against under 5% in January–July and October, the lowest months. December has too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Fan-tailed Cuckoo sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
14th of 17
Of the 17 parks where we can rate Fan-tailed Cuckoo sightings, Flinders Ranges National Park ranks 14th at under 5%. The best odds are in Maria Island National Park (Australia, about 40%), Lamington National Park (Australia, about 30%) and Great Otway National Park (Australia, about 20%).
Same family: Cuculidae
The closest relatives of the Fan-tailed Cuckoo that you can see in Flinders Ranges National Park (family Cuculidae, Cuckoos) are Horsfield's Bronze Cuckoo (about 10%) and Black-Eared Cuckoo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Fan-tailed Cuckoo is recorded against all the birds logged in Flinders Ranges National Park (11 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.
