The species was described by Jean Cabanis in 1882. It is monotypic. The specific epithet mechowi honours Friedrich Wilhelm Alexander von Mechow, a Prussian explorer. The name occidentalis for a population with different songs is a nomen nudum.

Possible
About 20% of wildlife watchers report a Dusky Long-tailed Cuckoo sighting in Bwindi Impenetrable National Park on a given day, based on 330 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 92nd most-seen of the 400 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Dusky Long-tailed Cuckoo in Bwindi Impenetrable National Park on a given day, against under 5% in October, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dusky Long-tailed Cuckoo sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Dusky Long-tailed Cuckoo sightings, Bwindi Impenetrable National Park ranks 3rd at about 20%. The best odds are in Semuliki National Park (Uganda, about 30%) and Kibale National Park (Uganda, about 20%).
GBIF citizen-science records
It is estimated from how often the Dusky Long-tailed Cuckoo is recorded against all the birds logged in Bwindi Impenetrable National Park (330 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.
