The Sri Lanka drongo (Dicrurus lophorinus) or Ceylon crested drongo, is a species of bird in the family Dicruridae. It is endemic to Sri Lanka. It was previously considered a subspecies of the greater racket-tailed drongo. Its natural habitats are subtropical or tropical moist lowland and montane forests.
Dicrurus lophorinus Vieillot, 1817, has in the past been placed in monospecific Dissemurulus, or in Dissemuroides. May form a super species with D. paradiseus, often treated as conspecific, but differs in tail morphology and probably in voice. Molecular-genetic studies required in order to elucidate taxonomic status. Few inter grades with race ceylonicus of D. paradises formerly reported along border between wet and dry zones, but interbreeding not now possible, since suitable habitat no longer remains between the two ecological zones, now completely separated.
The species can be found throughout Wet zone of South Western parts of Sri Lanka, from Deduru Oya to Walawe. The Sri Lanka drongo has black plumage with a metallic blue or greenish-blue sheen. It has an arching, helmet-like crest, red eyes, and a deeply-forked tail. Both... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sri Lanka Drongo sighting in Colombo [Sri Jayawardenepura Kotte] on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 187th most-seen of the 204 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sri Lanka Drongo in Colombo [Sri Jayawardenepura Kotte] on a given day, so our monthly data shows no clear season.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Sri Lanka Drongo sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Colombo [Sri Jayawardenepura Kotte], in our data
Colombo [Sri Jayawardenepura Kotte] is the only city on Wallace's Line with enough records to rate Sri Lanka Drongo sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sri Lanka Drongo is recorded against all the birds logged in Colombo [Sri Jayawardenepura Kotte] (9 verified sightings), 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.
