Dicrurus balicassius
In 3 days <5%
The balicassiao (Dicrurus balicassius) is a species of passerine bird in the family Dicruridae. It is endemic to the Philippines. Its natural habitat is tropical moist lowland forests. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the balicassiao in his Ornithologie based on a specimen collected in the Philippines. He used the French name Le choucas des Philippines and the Latin Monedula Philippensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the balicassiao. Linnaeus included a brief description, coined the binomial name Corvus balicassius and cited Brisson's work. The specific name balicassius is from Balicasiao, the Cebuano word for this bird. This species is now placed in the genus Dicrurus that was introduced by French ornithologist Louis Pierre Vieillot in 1816.

Rare
Under 5% of wildlife watchers report a Balicassiao sighting in Manila on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 163rd most-seen of the 191 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 Balicassiao in Manila on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Balicassiao sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manila, in our data
Manila is the only city on Wallace's Line with enough records to rate Balicassiao sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Balicassiao is recorded against all the birds logged in Manila (21 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.
