The common iora (Aegithina tiphia) is a small passerine bird found across the tropical Indian subcontinent and Southeast Asia, with populations showing plumage variations, some of which are designated as subspecies. A species found in scrub and forest, it is easily detected from its loud whistles and the bright colours. During the breeding season, males display by fluffing up their feathers and spiral in the air appearing like a green, black, yellow, and white ball.
In 1747 the English naturalist George Edwards included an illustration and a description of the common iora in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Green Indian Fly-Catcher". Edwards based his hand-coloured etching on a specimen that had been sent from Bengal to the silk-pattern designer and naturalist Joseph Dandridge in London. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the common iora in the genus Motacilla. Linnaeus included a brief description, coined the binomial name Motacilla tiphia and cited Edwards' work. The common iora is now placed in the genus Aegithina that was introduced... Wikipedia →

With luck
About 10% of wildlife watchers report a Common Iora sighting in Chattogram on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 55th most-seen of the 76 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
January and September
In those months about 20% of wildlife watchers report a Common Iora in Chattogram on a given day, against under 5% in October, the lowest month. April and July–August have too few records to rate.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Common Iora sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
38th of 63
Of the 63 cities where we can rate Common Iora sightings, Chattogram ranks 38th at about 10%. The best odds are in Savar (Bangladesh, about 60%), Solapur (India, about 50%) and Yogyakarta (Indonesia, about 50%).
Same order: Passeriformes
The closest relatives of the Common Iora that you can see in Chattogram (order Passeriformes, Perching Birds) are Indian Pied Starling (about 80%), House Crow (about 70%) and Striated Grassbird (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Iora is recorded against all the birds logged in Chattogram (6 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.
