Jerdon's baza (Aviceda jerdoni) is a moderate sized brown hawk with a thin white-tipped black crest usually held erect. It is found in South-east Asia. It inhabits foothills in the terai and is rarer in evergreen forests and tea estates.
The common name and Latin binomial commemorate the surgeon-naturalist Thomas C. Jerdon. It is about 41–48 cm long with a wingspan of 117 cm (46 in). The bird weighs around 350 grams (.77 lb). It is confusable with crested goshawk or the changeable hawk-eagle in flight, but can be distinguished by the longer upright crest, very broad and rounded paddle-shaped wings and mostly plain and pale underparts. It has a white chin and a bold black mesial stripe.
Several subspecies are recognized within its large distribution range. These include: It is a resident of the terai of North India and foothills of the Eastern Himalayas... Wikipedia →

Rare
Under 5% of wildlife watchers report a Jerdon's Baza sighting in Singapore on a given day, based on 309 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 298 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Jerdon's Baza in Singapore on a given day, against under 5% in December to October, the lowest months. That is one of Singapore's wettest months, with about 280 mm of rain against 100 mm in February.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Jerdon's Baza sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Jerdon's Baza sightings, Singapore has the highest daily chance: under 5%. Next come Phnom Penh (Cambodia, under 5%).
GBIF citizen-science records
It is estimated from how often the Jerdon's Baza is recorded against all the birds logged in Singapore (309 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.
