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 →

With luck
About 10% of wildlife watchers report a Jerdon's Baza sighting in Manas National Park on a given day, based on 130 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 158th most-seen of the 377 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.
March
In that month about 20% of wildlife watchers report a Jerdon's Baza in Manas National Park on a given day, against under 5% in August–October and December–January, the lowest months. That is one of Manas National Park's driest months, with about 100 mm of rain against 1070 mm in June.
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.
Among the best
Of the 14 parks where we can rate Jerdon's Baza sightings, Manas National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Kinabatangan Wildlife Sanctuary (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Jerdon's Baza is recorded against all the birds logged in Manas National Park (130 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.
