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 Khao Yai National Park on a given day, based on 111 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 151st most-seen of the 278 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February and November–December
In those months about 10% of wildlife watchers report a Jerdon's Baza in Khao Yai National Park on a given day, against under 5% in January and March–October, the lowest months. Those are among Khao Yai National Park's driest months, with about 40 mm of rain a month against 330 mm in September.
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, Khao Yai National Park ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Kinabatangan Wildlife Sanctuary (Malaysia, about 10%), Manas National Park (India, about 10%) and Kaeng Krachan National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Jerdon's Baza is recorded against all the birds logged in Khao Yai National Park (111 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.
