The Spot-bellied Eagle Owl Ketupa nipalensis,
also known as the Forest Eagle Owl, is a large species of owl found in parts of
southern and southeastern Asia (König & Weick 2008). The Spot-bellied Eagle
Owl has a disjunct distribution in India, primarily inhabiting well-forested
areas in hilly or mountainous regions. Its range includes the sub-Himalayan
belt from Uttarakhand eastward through northeastern India, the Western Ghats
from southwestern Maharashtra to its southern tip, and locally in the Eastern
Ghats, central Indian highlands, and parts of Gujarat (Jayapal
et al. 2005; Grimmett et al. 2011; Majumder et al. 2011; Rasmussen & Anderton
2012). The species is categorized as ‘Least Concern’ under the IUCN Red List
due to its large range, although its population trend is decreasing (Birdlife
International 2018).
On 27 September 2024, at
approximately 2130 h, an individual of Spot-bellied Eagle Owl was observed and
photographed perching on a Ficus religiosa tree (Image 1) in the mixed deciduous forests
of the South Division, within the Palamau Tiger
Reserve, Jharkhand (23.5990 N, 84.1530 E). It was sighted
on a clear night with a temperature of approximately 24 oC.
The individual was identified as a Spot-bellied Eagle Owl by its large size
(60–70 cm), prominent ear tufts, and characteristic spotting on the underparts,
which were clearly visible even in the low light conditions (Grimmett et al. 2011). The deep, booming call often heard
at dusk and dawn further confirmed our suspicions (Ali & Ripley 1981).
These features distinguish it from other owl species found in the region, such
as the Brown Fish Owl Ketupa zeylonensis or the Indian Eagle Owl Bubo bengalensis.
The nearest known populations are
in the Central Indian highlands, though specific recent records from this
region are scarce. The closest documented recent sighting is from Similipal Tiger Reserve, Odisha, approximately 400 km
south-east, where the first photographic record for the state was obtained in
2018 (Nayak et al. 2019). Additionally, individuals of this species were
observed at Satkosia Tiger Reserve, perched on a Shorea robusta
tree, and at Tamana Reserve Forest roosting on a Terminalia
bellirica tree (Jena et al. 2025). Recent eBird records have documented the species from several
locations in Odisha: Labangi Forest Road, Angul (Nair 2023), Bhajam-Champagarh
Forest Road, Mayurbhanj (Rathore 2020), Rissia, Kuldiha, and Baleswar (Chand
2024), all within 250–350 km south-east of our observation. Further north-east,
the species has been consistently recorded from northern West Bengal, including
Buxa Tiger Reserve (Shome
2018), Mahananda Wildlife Sanctuary, and Rongtong,
Darjeeling (Mehta 2024; Roy 2024), approximately 450–550 km from the present
location. Several records indicate the presence of the Spot-bellied Eagle Owl
in central India. Notably, photographic evidence exists from Kanha National Park, Madhya Pradesh, with sightings
reported in February 1994 (D’Cunha & Ali 2001) and May 2007 (Deshmukh
2008). Additional records include observations from Bori
Wildlife Sanctuary (Mehta 1998; Jayapal et al. 2005)
and Pench Tiger Reserve, where an individual was
documented in April 2004 (Jayapal et al. 2005) and again
in March 2011 (Majumder et al. 2011). Another notable record comes from Papikonda National Park, Andhra Pradesh, roughly 700 km
south, which represented a range extension in the Eastern Ghats (Srinivasan
2013). The observation in Palamau Tiger Reserve extends
the known distribution of the Spot-bellied Eagle Owl significantly westward
within central India, suggesting a broader but underreported presence in this
region. This sighting is particularly noteworthy given the species’ association
with specific habitat types and its generally patchy distribution.
Several hypotheses could explain
this unusual sighting, as intercontinental vagrants are even seen due to
climatic changes (Byju & Raveendran 2022): (1)
Range Expansion: Climate change and habitat alterations might be driving the
species to expand its range. (2) Undocumented Population: A small, previously
unrecorded population might exist in or around Palamau
Tiger Reserve. (3) Vagrant Individual: The observed owl could be a vagrant that
has strayed far from its typical range. (4) Seasonal Movement: Although not
known for long-distance migrations, this sighting could indicate previously
unknown seasonal movements.
This observation underscores the
need for comprehensive avifaunal surveys within Palamau
Tiger Reserve and surrounding areas. Such surveys could reveal whether this
sighting represents an isolated incident or indicates a broader shift in the
species’ distribution. The documentation of the Spot-bellied Eagle Owl in Palamau Tiger Reserve highlights the potential for
discoveries even in relatively well-studied areas and emphasizes the importance
of continued biodiversity monitoring in protected areas.
