India’s first confirmed sighting of the Long-billed Bush Warbler in 46 years occurred on July 15, 2025, in Ladakh’s Suru Valley, detected by a distinctive insect-like call, prompting discussions on biodiversity conservation. The Near Threatened species was found in dense willow thickets above 3,200 meters, an altitude higher than typical for the bird, highlighting the potential ecological integrity of the Suru Valley’s habitats despite previous declines attributed to habitat destruction.
Key details
- Species: Long-billed Bush Warbler (Locustella major).
- Date: July 15, 2025.
- Location: Suru Valley, Ladakh, India.
- Altitude: Over 3,200 meters.

- Previous Sighting: The last confirmed sighting in India was in 1979.
- Team: A team of five birders, including Harish Thangaraj, Lt Gen Bhupesh Goyal, Manjula Desai, Rigzin Nubu, and Irfan Jeelani.
Ecological and Conservation Significance
- Biodiversity: The sighting renews interest in India’s biodiversity conservation and the search for “long lost birds”.
- Habitat Integrity: The presence of the warbler, a species reliant on undisturbed scrub habitats, indicates the potential ecological health of the Suru Valley’s wilderness.
- Habitat Loss: The species was previously common in the Suru Valley but declined due to habitat destruction and agricultural expansion, making the sighting significant for conservation efforts.
- Government Action: The ecological importance of this sighting was discussed in India’s Rajya Sabha, emphasizing the need for conservation.
PRACTICE QUESTIONS
Consider the following statements regarding the recent sighting of the Long-billed Bush Warbler in India:
I. The Long-billed Bush Warbler (Locustella major) was sighted in India after nearly five decades, detected by its unique insect-like song in Ladakh’s Suru Valley
II. The species, listed as Near Threatened (NT) by the IUCN, was found in dense willow thickets above 3,200 meters, an unusually high altitude, suggesting habitat shifts due to climate change
Which of the statements given above is/are correct?
a) I only
b) II only
c) Both I and II
d) Neither I nor II
Answer: c
Explanation: Statement I is correct: A team of birders confirmed the first sighting of the Long-billed Bush Warbler in India in 46 years (since 1979) in July 2025, in Ladakh’s Suru Valley, identified by its distinct “insect-like” call. Statement II is correct: The bird (IUCN: Near Threatened) was found in willow thickets at over 3,200 meters, higher than its usual range, pointing towards potential altitudinal shifts due to habitat pressures or climate change, as noted by experts.
