At Rajasthan's Keoladeo Ghana National Park in Bharatpur, birdwatchers are relying on their ears more than their eyes this season. The rare and famously shy Bristled Grassbird has become active again in the park's grasslands with the arrival of the monsoon, and while its clear, melodic call is easy to catch, actually spotting the bird is another matter entirely.
A voice you can trace, a bird you rarely see
The Bristled Grassbird is known for exactly this contradiction: it is far easier to hear than to see. The bird lives deep inside tall, dense grass and bolts for cover the moment it senses a human nearby. That is why visitors and birdwatchers who come to Keoladeo often pick up its loud, sweet call without ever laying eyes on the bird itself.
What the monsoon changes on the ground
The shift happens because monsoon rain transforms the park's landscape. Grass and reed cover, including the tall kans grass, grows thick and lush, giving birds both shelter and easy access to food. That fresh cover is what draws shy, grass dwelling species like the Bristled Grassbird out of hiding and into vocal activity, and it is also why the park's bird life visibly changes character from one season to the next.
Hours of patience for a single glimpse
The call is now being heard across several grassy stretches of the park, and it carries clearly enough that experienced birdwatchers can judge the bird's presence from a distance. Bird photographers have been spending hours stationed in the grasslands hoping to capture even a single frame of the bird. The catch is that any unnecessary movement or noise sends it straight back into the grass, so staying still and quiet is the only real strategy for a sighting.
A park built on biodiversity
Keoladeo Ghana National Park is recognised worldwide for its biodiversity and is home to hundreds of bird species. Bird activity and numbers here shift visibly with the seasons, and during the monsoon months the grasslands become a crucial, if temporary, habitat for several local and rare birds. The Bristled Grassbird's reappearance is one of the clearest examples of that seasonal change.
Visiting this monsoon? Keep your ears open
Anyone planning a monsoon visit to Keoladeo Ghana would do well to search for birds with their ears, not just their eyes. The Bristled Grassbird may stay hidden in the thick grass throughout the visit, but its melodious call is often the surest sign that it is right there.
