Celebrating World Sparrow Day 2025 on March 20
Every year on March 20, World Sparrow Day is celebrated to highlight the vital role sparrows play in maintaining biodiversity and ecological balance.
In Sri Lanka, house sparrows, known as (ගේ කුරුල්ලා in Sinhala, Scientific name: Passer domesticus), were an inseparable part of my childhood. I can still picture those small clay pots that hung from the walls or roof timbers of our houses, each with a tiny hole in the middle. Watching sparrows flutter in and out, building their nests, and raising their little families was such a simple yet heartwarming sight. It’s heartbreaking to think that their numbers have dwindled over the years.

Sparrows, especially the common house sparrow, have been humanity's feathery companions for centuries, evolving alongside us and becoming one of the most widespread bird species. They do so much for our ecosystems—they gobble up seeds and spread them across the land, promoting plant growth and helping vegetation thrive. And yet, despite being such hardy little birds, their populations are fading. This decline—seen in urban and rural areas alike—is a stark reminder of how much our environment is changing and how these shifts could ultimately affect our well-being too.
Once the most common bird in the world, house sparrows now face threats like habitat loss, urban sprawl, modern agricultural practices, and declining insect populations. They’ve lost many of their nesting and feeding grounds. Their absence can ripple through ecosystems, leading to biodiversity challenges and even an uptick in pest problems. Efforts like urban greening and agroecological practices are steps in the right direction to create spaces where sparrows—and we—can thrive together.
World Sparrow Day, launched in 2010 by the Nature Forever Society, is a call to action. It's a global platform to shed light on the conservation of sparrows and the habitats they need. It aims to rally individuals, groups, scientists, and governments to join forces in safeguarding these little creatures. Together, we can encourage meaningful change.
In Europe, house sparrow populations have declined drastically in places like the Czech Republic, where millions have vanished over recent decades. Urban modernization, agricultural intensification, and changes in greenery have taken a heavy toll. House sparrows, often seen near human settlements, have distinct features: males flaunt dark brown wings, a gray head, and a black bib, while females are a softer shade of brown. Their relatives, tree sparrows, prefer agricultural areas and can be identified by their chestnut-brown head and the black spot on their white cheeks.
World Sparrow Day isn’t just about celebrating sparrows for a day; it’s about preserving urban biodiversity and drawing attention to conservation needs. It’s about cherishing those simple, cherished memories of their chirps and rustling wings, while working together to ensure they have a place in the future too. Let’s hope to keep hearing their cheerful songs for many years to come.
