About World Curlew Day

World Curlew Day is observed on April 21 as an international awareness and conservation day for curlews.

Curlew Action, founded by Mary Colwell, currently coordinates World Curlew Day activities and educational material.

Why World Curlew Day matters

The day gives conservation groups, communities and the public a shared date to learn about curlew species, habitat pressures and conservation work.

Participation should respect wildlife law, nesting sites, land access rules and qualified conservation guidance, especially around breeding birds.

History of World Curlew Day

Curlew Action’s current World Curlew Day page says Mary Colwell founded the day in 2017.

Curlew Action explains that April 21 is St Beuno’s feast day and also the date Colwell began her 500-mile Curlew Walk in 2016.

A separate Curlew Action first-party history says World Curlew Day “got going” in 2018, so this guide does not force a single first-event year where the organizer’s own wording differs.

Curlew Action continues to run annual World Curlew Day events, competitions and campaigns, including in 2026.

Reader questions

Frequently asked questions

When is World Curlew Day?

21 April The documented recurrence rule is: 21 April.

Does World Curlew Day fall on the same date every year?

Yes. It uses a fixed annual date unless stronger evidence changes the pattern.

Is World Curlew Day an official public holiday?

The reviewed sources verify it within this scope: international curlew conservation awareness observance coordinated by Curlew Action. That recognition does not by itself make it a statutory public holiday; the site only makes public-holiday claims when reliable evidence explicitly does so.

Who established or recognizes World Curlew Day?

The documented basis is: Curlew Action verifies April 21, Mary Colwell’s origin role, explicit date rationale and continuing annual stewardship; because first-party pages use 2017 founding language and 2018 “got going” language, the exact first public observance year remains unresolved. Supporting evidence includes Curlew Action — World Curlew Day. The site does not infer a separate creator or founder unless reviewed evidence establishes one.

Is World Curlew Day international or country-specific?

The documented scope is international or global: international curlew conservation awareness observance coordinated by Curlew Action. That does not mean every country treats the date as a public holiday or observes it in the same way.
