World Migratory Bird Day

A global campaign, held on two days a year to match the spring and autumn migration peaks, to raise awareness of migratory birds and the threats they face. The 2026 theme is "Every Bird Counts – Your Observations Matter!".

It is organised by CMS, AEWA, EAAFP and Environment for the Americas. Birbs is not involved in running it — the details below are taken from the organiser's own site, which has the final word.

When is the next World Migratory Bird Day?

The next dates have not been announced by CMS, AEWA, EAAFP and Environment for the Americas yet. Two days a year: the second Saturday of May (Canada and the US) and the second Saturday of October (Mexico, Central and South America and the Caribbean), per Environment for the Americas; events can be held on any day.

The last World Migratory Bird Day was held on 10 October 2026.

How to take part

1. Join or host a local World Migratory Bird Day event, walk or school activity.
2. Go out and record the migrants you see — the 2026 theme invites everyone to share their observations.
