Greater London Challenge 2025

🐦 Log 30 species

Join the Greater London Challenge 2025, enhance your birding skills, and contribute to urban wildlife research while exploring the enchanting beauty of London's avian residents. The variety of bird species found in London is a testament to the city's vibrant urban biodiversity and green spaces. Set a personal goal to spot and log 30 bird species in the Greater London area (inside the M25) by the end of the year!

This challenge is for anyone with a Birda account. This challenge is for tickable species only. You can read more about tickable species here.

This challenge starts and ends based on the UK time zone. All individual species logged within the M25 will count towards this challenge and will be included in any leaderboard placement. All sightings must be logged before midnight on the day the challenge ends.

Be honest with yourself and other birders, but above all, respectful of them and any other outdoor users, everywhere – especially online. If you didn’t see it (or hear it), please don’t put it on Birda.
