May eBirder of the Month Challenge

By Team eBird April 30, 2023

This month’s eBirder of the Month challenge, sponsored by Carl Zeiss Sports Optics, is all about birding on Global Big Day! The eBirder of the month will be drawn from eBirders who submit five (5) or more eligible checklists on 13 May. Last year, eBirders in 201 countries found an astonishing 7,673 species in a single day. What can we achieve together this year?

We’re excited to announce a special prize for the May eBirder of the Month challenge: the ZEISS SFL 30—the newest, lightest and most compact binoculars to the ZEISS SF family. The ZEISS SFL (SmartFocus and Lightweight) stands out for its exceptional optical performance combined with an extremely compact design and low weight. The new ZEISS SFL 30 binoculars are extremely compact and therefore conveniently fit in a bag, backpack, or jacket pocket.

Be a part of the world’s biggest day of birding and celebrate World Migratory Bird Day simply by submitting eBird checklists on 13 May. It doesn’t matter where you are or how many species you see—every eBird checklist submitted on May 13 counts towards the Global Big Day results. Of course, if you want a chance to win the new ZEISS SFL 30 binoculars, submit at least five eligible checklists!

May’s winner will be notified by the 10th of the following month. Each month we will feature a new eBird challenge and set of selection criteria. And don’t forget to submit lists for the 2023 Checklist-a-day Challenge!
