From the Cornell Lab of Ornithology in the USA:
May 14, 2016. The second Global Big Day. We need your help to make it the biggest day of birding the world has ever seen. With less than three months until the day, it’s time to get started!
Last year, thanks to participation from eBirders worldwide, we were able to engage more than 14,000 people in 135 countries to submit almost 45,000 checklists, featuring 6,085 species of birds. All in a single day. More importantly, it introduced eBird to hundreds of new people, resulting in thousands of valuable checklists of bird sightings that are used for science and conservation worldwide. Thank you to all who participated, and we look forward to seeing many new faces joining the ranks this year!
If you could get two friends excited about the Global Big Day and each of those people help with spreading the word, imagine how many people would take part! We really hope that you’ll take this as a great opportunity to unite the entire birding community behind a shared cause: how many birds can we find in a single day? 2015 GBD outreach had just one month of lead time, and much of this information came too late for it to be as useful as possible for our passionate users like you. This year we are starting early!
