What I Learned in Costa Rica from October Global Big Day, 2021
10,000 Birds
OCTOBER 16, 2021
Similar to 2020, more than 32,000 people participated, 78,000 checklists were submitted, and more than 7,200 bird species were identified. Another October Big Day has come and gone and thus made its way into the sacred birding archives. Nothing like getting as many people to bird at the same time as possible and see what they find!
