CORNELL LAB OF ORNITHOLOGY
This year, the Cornell's bird lab's centennial year, they're inviting everyone around the globe who loves birds to be a part of the Global Big Day team. Their goal is to raise $500,000 for conservation and, with help from birds everywhere, collectively tally 4,000 of the world's 10,300 bird species in a single day. This is the real deal for conservation and birding.
