When you sign up for a free eBird account it is somewhere in the fine print
that any images you upload are used in The Macaulay Library. With the amount of photos uploaded anyone that finds one in a species description has done well due the the shear volume uploaded.
1. It creates a permanent home for documentation associated with eBird records at the Macaulay Library.
2. It allows eBird, the Cornell Lab, and its global partners to engage emerging communities of nature enthusiasts.
3. It enables eBirders to become a richer source of real-time information and knowledge about birds in our world.
