Help train Merlin® to identify birds in the Macaulay Library archive.

Our Photo ID tools are able to identify 650+ species of North American birds, and our goal is to improve the accuracy and number of species Merlin can identify. Once Merlin's engine is fully trained, we'll use it to verify the identification of birds in images submitted via eBird to the Macaulay Library.

Get Started
