MerlinVision Help train Merlin® to identify birds.

Photo ID in the free Merlin app can already identify 1,700+ species of birds. You can draw boxes and help us expand the list!

Choose a project:

Single Boxes

Teach MerlinVision to identify more species, and improve accuracy, by drawing a box around a single bird of the target species in each photo.
