Oh sorry I guess I didn’t really expand on that. Part of why I like bird watching is that all (almost all) of the apps to identify birds are free. But then you have to actually be able to input parameters and stuff. So then you need to be able to pick out small details in a split second at a very long range. Even then, sometimes it’s not possible without help from others. So bird photography helps with the identification (and scientific study) of the birds.
