I don't know of a gamified version (but would love to see one), but for help identifying, validating, and tracking sightings you may find the Merlin app from TheCornellLab useful.
Oh, I definitely use and love the major apps. I was thinking more in terms of repetition and reward to aid memorization.
There are numerous birds i can identity by sight or sound rather easily, but... I still struggle with mixing many smaller finch sized birds; females and juveniles against similar colored males of another species; and how numerous calls sound very alike.
Having an app to drill and test me would be wonderful.
Seek is probably the closest to what you're describing, but it's not just for birds.
iNaturalist has a gamified element to it as well, but it's pretty barebones. It's basically just "These are popular things in your area that you haven't found yet" and when you find them, they just drop off the list silently.
This is a fantastic idea. It would have a limited audience, but I donβt know why duolingo doesnβt use their app for other gamified learning.
For instance, Iβd love some gamified learning around tying various knots. I donβt use knots for my job, but Iβve always felt like it would be handy to know 10-15 of the most common knots for when I go into the woods.
Limited audience indeed. It sure would be great to have all kinds of gamified learning content, though. Constant reenforcement and rewards helps a lot. Like my dog and treats. π€ͺ
