Alkas vs. BirdWise
Both help you learn species identification. They take very different approaches. Here's how to decide which fits you.
The short version
BirdWise is Cornell Lab's bird identification trainer. It uses adaptive quizzing to test your bird knowledge, adjusting difficulty as you improve. It's well-designed and backed by a respected institution - but it only covers birds.
Alkas uses spaced repetition - a different and more effective learning technique - and covers all wildlife: birds, mammals, insects, plants, fungi, and reptiles. The community uploads photos and votes on them to surface the best ones for learning. They add traits to species and vote on those too, so your flashcards always show the most useful identification details. Plus: custom decks for any region or park, life list integration, and trip preparation tools.
Adaptive quizzing vs. spaced repetition
BirdWise: Adaptive quizzing
Presents questions and adjusts difficulty based on your answers. Harder species appear more often. Good for testing what you know, but doesn't schedule reviews at the optimal time for long-term memory.
Alkas: Spaced repetition
Schedules each species review at the precise moment before you'd forget it. Cards you struggle with appear more often. Cards you know well space out to weeks, then months. This is the same technique medical students use to memorize thousands of terms - it's proven to build lasting memory.

Decks as specific as your curiosity
BirdWise offers pre-set quizzes. You can't study carnivorous plants of Ontario, or giant mammals of Banff, or colorful butterflies of your province - because it only covers birds, and you can't combine filters like that.
In Alkas, deck creation is the core experience. Pick a region or park, filter by wildlife group and season, add community traits as filters, and you have a ready-to-study deck in seconds. The community adds traits like "carnivorous," "giant," or "colorful" to species - and you can use any of them to build decks that match exactly what you want to learn.
Bring your existing data
BirdWise is a standalone app - there's no way to connect your existing birding data. Alkas integrates with the tools you already use. Connect your iNaturalist account to import species you've observed, or upload your life list from eBird (includes Merlin data) or Audubon Bird Guide. Your birding history becomes the foundation for targeted study.
Community-powered content
BirdWise is a closed system - the content is what Cornell provides. In Alkas, the community makes the content better every day. Users upload their own photos and the community votes to surface the best and most useful ones for identification. Users add traits to species - like "chestnut flanks," "insectivore," or "boreal forests" - and vote on those too.
Your flashcards show the most helpful photos and the most relevant identification traits, curated by other naturalists who are learning alongside you.
When BirdWise is better
- - You only study birds and don't need other wildlife groups
- - You prefer a quizzing format over flashcard-style study
- - Cornell Lab's brand and backing matter to you
When Alkas is better
- + You want to learn more than just birds
- + You want proven spaced repetition scheduling for lasting memory
- + You want custom decks for your region, park, or upcoming trip
- + You want to import data from iNaturalist, eBird, Merlin, or Audubon
- + You want community-voted photos and traits you can use to build decks
- + You want a free tool
