Alkas vs. Field Guides
Field guides are essential references. But looking something up once doesn't mean you'll remember it. Here's why active recall matters.
Reading doesn't equal remembering
You see an unfamiliar bird. You pull out your Sibley guide, flip to the warbler section, and find it: Bay-breasted Warbler. You read the description, note the field marks, and put the book away. Two weeks later, you see the same bird. Nothing. The name is gone.
This isn't a failure of effort - it's a well-documented feature of human memory. Psychologists call it the "forgetting curve." Within a week, you lose roughly 90% of what you learned through passive reading. Field guides are optimized for looking things up, not for building lasting recognition.
The fix isn't to read harder. It's to use a different learning technique altogether.
Two techniques that actually work
Active recall
Instead of reading a name and nodding, you look at a photo and try to retrieve the answer from memory. This effort of retrieval strengthens the neural pathway far more than passive recognition.
Research consistently shows that testing yourself is 2-3x more effective than rereading the same material.
Spaced repetition
Instead of cramming, you review each species at increasing intervals - right before you'd forget it. The timing matters: reviewing too early wastes time, too late and you've already forgotten.
This is the same system medical students use to memorize thousands of terms. It works because it aligns with how memory naturally consolidates.
What Alkas adds to your learning
Scheduled review
The algorithm tracks every species you've studied and schedules reviews at the perfect time. You don't have to decide what to study - just open the app.
Community-voted photos
Field guide illustrations show one angle. Alkas shows photos from the community - users upload their own and vote to surface the best ones for identification. Multiple angles, seasons, and lighting conditions.
Decks as specific as your curiosity
A field guide covers an entire continent. Alkas lets you build a deck for migratory shorebirds of the Maritimes or tiny hummingbirds of British Columbia - using region, season, and community-voted traits as filters.
Progress tracking
See which species you've mastered, which ones trip you up, and how your knowledge grows over time. A field guide can't tell you what you've forgotten.
Alkas doesn't replace your field guide
Field guides are still the best tool for identifying an unknown species in the moment. Range maps, detailed illustrations, behavioral notes - nothing beats a good guide when you're standing in the field trying to figure out what you're looking at.
But a field guide can't make you remember what you looked up. Alkas fills that gap. Use your guide to identify. Use Alkas to remember. Over time, you'll need the guide less and less because the species are already in your memory.
Already tracking observations on eBird or iNaturalist? Import your life list into Alkas and study the species you've looked up but can't yet recognize on your own.
Reading isn't remembering
"I was hoping for some type of app I could use to study. Ideally, I could put in my region and start with the most common birds and just flip through cards - picture, call. Not a record-and-identify application, but an educational, learn the calls, study application."
"I am hoping to find an app that teaches me about birds, like if I had flash cards or something. Not an app that relies on me finding and identifying them first."
"I'm looking for something that would show me a pic of the bird, and then I have to look up what it is to identify it. Literally just a random scrambling of images."
"Is there a learning app you'd recommend? One that's more Duolingo than field guide. Show me a picture and some choices of birds and I'll learn through repetition."
"It would be great if I could select My List as if it were a state, and then simply swipe through the list, working on learning field marks, calls, etc."
Remember what you look up
Your field guide teaches you once. Alkas helps you remember forever. Free.
