Whether you're a casual backyard birder, a serious life-lister, or a citizen scientist contributing to migration counts and bird population surveys, accurate species tallies matter. Paper notebook tally marks work but slow you down and risk damage in the field. A free digital tally counter solves both problems — and this guide walks through how birders are using Tally Counter App for their outings.
Setting Up Counters Before You Head Out
Open Tally Counter App in your phone's browser. Add one counter per species you reasonably expect to see during the outing. Label each with the common name (or scientific name if you prefer):
- Northern Cardinal
- Blue Jay
- American Robin
- House Sparrow
- Mourning Dove
- Red-tailed Hawk
- ... and so on for your likely species
Switch to Grid view to see all counters at once. Keep the screen open during your outing; counts save automatically even if the screen sleeps.
During the Outing
When you observe a bird, tap the appropriate counter. The count updates instantly. If you observe a species you didn't pre-register, tap "Add Counter" and add it on the spot — takes about 5 seconds. For rapid succession sightings (e.g., a flock of robins arriving), you can tap repeatedly without delay.
If you over-tap by accident (saw 4 cardinals but tapped 5), hit the undo button to back off the last tap.
Why It Works Better Than a Notebook
- Faster to update than handwriting. Tap = ~0.2 seconds. Writing a tally mark and finding the right row = ~3-5 seconds. For high-volume sightings, this matters.
- Works in rain. A waterproof phone case or a Ziploc bag keeps your phone counting. Notebooks turn to mush.
- Persistent through phone sleep. Counts save automatically. Wake the phone hours later — counts are exactly where you left them.
- Full-screen mode for outdoor visibility. Large numbers visible in bright sun.
- Free. No $30 specialized birding counter required.
Specific Birding Scenarios
Big Year / Big Day counts
For Big Year (every species seen in a calendar year) or Big Day (every species seen in 24 hours), maintain a master counter set across the entire period. Sync via free account so the same counter set is available on phone, tablet, and laptop. Reset only when the period ends.
Hawk watch / migration counts
Hawk watches involve counting raptors over multi-hour periods, often hundreds per species. Set up a counter for each raptor species (Broad-winged Hawk, Sharp-shinned Hawk, Cooper's Hawk, etc.). Tap as each bird is identified. End-of-watch totals feed directly into HawkCount or NEHW databases.
Backyard FeederWatch (Project FeederWatch by Cornell)
FeederWatch asks for maximum simultaneous counts of each species. Use the tally counter to record each unique sighting; the count gives you a conservative estimate of total visits, which you can compare against the field of view at any moment for a max-simultaneous estimate.
Wetland or shorebird surveys
Counter per species (Sanderling, Dunlin, Willet, etc.) for shorebird flocks. The Grid view lets you tap rapidly as you scan through scope views. Some birders use Dual view for high-volume two-species counts (Sanderling vs Western Sandpiper, for example).
End of Outing: Transcribing to eBird
When you finish the outing, screenshot the Grid view (or the List view if you have many counters). The screenshot gives you a complete species + count snapshot. Transcribe these into your eBird checklist on the eBird mobile app or website. The whole transcription takes 2-3 minutes for a typical 10-species outing.
Direct eBird/iNaturalist export from the tally counter is planned for late 2026.
Pro Tips From Field Researchers
- Pre-populate species lists for known sites. If you regularly visit the same wetland, set up the counter set once and just reset values each visit. Saves 5-10 minutes of setup time.
- Use vibration feedback for eyes-on-bins counting. Enable vibration in settings; you'll feel each tap registered without taking your eyes off your binoculars.
- Phone in jacket pocket with screen on. Many birders count blind by feel, then verify totals at end of outing.
- Battery saver mode is your friend for long outings. The app is lightweight — battery saver won't affect counting.
- Multiple birders, one shared set. Real-time multi-user sharing is in development for late 2026. For now, one designated counter per group works well.
Get Started
Open Tally Counter App on your phone before your next outing. Set up counters for your expected species. Tap as you see each bird. End-of-outing totals are ready to transcribe to eBird in minutes.
