Log every bird you see in the wild and watch its collectible card flip into your deck. Five rarity tiers, holographic foils on the rarest finds, and your life list growing with every walk.
No quizzes, no grinding. Just look up, notice a bird, and let your collection grow with every walk.
Out on a walk or watching the feeder, you see a bird. Hit “Spot a bird” and tell TwitcherDeck what you saw.
We match it against the field guide — plumage, size, song, habitat — and confirm the species in seconds.
Its card flips into your deck. The rarer the bird, the bolder the border and the shinier the foil.
Every species sits on a five-tier rarity scale. The harder it is to spot in the wild, the more spectacular its card.
Rare and up get an animated rainbow sheen that catches the light as you tilt the card.
No packs to buy. The only way a card joins your deck is to genuinely spot the bird.
No paywalls and no premium tiers — spotting and collecting are free for everyone, always. Fancy supporting the project? Each donation enters you into the monthly prize raffle.
Chip in whatever you like, whenever you like. Every penny goes straight into keeping TwitcherDeck free for everyone.
Each donation earns you entries into the current month’s prize raffle — give a little more, get a few more chances.
At the end of every month we draw winners at random. Birding kit, rare prints and seasonal surprises up for grabs.
Completely. Every feature and every species is free for everyone, forever. TwitcherDeck is funded by optional donations — not paywalls or premium tiers.
Donate any amount and you're entered into that month's prize raffle — roughly one entry per pound. We draw winners at random at the end of every month.
Never. Donations are entirely optional and only affect the raffle — they don't unlock anything. The whole of TwitcherDeck is identical for everyone.
Birding kit, rare bird prints and seasonal surprises. The prize pot grows with the community, so the more support comes in, the better the draws get.
Nope. TwitcherDeck runs on the honour system of every good birder's log — you tell us what you spotted and we add the card. Snapping a photo is optional.
Not at all. TwitcherDeck lives on the web — open it in any browser on your phone or laptop and your deck is right there. Nothing to install.
All of TwitcherDeck, free forever. Spot your first bird and watch its card flip into your collection in the next five minutes.
