WhatDatBird

WhatDatBird is a bird identification quiz that works anywhere in the world. Pick a location on the map — or tap the crosshair to quiz where you stand — and it generates questions from live GBIF/iNaturalist data. Distractors come from the nearest related species, with four difficulty levels and an audio mode for call-based quizzes.

Wikipedia identification tips and a local leaderboard round it out. The author says it was "Built entirely with Claude Code." The project was pushed two days before this listing and the GitHub Pages site is live.

A lovely education app that makes biodiversity data playable — built with zero stars but very much alive.
