A cozy building and light simulation game where you observe birds, create custom birdhouses, and help a living urban tree grow. Balance sound, diversity, and neighbor reactions as you shape a calm, reactive environment.

The Birdsong Tree is a cozy building and light simulation game set around a single growing tree in the middle of a city. Birds arrive in real time, each with different needs and behaviors. By observing them, building custom birdhouses, and shaping the environment, you influence which species stay, how they sound together, and how the surrounding neighbors react.

As your tree fills with life, it grows vertically, unlocking new branches, modules, and bird species. Balance biodiversity, soundscape, and urban harmony while experimenting with weather, time of day, and placement. There are no fail states — only a living system that responds to your decisions.
