1 Hour FOREST BIRDSONG Black Screen Audio Only HD

1 Hour forest birdsong sound effect on loop — 1 hour black screen — morning nature.

THIS VIDEO IS A STILL IMAGE — black screen with a small line-art icon in the middle. There is NO ANIMATED VIDEO. Pure audio for hearing-test checks, alarm-replacement loops, study background, sleep timers, or just letting the sound run while you do something else.
