Triggers don't detect collisions :(

Hello all! I am a beginner in unity, so it’s propably a small thing. I have a problem with a collision detection. I am trying to make flappy bird with yt tutorial (clony bird by quill18creates). I added an object(called BGLooper), that is a rigidbody2d collider2d trigger. It is a child of a MainCamera, that moves right with the bird. I’ve added a trigger colliders in background and wrote a script to send log message, when BGLooper hits this background triggers (onTriggerEnter2D). When I hit play button, no log messages happen. Can you help me with this problem?

p.s. This Project is attached in this thread.

It’s OnTriggerEnter2D, not onTriggerEnter2D.
