A dead sparrow was found in the new house that was about to move. Are there any signs? Good or bad?

Naturally, it should go in through the air conditioning hole, so there is nothing to pay attention to. If the air conditioning hole is blocked, it will make a nest outside. Unlike people who can find all kinds of exits, sparrows only go in and out in bright places. When the window is brightest, it ignores the hole that comes in, and it will starve to death. It doesn't matter.
