Bird Sounds?!?

tonight, I just got back trang chủ from long ngày at work and it is 10pm rn but around the time is truck 10..i heard bird sounds and this is the first time EVER hearing bird sounds around my house but it was weird chirping...then after 2 bird calls...it stopped.

please tell me and I am not crazy if this is normal hoặc it's Peter giving me a sign...with birds.
