Once breeding season is over and the birds have successfully mated and have raised their chicks the birds need to sing or chirp and attract a mate diminishes.
When birds go silent it means that the birds have detected that a predator is close by and they are trying to avoid attention.
By freezing in place and staying hidden and quiet the bird is less likely to be found by other birds that may be preying on them and it's a natural instinct for survival to protect the birds from danger.
Birds will also go silent when breeding season is ending because they no longer need to attract any mates or defend themselves.
During molting season when birds are growing their new features the birds sometimes go quieter to avoid drawing any attention to themselves when they are more vulnerable and when birds prepare for their migration they may also reduce their sounds as they focus on finding food and preparing for their journey.
