They are less likely to attract mates and pass on their genes.

Explanation:

The singing of birds uses a lot of energy from their bodies, for this reason, birds that do not eat properly tend to sing less often to save the little energy they have. However, birds only sing when they have motives and the main reason for this song is to attract reproductive partners for mating. With this, we can conclude that if the bird does not eat well, it will have little energy and will not have frequent frequency, so it will be less likely to attract partners and transmit its genes.

Throughout the year, these animals sing more in the spring. This period is the breeding season for birds, who wish to demarcate territory and attract females. In the following season, the summer, the chicks are born, and the singing decreases. In addition to not wanting to attract unwanted visitors to the nest, both the male and the female are totally focused on raising the young.
