Question

how do birds show parental care?​

Answer 1

Explanation:

Bi-parental care is the most common form in birds, especially in passerines. A mating pair equally contributes to feeding and guarding the offspring. It occurs in approximately 85% of bird species. The hatchling benefits from the mutual care at the cost of the parents' future reproductive success.
