The crow is nesting on the street tree, so please remove it.

Crows are wild animals subject to the Wildlife Protection Act, so they will not be removed just by having a nest.
During the breeding season from early spring to early summer, crows often threaten or attack by treating approaching people as enemies in order to protect their nests and chicks. If a parent bird is attacking, remove the nest after taking procedures such as applying for removal of the Wildlife Protection Law as a damage control.
