Nests are build by birds.

Answer 2

Answer:

Nests are built by birds.

Explanation:

We use the auxiliary verbs in the same tenses as that of the main verb of the active sentence for the conversion from active to passive voice. However, the meaning of the sentence remains the same.  

Active Voice uses the ‘Subject + Verb + Object’ format.

E.g. Birds build nests.

Passive Voice uses the ‘Object + Verb + Subject’ format.

E.g. Nests are built by birds.
