Question

How do you rewrite the following sentence in the present tense?
The birds will be returning from their migration soon.

Answer 1

Hint: Present tense is a tense expressing an action that is currently going on or habitually performed, or a state that currently or generally exists. Example: I am a good human.

Complete answer:
Tenses demonstrate the time of an action in a sentence usually performed by or centered around the subject of the sentence. The actions are called verbs. Verbs change according to tenses and other issues. As verbs are the most important elements of English sentences, tenses also carry paramount importance in English grammar.
Present tense: The present tense is a verb tense used to describe a current activity or state of being. However, somewhat unusually, the present tense can also be used to describe past and future activities. For example:
I swim in the sea every Saturday.
(This is a current activity.)

Given question
The birds will be returning from their migration soon.
It can be written in the following ways:

Simple present : The birds return from their migration.
Present Continuous : The birds are returning from their migration.
Present Perfect : The birds have returned from their migration.
Present Perfect Continuous : The birds have been returning from their migration.

Note: The present tense (abbreviated pres or prs) is a grammatical tense whose principal function is to locate a situation or event in the present time. The present tense is used for actions which are happening now.
