I’m not sure, but I guess the bird we saw in the park                 [might have been, can't have been, must have been] a blackbird. They’re quite common here.

Jane                 [might have been, must have been, can't have been] to at least 50 different countries by now – every year she travels for three or four months.

Andrew's plane landed in Malaga three hours ago. I’m sure he          [can't be, must be, might be] at the beach by now.

It's a public holiday tomorrow.There          [must be, may be, can't be] a lot of people at the airport.

This          [can't be, must be, might be] the only direct train to London. I'm sure there are more.

Tom got the train three hours ago, and it only takes one hour to get to London. He          [might be, can't be, must be] there by now

Margaret                 [can't have been, might have been, must have been]in the town centre when she phoned me. I could hear the noise of a busy street.

Wendy                 [must have been, might have been, can't have been] on a safari in Africa last summer. She doesn't have a passport and has never been abroad!

I’m not sure, but the animal we saw                 [must have been, might have been, can't have been] a wild cat. They're common here.
