How do I make a cladogram? I have five species: finch, cardinal, robin, blue jay, and pelican.

First figure out what ALL of these have in common.

It would probably be the ability to fly since they can all fly.

Then you would pick something that only 4 out of the 5 share.

For that, you can separate the pelican because it's big, unlike the rest.

It starts at the bottom, so the pelican would be all the way at the bottom

Add that characteristic before the name of the animal and keep on making your way up until only 1 of the birds has a characteristic that the other ones don't have
