The increases are coming from the "kfb". That's a way of increasing in a stitch and looks like this
. I've linked to the english style video but there's also a video for continental on the Glossary tab at the top of the page.
Rows 3, 5, and 7 each have 2 kfb so that'll increase the stitch count by 2 in each of these rows.
Good luck with the owl and let us see a photo when you finish, if you'd like.
