I was reading Lingua Latina Per Se Illustrata to practice my fluency of understanding simple sentences. In the tenth chapter, Bestiae et Homines (page 69), I came across a description of eagles.

Aquila est magna avis fera, quae parvas aves capit et est.

I quickly translated it as that which follows.

An eagle is a large and untame bird, which captures small birds and... is?

I thought that, of course, an eagle might eat smaller birds, but why is est used? Can esse also mean to eat? I checked many online dictionaries, but was unable to find any alternative definitions related to the action of eating.

The words used in this book are very basic, as it's for beginners. I've never discovered a word which I had to look up until now.
