At the top of page 249, in the second paragraph, we can read :

The second method, eat(), is overridden in the subclass Eagle ... the return type of the method in Eagle must be a subclass of the return type of the method in Bird. In this example, the return type void is not a subclass of int ...


But, according to the example of page 248, the explanation should be :

In this example, the return type int is not a subclass of void ...


since the return type of eat() is int in Eagle, and void in Bird.

Is that correct?

Yes! The return types are switched. So you have spotted another minor errata item
