Specializing method arguments in subclasses in Java

Consider the following situation:

public abstract class AnimalFeed{
}
public class FishFeed extends AnimalFeed{
}
public class BirdFeed extends AnimalFeed{
}

public abstract class Animal{

public void eat(AnimalFeed somethingToEat)

}

Now I would like to define a class "Bird" extending "Animal" being sure that when the bird eats, it eats only BirdFeed.

One solution would be to specify a sort of contract, in which the caller of "eat" must pass an instance of the appropriate feed

public class Bird extends Animal{

@Override 
public void eat(AnimalFeed somethingToEat){

    BirdFeed somethingGoodForABird

    if(somethingToEat.instanceOf(BirdFeed)){
    somethingGoodForABird = (BirdFeed) somethingGoodForABird
    }else{
    //throws error, complaining the caller didn't feed the bird properly
    }
}
}

Is it acceptable to delegate the responsibility of the parameter to the caller? How to force the caller to pass a specialization of the parameter? Are there alternative design solutions?
