How to Same methods implements (interfaces) in java

/* Class name : Animal.java */
interface Animal {
public void eat();
public void travel();
}
/* Class name : Birds.java */
interface Birds {
public void eat();
public void travel();
}
public class MammalAni implements Animal{
public void eat(){
System.out.println("Mammal eats");
}
public void travel(){
System.out.println("Mammal travels");
}
public static void main(String args[]){
MammalAni m = new MammalAni();
m.eat();
m.travel();
}
}
Here two methods same name but not implements then how to interface
implements in this class.Basically interface inheritances two or more
class but here both different class in same method use then both method
which way implement in one class.
