This is a @creational design pattern and similar to @factory pattern .

Here, we create an AbstractFactory class that return the required type and it acts as a super factory that the concrete factory classes can extend and implement.

abstract AbstractFactory {
 abstract Bird getBird(type);
}

class BirdFactory extends AbstractFactory {
 Bird getBird(type) {
  // Check type and return matched.  
 }
}

The abstract factory is an object and can contain multiple factory methods in it.
