The Southern Lapwing (Vanellus chilensis) was a bird species that only occasionally visited the islands of Aruba, Bonaire and Curacao and was known as an infrequent visitor from South America. Now it is a breeding bird.
There is almost no greater difference between young and adult stages as there is in the taxonomic class of insects. Butterflies are often the most ‘in your face’ example of this fact. Take Monarch butterflies for instance.
