Bird Taxonomy

The classification of Birds is a controversial & debatable topic and thus the same has been undergoing changes from time to time. These changes are continuing still. Owing to the absence of a single authority on bird classification(though the same may be a solution for the sake of it and definitely does not guarantee proper classification) and new findings (based on DNA affiliations, anatomy etc.)from time to time, the problem of classification has not been solved yet.
Given below are the Classification of birds into Orders & Families
