The Azores are internationally recognized as a birding destination for the observing of certain groups of bird species. Due to its central position in the North Atlantic Ocean, it is possible to observe several migratory species which are occasionally seen in the Azores, as the weather throws some of these species off course on their migration route. It is also possible to observe seabirds that nest in the Azores and endemic species and subspecies. The archipelago has approximately 30 breeding species.
