There are six pelican species worldwide – four occur naturally in Africa, while two exist further afield (Californian Brown Pelican & Peruvian Pelican). Sadly three out of these six species have been classified as being vulnerable to extinction due to habitat loss or human activities such as overfishing or hunting - the Dalmatian Pelican, the White Pelican, and the Peruvian Pelican all fall into this category, according to BirdLife International's latest assessment published in 2015.
