[4], Great white pelicans range over a large area of Africa and southern Asia. [4] Even in the 21st century, an increase in the population of American white pelicans in southeastern Idaho in the US was seen to threaten the recreational cutthroat trout fishery there, leading to official attempts to reduce pelican numbers through systematic harassment and culling. [74] More recently, such predation at South African seabird colonies has impacted on the conservation of threatened seabird populations, especially crowned cormorants, Cape cormorants, and bank cormorants. The pelican consequently prepared to go to war against them by daubing himself with white clay as war paint.

Its metabolite DDE is a reproductive toxicant in pelicans and many other birds, causing eggshell thinning and weakening, and consequent breeding failure through the eggs being accidentally crushed by brooding birds.

The US government has not accepted the elevation of the two taxa into separate species. Many of these do little harm, but flies may be implicated in the death of nestlings, particularly if they are weak or unwell, and the soft tick Ornithodoros capensis sometimes causes adults to desert the nest.
