Notes

  • S5897 - Trolliet., B. In litt. 2012. The species has almost disappeared from the Inner Niger Delta. It is more common in the Lake Chad Basin, but recent counts do not exceed 2,000 birds in Senegal Delta+Inner Niger Delta+Lake Chad Basin. The species occurs outside the areas covered by the waterbirds counts, in more Southern regions of West Africa. But this would add at most a few thousand birds, and even 10,000 would be a too high estimate.
  • S5 - Trolliet, B. in litt 2012. The species almost disappeared from the Inner Niger Delta. It is more common in the Lake Chad Basin, but our recent counts do not exceed 2,000 birds in Senegal Delta+Inner Niger Delta+Lake Chad Basin. The species occur outside the areas covered by the waterbirds counts, in more Southern regions of West Africa. But this would add at most a few thousand birds, and even 10,000 would be a too high estimate.
  • S8691 - 2,000 recorded at Zakouma (Chad) in 2014, indicating possibility of reasonable numbers still in areas not often surveyed.
  • T6754 - The population has gone through significant long-term decline and the continuation of population decline is assumed by several authors (Trolliet in litt. 2011, Dodman 2014, Morrison, in litt. 2014).
