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 - 920. 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).
