Tables 1 , 2 . IDentificAtion. In April 2018 , we saw two non-breeding individuals of C. niger flying on the river ( 16°52 ʹ S , 057°24 ʹ W ) together with Phaetusa simplex (Gmelin, 1789) and Sternula superciliaris (Vieillot, 1819) . The individuals of C. niger were identified by their grey wings and back and white head and belly. The birds present with a dark crown and nape, with a black patch behind the eye and an extensive dark patch on the side of the breast ( Gochfeld et al. 2019 ). Figure 3.

Map of known wintering distribution of Chlidonias niger (Linnaeus, 1758) in South America (BirdLife International, Handbook of the Birds of the World 2018). Red circle is the first documented record for the Pantanal wetland and also for the Central region of Brazil. Black circles are secondary records of this species on the coast of Brazil and other places of South America ( Dias et al. 2010 ; Quiroga et al. 2015 ; Gonsioroski; 2018; Franz et al. 2018 ; Wikiaves 2019).

This is the first record of C. niger for the Pantanal wetland and the Central Region of Brazil ( Fig. 4 ) The closest South American localities to our new record is Tres Pozos, Argentina ( 980 km ) and Lagoa de Maricá, Rio de Janeiro , Brazil ( 1,675 km ).
