Proposal (760) to South American Classification Committee

Add Chlidonias hybrida (Whiskered Tern) to the Main List

Effect on South American CL: This would add a species to the Main List.

Background: The species has been recently recorded for the first time in Paraguay which also represents the first record for South America:

An adult Whiskered Tern was photographed and observed on 14 January 2016 by R.P.C., Holly Faithfull and Lloyd Stetson (Fig. 1G) at Estancia La Graciela, Misiones dept. Paraguay. The picture and notes clearly match Chlidonias hybrida.

Recommendation: I would recommend a yes vote to add this species to the South American checklist.
