First documented record of Cerulean Warbler Setophaga cerulea (Parulidae) in Brazil

Cerulean Warbler (Setophaga cerulea; Parulidae) is a “Vulnerable” species which breeds in North America and migrates to winter in South America. Here we present the first documented record of the species in Brazil. One male was photographed foraging in the canopy of secondary forest on Santa Catarina island, south Brazil, on 07 April 2018. At the time of the record the species was expected to be on migration north to North America. Since the individual was heading south it is assumed that it was lost. This record can then be potentially explained by the vagrancy theory of reverse migrants.
