Tersina viridis

A few hundred photographic records on WikiAves from the Brazilian states of Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe and Bahia fall between March and August (WikiAves, 2021), suggesting that the species is a seasonal visitor in northeastern Brazil. Literature records from this region are scarce, but generally corroborate this pattern (e.g., Dantas et al., 2007; Pereira et al., 2012; Silva et al., 2012; Somenzari et al., 2018). The seemingly complex migratory movements of the Swallow Tanager are little known ( Somenzari et al., 2018) and thus further study, especially with tracking technologies such as geolocators, is warranted.
