Abstract

In Panama, the White Tern Gygis alba is a vagrant seabird that has been reported very rarely. Its first record was in 1983, during a very strong El Niño Southern Oscillation (ENSO) event that generated a massive invasion of unusual seabirds from South America into the Panama Bay. Unlike other vagrant seabirds, the White Tern remained unrecorded again until 2016. This note reports the second, and first confirmed, occurrence of White Tern to Panama, along with separate confirmed sightings in 2019. We briefly review these records and their potential connections to ENSO events.
