Abstract

We present new distribution records of birds from Ecuador that have been evaluated by the Committee for Ecuadorian Records in Ornithology (CERO) between October 2019 and November 2021. We incorporate records of three new species in the national list: Hydrocoloeus minutus and Pterodroma externa from Galapagos, and Tachycineta leucorrhoa from mainland Ecuador. In addition, we include documented records of rare or infrequent species in mainland Ecuador, the Galapagos archipelago and the country’s territorial sea, which include seven species considered hypothetical, rare, and erratic throughout Ecuador: Netta erythrophthalma, Limnodromus scolopaceus, Pluvialis fulva, Chroicocephalus philadelphia, Spheniscus humboldti, Egretta rufescens, and Tyrannus dominicensis. We present the first documentation of two species in Ecuadorian territory, Numenius americanus and Macronectes halli from the mainland and territorial sea, respectively. In addition, we include 16 species considered hypothetical or accidental in Galapagos: Sarkidiornis sylvicolaSpatula clypeataPhoenicopterus chilensisFulica americanaLimosa fedoaCalidris canutusCalidris subruficollisStercorarius parasiticusLarus belcheriPelagodroma marinaArdenna creatopusButorides virescensPetrochelidon pyrrhonotaCatharus ustulatusQuiscalus mexicanus, and Parkesia noveboracensis. We also include notable records for both the mainland and Galapagos of Spatula cyanopteraThalasseus sandvicensisNeocrex erythropsSula leucogasterArdea herodiasButorides virescensButeo swainsoniPipreola jucundaProtonotaria citreaGeothlypis philadelphia, and Cacicus latirostris. Finally, we validated distributional expansions of nine species: Dendrocygna autumnalisCairina moschataSarkidiornis sylvicolaAnas georgicaAramus guaraunaAttagis gayiNycticorax nycticoraxEudocimus ruber, and Paroaria gularis. Likewise, we evaluated 12 records that were not accepted based on erroneous identifications and 5 records whose acceptance was postponed because of insufficient descriptive support. Lastly, we discuss records of Aix galericulata and Spheniscus magellanicus, both correctly identified and well documented, but possibly originated by human intervention. After this review and update by CERO, the national list of birds of Ecuador totals 1722 species: 1673 confirmed documented with evidence and 49 species that still require solid voucher evidence.
