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.
