Ecuadorian Committee Ornithological Records, hypothetical records, new country records, range extensions, birds of Ecuador.Abstract
We present new bird records from Ecuador as evaluated by the Committee for Ecuadorian Records in Ornithology (CERO) between December 2021 and July 2025. We present the first country records of five species: Columbina squammata, Poikilocarbo gaimardi, Nonnula ruficapilla, Myiarchus semirufus and Vireo altiloquus, all from mainland Ecuador, and one species reported for the first time in mainland Ecuador (Pterodroma externa), which was previously reported only from Galápagos. We also showcase the first documentation of three species previously included in the country bird checklist on the basis of undocumented sightings: Chaetura chapmani, Thaumasius taczanowski and Laterallus flaviventer, and present the first documentation of breeding in Ecuador of Paroaria coronata. Further, we present new data on the distribution of 20 rare or poorly known species in Ecuador and its territorial seas, including remarkable range extensions (Nothoprocta curvirostris, Penelope ortoni, Crax rubra, Odontophorus stellatus, Thalassarche bulleri, Pelecanoides sp., Anous minutus, Vanellus resplendens, Haematopus ater, Sternula antillarum, Phaetusa simplex, Steatornis caripensis, Lophornis verreauxi, Crotophaga major, Conopias parvus, Syrtidicola fluviatilis, Tyrannus dominicensis, Tyrannus savana, Oporornis agilis, and Quiscalus mexicanus). We evaluated 12 records that were rejected due to misidentification or that were postponed for insufficient documentation. Last, we discuss four special cases of new information on: Zimmerius chrysops in northwestern Ecuador, Elaenia pelzelni in fluvial islands in extreme eastern Ecuador, a record of Geothlypis sp. (velata or aequinoctialis) in the northeastern Andes and one Xanthocephalus xanthocephalus whose arrival to Ecuador may have been human-assisted; we also accept removing Chloropipo flavicapilla from the country checklist. The most updated version of the official checklist of the birds of Ecuador by CERO has 1735species (1685 documented and confirmed, 50 undocumented).
