We summarize bird species records submitted to the Committee for Ecuadorian Records in Ornithology (CERO) from July 2013 to March 2014. CERO compiles Ecuador’s official country checklist and updates it annually. We present four new country records (Amazonetta brasiliensis, Porzana albicollis, Haematopus ater, Chroicocephalus Philadelphia), one new country record that antedates earlier records (Vireo flavifrons), first voucher documentation for four species (Larus californicus, Pangara guttata, Conirostrum bicolor, Cardellina pusilla), and 26 significant range extensions or records of rare and poorly known species (Oceanodroma leucorhoa, Oceanodroma hornbyi, Sula leucogaster, Phalacrocorax bougainvillii, Butorides virescens, Ardea herodias, Egretta rufescens, Egretta caerulea, Eudocimus albus, Eudocimus ruber, Anas clypeata, Anas cyanoptera, Aythya afflnis, Gallinago delicata, Limosa fedoa, Larus delawarensis, Hydroprogne caspia, Glaucidium griseiceps, Chloroceryle aenea, Platyrinchus saturatus, Myiarchus crinitus, Tyrannus niveigularis, Knipolegus poecilurus, Doliomis remseni, Setophaga castanea, Lonchura malacca). Three records are from the Galapagos Islands (Oceanodroma leucorhoa, Butorides virescens, Egretta caerulea), while all others were obtained in mainland Ecuador. Six species are eliminated from the Ecuadorian list (Geotrygon violácea, Topaza pella, Attila bolivianos, Pachyramphus rufus, Pachyramphus validus, Lonchura atricapilla). Two additional records were postponed for further expert revision (Thalassarche cauta) or for additional evidence (Neomorphus pucheranit) and three submitted records were rejected (Patagioenas oenops, Hydropsalis maculicaudus, Colaptes rupicola). This information updates our knowledge of the distribution and status of poorly known species in Ecuador, as well as the national bird checklist that currently reaches 1673 species (1608 confirmed with voucher documentation, 65 hypothetical).

Presentamos registros de especies de aves reportados por la comunidad ornitológica internacional y del Ecuador al Comité Ecuatoriano de Registros Ornitológicos (CERO). CERO compila la lista oficial del país y la actualiza anualmente. Presentamos nueve registros nuevos para el país (Anas acuta, Aythya collaris, Egretta rufescens, Coccycua pumila, Sublegatus modestus, Myiarchus panamensis, Vireo philadelphicus, Atlapetes albinucha, Icterus chrysater), cuatro registros presentados en otras publicaciones y validados aquí (Galbula cyanescens, Myiornis albiventris, Tumbezia salvini, Anthus cervinus), la primera documentación de evidencia para 10 especies (Anas clypeata, Podiceps major, Sula leucogaster, Eudocimus ruber, Phimosus infuscatus, Gallinago delicata, Fluvicola pica, Machetornis rixosa, Progne subis, Progne elegans), registros adicionales de dos especies sin documentación de registro en el país (Calidris alpina, Leucippus taczanowskii), 34 extensiones significativas de distribución o registros de especies raras y poco conocidas (Sarkidiornis melanotos, Anas bahamensis, A. cyanoptera, Netta erythrophthalma, Aythya affinis, Oceanites oceanicus, Oceanodroma hornbyi, Sula leucogaster, Tigrisoma lineatum, Ardea herodias, Plegadis falcinellus, Pluvialis fulva, Limnodromus scolopaceus, Limosa fedoa, Chroicocephalus cirrocephalus, Phaetusa simplex, Hydroprogne caspia, Chlidonias niger, Coccyzus euleri, Heliodoxa gularis, Hylocharis humboldtii, Terenura spodioptila, Syndactyla rufosupercilliata, Contopus cooperi, Conopias trivirgatus, Myiarchus swainsoni cf. swainsoni, Myiarchus crinitus, Pyroderus scutatus, Vireo flavifrons, Catharus minimus, Sporophila lineola, Coryphospingus cucullatus, Chlorothraupis frenata, Passerina caerulea, Vermivora chrysoptera, Protonotaria citrea), y dos nuevas subespecies para el país (Eurypyga helias meridionalis y Petrochelidonpyrrhonota melanogaster). Tres registros son de las islas Galápagos, mientras todos los otros reportes fueron obtenidos en el área continental del Ecuador. Esta información actualiza el conocimiento sobre la distribución y estado de las especies poco conocidas de aves en Ecuador, así como el listado nacional de aves que en la actualidad alcanza las 1657 especies (1587 confirmadas y documentadas, y 70 hipotéticas).
