We present new distributional records of birds in Ecuador submitted to the Committee for Ecuadorian Records in Ornithology (CERO) from September 2015 through July 2017. This report includes four species new to Ecuador (Plegadis ridgwayi, Cathartes burrovianus, Malacoptila mystacalis, Vireo gilvus), two species new to Galapagos (Calidris pugnax, Larosterna inca), five species with first documented country records (Fregata minor, Syrigma sibilatrix, Calidris pugnax, Larus belcheri, Sternula antillarum), remarkable range extensions for eight species (Anas bahamensis, Fregata sp., Jabiru mycteria, Phimosus infuscatus, Caracara cheriway, Larus dominicanus, Chloroceryle aenea, Sturnella militaris), new records of eight rare species (Anhima cornuta, Mustelirallus albicollis, Larus argentatus, Larosterna inca, Myrmoborus lugubris, Machetornis rixosa, Progne elegans, Conirostrum bicolor) and new records of Nothoprocta curvirostris and Tyrannus tyrannus. We present the first Ecuadorian records of three subspecies (Tolmomyias sulphurescens insignis, Myiarchus swainsoni phaenotus, Oxyura jamaicensis andina, although the taxonomic validity of the latter is debated). Further we discuss the subspecific identity of Petrochelidon pyrrhonota in Ecuador. Finally, we invalidate previous records of 43 species for mainland Ecuador and 6 species for Galapagos, as published in different sources, and reject a remotesensing record of Cypseloides niger. CERO revises and updates the country bird list, which currently stands at 1690 species (1632 confirmed and documented; 58 undocumented).

Presentamos nuevos registros de distribución de aves del Ecuador que han sido presentados al Comité Ecuatoriano de Registros Ornitológicos (CERO) entre abril 2014 y agosto 2015. Incluimos reportes de seis especies nuevas para Ecuador (Anas crecca, Thalassarche bulleri, Puffinus puffinus, Morus sp., Numenius americanus y Elaenia strepera), una especie nueva para el Ecuador continental (Fregetta grallaria), cuatro especies con primera documentación en Ecuador (Calidris alpina, Larus argentatus, Stercorarius longicaudus, Tyrannus dominicensis), extensiones considerables de distribución de 14 especies (Podilymbus podiceps, Pterodroma phaeopygia, Charadrius semipalmatus, C. collaris, Bartramia longicauda, Calidris alba, Limnodromus scolopaceus, Phalaropus fulicarius, Stercorarius longicaudus, Sternula superciliaris, Chlidonias niger, Galbula dea, Elaenia spectabilis y Geothlypis philadelphia) y nuevos reportes de 12 especies raras (Aythya affinis, Sula leucogaster, Busarellus nigricollis, Stercorarius chilensis, Chordeiles minor, Psittacara wagleri, Philydor fuscipenne, Muscisaxicola fluviatilis, Pyroderus scutatus, Passerina caerulea, Vermivora chrysoptera y Setophaga castanea) y el primer reporte moderno de Oreopholus ruficollis. Además, presentamos el primer registro en Ecuador de Lurocalis semitorquatus semitorquatus y el segundo registro de la subespecie Petrochelidon pyrrhonota melanogaster. Finalmente, invalidamos los registros previos de Picumnus castelnau, especie que no habita en Ecuador. CERO revisa y actualiza el listado nacional de aves, que en la actualidad alcanza las 1678 especies (1626 confirmadas y documentadas, y 52 no documentadas).

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.

We summarise records of bird species submitted to the Committee of Ecuadorian Records in Ornithology (CERO) by the Ecuado-rian and international ornithological community. CERO compiles the official country checklist and updates it annually. We present nine new country records (Anas acuta, Aythya collaris, Egretta rufescens, Coccycua pumila, Sublegatus modestus, Myiarchus panamensis, Vireo philadelphicus, Atlapetes albinucha, Icterus chrysater), four country records presented elsewhere and herein validated (Galbula cyanescens, Myiornis albiventris, Tumbezia salvini, Anthus cervinus), first voucher documentation for eight 10 species (Anas clypeata, Podiceps major, Sula leucogaster, Eudocimus ruber, Phimosus infuscatus, Gallinago delicata, Fluvicola pica, Machetornis rixosa, Progne subis, Progne elegans), additional records of two undocumented species in Ecuador (Calidris alpina, Leucippus taczanowskii), 34 significant range extensions or records of rare and poorly known species (Sarkidiornis melan-otos, Anas bahamensis, A., and two new subspecies for the country (Eurypyga he-lias meridionalis and Petrochelidon pyrrhonota melanogaster). Three records are from the Galapagos Islands of Ecuador, while all others were obtained in the continental area of Ecuador. 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 1657 species (1587 confirmed and documented, 70 hypothetical).

A new subspecies of Amazilia Hummingbird Amazilia amazilia is described from the Ecuadorian Andes. It appears to be closest related to A. a. alticola from southern Loja and adjacent parts of Zamora-Chinchipe provinces in southern Ecuador.

This is a fully revised and expanded edition of the 3 CD publication published in 1999 by Moore et al and contains almost all of the original recordings, about 700 new recordings and 23 additional species. The publication consists of a CD containing all vocalizations in MP3 format and a data DVD with all recordings presented in WAVE format arranged into folders for 7 CDs. Also included is a comprehensive booklet in both digital (PDF and Excel) and hard copy format containing recording information for each cut. We present 1128 separately announced recordings of 213 species and include the sounds of nearly all the birds predominantly inhabiting the humid life zones of the upper foothills and lower subtropics on the northwestern Andean slope of Ecuador. Most of the species which range from the coastal lowlands into the foothills are not included in this publication since many have been previously published in The Birds of Northwest Ecuador, Vol.2: The Lowlands and Lower Foothills (Jahn et al. 2003) and will also be included in our forthcoming comprehensive revised edition of the former publication. The mid-elevation montane and premontane forests of northwest Ecuador support a wealth of birdlife, including a large number of species and subspecies endemic to the exceptionally rich "Chocó Faunal Region." This important biogeographic area extends northward into western Colombia, and this is the first audio publication to feature a large number of these endemics. For some of the wider-ranging species included in this publication, the discerning listener will note certain differences between the vocalizations presented and those of the same species (but usually a different subspecies) found elsewhere.

This 5 CD publication includes the voices of all the birds typical of western and Interandean Ecuador, except for many of those that are also found in the northwest and in the high Andes which were already covered in three previous CD publications by John V. Moore Nature Recordings. However, some of the latter are repeated in the present publication because they also commonly range into the drier zones of the Southwest. The goal of this publication is to achieve a high degree of completeness, including not only songs but also a wide variety of calls. We thus present almost 1000 vocalizations for the 235 species that are included. Whenever we included a species with a range extending beyond the southwest, we predominantly used recordings made in the southwest. We excluded recordings of any subspecies not found in the Southwest. The habitats covered are diverse and range from desert, desert scrub and dry forest to humid forest, and also include lakes, marshes, salt ponds, sandy beaches and mangroves.

Features almost 1000 separate vocalizations from 235 species found in Southwestern Ecuador. The habitats covered are diverse and range from desert, desert scrub and dry forest to humid forest, and also include lakes, marshes, salt ponds, sandy beaches, and mangroves.
