List of Documented Bird Species from the Municipality of Ubatuba, State of São Paulo, Brazil Volume 52(21):233-254, 2012 LIST OF DOCUMENTED BIRD SPECIES FROM THE MUNICIPALITY OF UBATUBA, STATE OF SÃO PAULO, BRAZIL 1,3 RICK SIMPSON 2 VAGNER CAVARZERE 1,4 ELIS SIMPSON ABSTRACT Although preliminary surveys have been conducted at the Atlantic Forest of Ubatuba, there is no list of documented bird records from this coastline municipality. To organize such a compi- lation, we searched the literature and a number of different sources for all documented records of birds from Ubatuba, state of São Paulo. We further carried out a 7-year non-systematic bird inventory in different regions and elevations to document the species within the municipality. The total number of documented bird species is 417, 11% of which are endemic to Brazil. An- other 26% are Atlantic Forest endemics and as many as 60 species are under threat categories, including near-threatened birds, in the state. Some 49 species of 27 families are reported from the municipality but still lack documentation. Considering historical records, no species have extinguished from the municipality. Ubatuba is one of the most studied regions along Serra do Mar in São Paulo regarding its ornithology, but there are still high-elevational gaps that will yield significant additions of species to the area with increasing surveying efforts.

Accepted on 18 November 2014. ABSTRACT: Although the Atlantic forest is the best-studied Brazilian phytogeographic domain, few coastal municipalities of the state of São Paulo can count on published and critically revised bird species list, which are important initial steps to organize conservation inniciatives. Here we present historical records from Bertioga, a northern coastline municipality of the state of São Paulo, as well as recent records obtained in surveys during the past years within the municipality. Surveying methods, carried out between 2008-2011, included point counts, 10-species lists, transect counts and mist nets. This compendium resulted in 330 documented species, 90 of which still await documentation. Of these 420 bird species, 85 (20.4%) are Atlantic forest endemic species and as many as eight, six and 23 are threatened at the global, national and state levels, respectively. Seventeen species are reported from Bertioga for the first time.

    Wilson Bull., 104(l), 1992, pp. 55-64 CYPSELOIDES STORERI, A NEW SPECIES OF SWIFT FROM MEXICO ADOLFO G. NAVARRO S., ’ A. TOWNSEND PETERSON,~ B. PATRICIA ESCALANTEP.,3 AND HESIQUIO BEN~TEZ D. ’ Artsr~~cr.-A new species of swift (Cypseloidesstoreri) is described and given the English name White-fronted Swift. It apparently is most closely related to C. cryptusof Central America and northern South America. It is known from four specimens obtained in Mi- choacln and Guerrero in southwestern Mexico. Received6 June 1991, acceptedI Sept. 1991. RESUMEN.-Se describe una especie nueva de vencejo (Cypseloidesstorer& a la cual se le da el nombre comin de Vencejo de Frente Blanca. Aparentemente, se encuentra muy cercanamente relacionado a C. cryptusde Centro y Sudamerica. Se conoce por cuatro especimenes recolectados en 10s estados de Michoacan y Guerrero en el suroeste de Mexico. Swifts are among the most poorly known families of birds. Several species new to science have been described relatively recently (e.g., Ei- senmann and Lehmann 1962, Collins 1972) and many species are known from relatively few specimens. Here, we describe a new species of swift from the mountains of southwestern Mexico. During the course of seven years of field work in the Sierra Madre de1 Sur of Guerrero by the Museo de Zoologia (MZFC), one specimen of a medium-sized, dark swift was collected at Puerto de1 Gallo, a small ranch on the coastal slope of the Sierra de Atoyac of southern Guerrero. The bird was found clinging to a towel in camp late on a foggy night. Although it was initially identified as a Black Swift (Cypseloidesniger), our exam- ination of the specimen and comparisons with specimens of other swifts led us to conclude that the bird represents a new taxon.

    Cotinga 27 Distribuição e biologia do andorinhão-preto-da-cascata Cypseloides fumigatus e do andorinhão-velho-da-cascata C. senex no Brasil: uma síntese Renata Stopiglia e Marcos A. Raposo Received 26 September 2005; final revision accepted 21 June 2006 Cotinga 27 (2007): 49–57 Two species of the genus Cypseloides occur in Brazil, Great Dusky Swift C. senex and Sooty Swift C. fumigatus. Our lack of basic knowledge of these species is attested by the relative lack of specific publications on these birds. We investigated the biology and distributions of C. senex and C. fumigatus based on an analysis of the principal Brazilian scientific collections of birds. Overall, C. senex occurs from Pará and Maranhão (Brazil) south to Misiones (Argentina), and breeds in both the littoral and interior. C. fumigatus occurs from Espírito Santo (Brazil) to Misiones. Whilst C. senex forms large colonies, which are attended all year, at waterfalls, C. fumigatus almost exclusively occurs within the Atlantic Forest region, departing its breeding sites (humid caves) post- breeding. There is no clear evidence for migratory habits in either species.

La distancia maxima entre localidades de cría fue de 60 km en un pequeño area. Encontramos ocho nidos activos entre Noviembre y Enero. Los nidos estuvieron ubicados a 2.5 (n = 2), 4, 7, 25, 35 (n = 2) y 40 m con respecto al suelo, en comparación a registros pre- vios de alturas de 2.5 m. La mayoría de los nidos estaban expuestos al spray de las cascadas, contrari- amente a registros previos. Estos datos sugieren una mayor plasticidad en la elección de sitios de anidación.
