Composition of bird communitty in Portachuelo Pass (Henri Pittier National Park, Venezuela)2020 •
The purpose of this study was to describe the composition of the bird community in Portachuelo Pass, located in Henri Pittier National Park, Venezuela. Portachuelo Pass is an important route for migratory birds between northern South America and the Southern Cone. During 11 months of sampling between 2010 and 2012, we captured 1,460 birds belonging to 125 identified species, 29 families, and 9 orders. The families with the highest relative abundance and species richness were Trochilidae and Thraupidae and the most common species were the Violet-chested Hummingbird (Sternoclyta cyanopectus), Olive-striped Flycatcher (Mionectes olivaceus), Plain-brown Woodcreeper (Dendrocincla fuliginosa), Orange-bellied Euphonia (Euphonia xanthogaster), Violet-fronted Brilliant (Heliodoxa leadbeateri), Vaux's Swift (Chaetura vauxi), Red-eared Parakeet (Pyrrhura hoematotis), Golden-tailed Sapphire (Chrysuronia oenone), Black-hooded Thrush (Turdus olivater), and Gray-rumped Swift (Chaetura cinereiventris). These species represented 52.4% of total captures and 8.0% of identified species. We captured 5 endemic species and 8 migratory species. The months of greatest relative abundance and species richness were June and July 2010 and January 2011. Birds captured belonged to the following feeding guilds: insectivorous, nectarivorous-insectivorous, frugivorous, frugivorous-insectivorous, granivorous, frugivorous-folivorous, omnivorous, carnivorous, and frugivorous-graniv-orous. We recaptured 226 individuals, with the highest percentage of recaptures occurring between January and May 2011. Additionally, we report altitudinal range extensions for the Streaked Tuftedcheek (Pseudocolaptes boissonneautii) and the Oleaginous Hemispingus (Sphenopsis frontalis).

• The House Sparrow (Passer domesticus, Passeridae), native to Eurasia and northern Africa, was intro‐ duced to the Americas and Australia where it inhabits mainly urban environments. The objective of this study was to determine the distribution of the House Sparrow in Venezuela from our own observations and data reported in per‐ sonal communications, published material, and eBird records. House Sparrows were recorded for first time in Vene‐ zuela in 1996 at the port of La Guaira. Since then, records have increased, and we found 133 records of the House Sparrow until July 2015, in the states of Falcón, Zulia, Vargas, Miranda, Carabobo, Anzoátegui, and Los Roques Archi‐ pelago. The states of Falcón and Vargas included the greatest number of records, and 2015 was the year with the most records. Most sightings occurred in urban areas of coastal Venezuela. House Sparrows were recorded within three protected areas: Refugio de Fauna Silvestre de Cuare (Falcón), Refugio de Fauna Silvestre y Reserva de Pesca Ciénaga de los Olivitos (Zulia), and Parque Nacional Archipiélago Los Roques. Two records for Caracas, one for Barquisimeto and another for Margarita Island, need confirmation. Breeding was confirmed in five states where the House Sparrow is currently present, and records indicated that the nesting season extends from February to November. Most nests (84%) were located in man‐made structures, but two breeding records included a nesting colony in cavities of an exotic palm (Phoenix sp.) in Falcón and a nest under a pile of dead coral fragments in Los Roques Archipelago. We found evidence of foraging on new food items from two coastal trees (Conocarpus erectus and Coccoloba uvifera). Formal research and long‐term surveys are required to assess the functional ecological role of this exotic species in the avian communities of Venezuela.
