Abstract

Scarce information is available on the trophic ecology and feeding habitats of the Peruvian Tern Sternula lorata. We searched 15 Peruvian Tern colonies along the coast of northern Chile during the breeding seasons of 2008 to 2018 to evaluate the tern's main food source. We collected samples of prey remains found near nests as well as prey items regurgitated by chicks and adults during our visits. We found that the Peruvian Tern is mainly piscivorous, secondarily feeding on some cephalopods and euphausiids. Pacific Saury Scomberesox saurus and Paloma Pompano Trachinotus paitensis were the main prey found near nests, but regurgitated prey was dominated by the Peruvian Anchoveta Engraulis ringens. Fish prey sizes ranged from 36 to 192 mm. These findings expand existing knowledge of the feeding ecology of this endangered seabird during its breeding season. [ABSTRACT FROM AUTHOR]

6. Southernmost limit of the Vicugna vicugna Molina (Mammalia: Camelidae) in Chile: a review of old records and new field data

Author

VILINA, YERKO A, CRUZ-JOFRÉ, FRANCO, and SABAJ, VALERIA

Abstract

Vicugna vicugna Molina is a mammal of relatively large size and conspicuous habits; nevertheless, its southernmost distribution limit in Chile is not well established. Many authors were fixed this limit at 27º30´S, we deliver field information of a distribution limit 140 km further south to the recently proposed. Vicugna vicugna Molina es un mamífero de tamaño relativamente grande y de hábitos conspicuos; sin embargo, su límite de distribución Sur en Chile no está bien establecido. Muchos autores han fijado este límite a los 27º 30’S, nosotros entregamos información de campo de un límite de distribución 140 km más al sur al propuesto recientemente.
