Peruvian and Bolivian Birds Timetable May 6, 1991 A petition was filed by the International Council for Bird Preservation (ICBP) to add 53 foreign bird species to the Federal List of Endangered and Threatened Wildlife, including the six Peruvian bird species. December 16, 1991 The Service published a 90-day finding (56 FR 65207), in which the agency determined that the petition presented substantial scientific and commercial information to indicate that listing may be warranted for six of the Peruvian bird species. In the Service’s 90-day finding on this petition, the agency announced the initiation of a status review to list as endangered or threatened under the ESA the following 6 Peruvian bird species: 1. Ash-breasted tit-tyrant (Anairetes alpinus) 2. Junín grebe (Podiceps taczanowskii) 3. Junín rail (Laterallus tuerosi) 4. Peruvian plantcutter (Phytotoma raimondii) 5. Royal cinclodes (Cinclodes aricomae) 6. white-browed tit-spinetail (Leptasthenura xenothorax) The Service initiated a status review to determine if listing each of the 6 species is warranted, and initiated a 60-day public comment period to allow all interested parties an opportunity to provide information on the status of these 12 species of parrots. The public comment period closed on March 8, 2010. July 29, 2008 The Service published in the Federal Register a notice (73 FR 44062) announcing the annual petition findings for foreign species. In that notice, the Service announced listing to be warranted for 30 foreign bird species, including the six Peruvian bird species. September 8, 2008 The Service received a 60-day notice of intent to sue from the Center for Biological Diversity and Peter Galvin over violations of section 4 of the Endangered Species Act for the Service’s failure to promptly publish listing proposals for the 30 warranted species identified in the 2008 ANOR, including the six Peruvian bird species. January 5, 2010 The Service published a proposed rule (75 FR 606) to list these six foreign species as endangered: ash-breasted tit-tyrant, Junín grebe, Junín rail, Peruvian plantcutter, royal cinclodes, and white-browed tit-spinetail. July 24, 2012 The Service published a final rule (77 FR 43433) adding the ash-breasted tit-tyrant, Junín grebe, Junín rail, Peruvian plantcutter, royal cinclodes and white-browed tit- spinetail to the Federal List of Endangered and Threatened Wildlife. .

House Sparrow Eradication Attempt on Robinson Crusoe Island, Juan Fernández Archipelago, Chile
E. Hagen, J. Bonham and K. Campbell Hagen, E.; J. Bonham and K. Campbell. House sparrow eradication attempt on Robinson Crusoe Island, Juan Fernández Archipelago, Chile House sparrow eradication attempt on Robinson Crusoe Island, Juan Fernández Archipelago, Chile E. Hagen1, J. Bonham1 and K. Campbell1,2 1Island Conservation, Las Urbinas 53 Santiago, Chile. <[email protected]>.2School of Geography, Planning & Environmental Management, The University of Queensland, St Lucia 4072, Australia. Abstract House sparrows (Passer domesticus) compete with native bird species, consume crops, and are vectors for diseases in areas where they have been introduced. Sparrow eradication attempts aimed at eliminating these negative eff ects highlight the importance of deploying multiple alternative methods to remove individuals while maintaining the remaining population naïve to techniques. House sparrow eradication was attempted from Robinson Crusoe Island, Chile, in the austral winter of 2012 using an experimental approach sequencing passive multi-catch traps, passive single- catch traps, and then active multi-catch methods, and fi nally active single-catch methods. In parallel, multiple detection methods were employed and local stakeholders were engaged. The majority of removals were via passive trapping, and individuals were successfully targeted with active methods (mist nets and shooting). Automated acoustic recording, point counts and camera traps declined in power to detect individual sparrows as the population size decreased; however, we continued to detect sparrows at all population densities using visual observations, underscoring the importance of local residents’ participation in monitoring. Four surviving sparrows were known to persist at the conclusion of eff orts in 2012. Given the lack of formal biosecurity measures within the Juan Fernández archipelago, reinvasion is possible.

Pese a que en bosques tropicales existen numerosos estudios sobre la formación de bandadas, en bosques templados de Sudamérica esta conducta ha sido escasamente documentada. En este estudio describi- mos la composición de 77 bandadas encontradas en un paisaje forestal de la región del Maule entre 1999-2002, y analizamos si existen relaciones entre las abundancias dentro de las bandadas entre especies. Usando simu- laciones de Monte Carlo analizamos la prevalencia de diferentes especies a formar bandadas y relacionamos la abundancia de las especies entre sí dentro de las bandadas. Cada bandada tuvo en promedio 10,5 individuos y la especie más frecuente fue Aphrastura spinicauda. Pese a que se ha señalado a A.

Morphological and Ecological Evolution in Old and New World Flycatchers (215pp.) Director of Dissertation: Donald B. Miles In both the Old and New Worlds, independent clades of sit-and-wait insectivorous birds have evolved. These independent radiations provide an excellent opportunity to test for convergent relationships between morphology and ecology at different ecological and phylogenetic levels. First, I test whether there is a significant adaptive relationship between ecology and morphology in North American and Southern African flycatcher communities. Second, using morphological traits and observations on foraging behavior, I test whether ecomorphological relationships are dependent upon locality. Third, using multivariate discrimination and cluster analysis on a morphological data set of five flycatcher clades, I address whether there is broad scale ecomorphological convergence among flycatcher clades and if morphology predicts a course measure of habitat preference. Finally, I test whether there is a common morphological axis of diversification and whether relative age of origin corresponds to the morphological variation exhibited by elaenia and tody-tyrant lineages.

En este estudio, usamos datos de redes de niebla y radiotelemetría para determinar el patrón de uso de micro-hábitat por el Cachudito de Juan Fernández (Anairetes fernandezianus), una especie de ave endémica del archipiélago de Juan Fernández (Chile). El individuo seguido por radiotelemetría estableció su ámbito de hogar exclusivamente en áreas centrales del bosque nativo residual. Los modelos regresivos de abundancia y las Funciones de Utilización de Recursos mostraron fuertes preferencias de micro-hábitat por los cachuditos. Los valores de abundancia y utilización de recurso por los cachuditos decrecieron con la distancia al matorral exótico y aumentaron con la distancia a los claros hechos por humanos dentro bosque.

Late evening departure. August 14 Lima to Cusco to Huacarpay Lake After an early breakfast in Peru’s capital Lima, we took a flight to the Andean city of Cusco. Soon after arriving in Cusco and meeting with our driver we headed out to Huacarpay Lake . Unfortunately our arrival time meant we got there when it was really hot, and activity subsequently low. Although we stuck to it, and slowly but surely, we managed to pick up some good birds. On the lake itself we picked out Puna Teal, Speckled and Cinnamon Teals, Andean (Slate-colored) Coot, White-tufted Grebe, Andean Gull, Yellow-billed Pintail, and even Plumbeous Rails, some of which were seen bizarrely swimming on the lake itself, something I had never seen before.

Behavioral Characteristics Serpophaginine Tyrannids
BEHAVIORAL CHARACTERISTICS OF SERPOPHAGININE TYRANNIDS W. JOHN SMITH Department of Biology University of Pennsylvania Philadelphia, Pennsylvania 19104 and Smithsonian Tropical Research Institute Box 2072 Balboa, Canal Zone The tyrant flycatchers comprise a family with the plumages and ranges of its species, seeking unusually broad ecological radiation, but most similarities and differences in general habitat are birds for which we have as yet very little preferences and foraging methods, then con- information about even gross behavior pat- sidering the vocal and visible displays.

Birds can maximize their reproductive success through careful selection of nest-sites. The `total-foliage' hypothesis predicts that nests concealed in vegetation should have higher survival. We propose an additional hypothesis, the `predator proximity' hypothesis, which states that nests placed farther from predators would have higher survival. We examined these hypotheses in the world's southernmost forests of Navarino Island, in the Cape Horn Biosphere reserve, Chile (55◦S). This island has been free of mammalian ground predators until recently, and forest passerines have been subject to depredation only by diurnal and nocturnal raptors. Methods. During three breeding seasons (2014–2017), we monitored 104 nests for the five most abundant open-cup forest-dwelling passerines (Elaenia albiceps, Zonotrichia Submitted 5 February 2020 Accepted 17 August 2020 capensis, Phrygilus patagonicus, Turdus falcklandii, and Anairetes parulus).

This is particularly true for open-cup forest passerines breeding at high latitudes (> 42°). To better understand the ecology of these species, in this study we described and compared the breeding strategies (i.e., nest dimensions, nest height from the ground, egg laying rhythm, clutch size, length of the developmental periods, breeding phenology, and diversity of nesting substrate) of five passerine birds that inhabit sub-Antarctic ecosystems. Methods: During three breeding seasons (2014–2017), we monitored 103 nests of the five most abundant open-cup forest-dwelling passerines (Phrygilus patagonicus, Anairetes parulus, Turdus falcklandii, Elaenia albiceps, and Zonotrichia capensis) on Navarino Island (55°S), Cape Horn Biosphere Reserve, southern Chile. Additionally, we compared the breeding strategies of T. falcklandii to another population breeding at lower latitude (39°S). Results: Most of the species started laying eggs the last week of September; only E. albiceps started 2 months later. During the breeding season of 2016–2017 both E. albiceps and Z. capensis started laying eggs earlier than the previous year.

Molecular Characterisation of Haemoparasites in Forest Birds from Robinson Crusoe Island: Is the Austral Thrush a Potential Threat to Endemic Birds?

JAVIER MARTÍNEZ , RODRIGO A. VÁSQUEZ , CRISTOBAL VENEGAS and SANTIAGO MERINO Summary The Juan Fernández Firecrown Sephanoides fernandensis and Juan Fernández Tit-Tyrant Anairetes fernandezianus are two endemic forest birds inhabiting Robinson Crusoe Island and are classified as ‘Critically Endangered’ and ‘Near Threatened’ respectively by IUCN. Previous research concluded that the two main factors involved in the decline of these birds were habitat degradation and the introduction of predator / competitor species. However, the potential role of parasitic diseases has not yet been explored. In order to explore hypothetical host-switching phenomena, we genetically identified the haemoparasites present in four bird species, the two endemic species mentioned above and two recent colonisers, Green-Backed Firecrown Sephanoides sephaniodes and Austral Thrush Turdus falcklandii . We failed to find infections by different blood parasites ( Plasmodium , Haemoproteus , Leucocytozoon , Trypanosoma , Babesia and Isospora ) in the endangered Juan Fernández Firecrown. However, the Juan Fernández Tit-Tyrant was infected with some parasites shared with the Austral Thrush. The latter species may function as a key-host species on the island as it showed both the higher hemoparaasitic diversity and prevalence. The role of Green-Backed Firecrowns is apparently of lower importance because only one individual was found parasitized. The Austral Thrush could be responsible of the introduction of some parasites also isolated from the Juan Fernández Tit-Tyrant and represent a potential threat to the endemic firecrown due to its role as a reservoir.
