Counts during the 2001–02 breeding season showed that the colony extended along 9 km of a sandstone cliff facing the Altantic Ocean, in the province of Río Negro, Patagonia, Argentina, and contained 51412 burrows, an estimated 37527 of which were active. To our knowledge, this is largest known colony of Psittaciformes. Additionally, 6500 Parrots not attending nestlings were found to be associated with the colony during the 2003–04 breeding season. We monitored activities at nests and movements between nesting and feeding areas. Nestlings were fed 3–6 times daily. Adults travelled in flocks of up to 263 Parrots to the feeding grounds in early mornings; later in the day, they flew in smaller flocks, making 1–4 trips to the feeding grounds.

  • Reproduction and Molt in the Burrowing Parrot.-The Burrowing Parrot (Cyunoliseus Patugonus) Has One of the Southernmostranges of Neotropicalparrots
    SHORT COMMUNICATIONS 107 Wilson Bull., 99(l), 1987, pp. 107-109 Reproduction and molt in the Burrowing Parrot.-The Burrowing Parrot (Cyunoliseus patugonus) has one of the southernmostranges of neotropicalparrots. In Argentina, it occurs from the arid Andean slopesin the northwest (24”s) to the Patagonian steppe in the south (46%) (Forshaw 1978). The parrot, which nests colonially in burrows dug into cliff faces,is shot as an agricultural pest and has recently been exported in large numbers for the pet trade, causinglocal declines in its population (Ridgely 1980). Here, we report on the cycle of wild BurrowingParrots in terms of changesin body weight, fat deposits,gonadal condition, and molt. Study area and methods. -The study area was between 33” and 33”3O’Sand 66” and 67”W in the plains near the Sierras de San Luis, San Luis province, central Argentina. The pre- dominant vegetation is an open dry woodland savanna mixed with grasslands.Dominant tree speciesinclude Geofroea decorticans, Prosopis caldenia, P. chilensis, and P. jlexuosa, all of whose fruits are eaten by Burrowing Parrots. Annual rainfall, which is concentratedin the summer (November-April), averages69.5 cm. Mean annual temperatureis 17°C (Instituto National de TecnologiaAgropecuaria, Villa Mercedes Experimental Station, 30 km east of the study area). We obtained parrots from farmers involved in control campaigns,as the Burrowing Parrot is considereda pest by local authorities. We obtained 7-35 parrots monthly from September 1978 to August 1979, with the exception of December 1978, when only two birds were obtained. Birds came from Paso de las Carretas,near Eleodoro Lobos, except in May, June, and July 1979, when all but a few parrots had left the area, and the sample was completed with birds obtained in Alto Pencoso,about 100 km west.

Most of our knowledge of reproduction of wild parrots in the Neotropics comes from studies of tropical lowland species, with few studies addressing species of high-altitude forests. We studied the reproductive biology of Tucuman Parrots (Amazona tucumana) in north-western Argentina between 2004 and 2009. We obtained data on reproductive output for 86 nests and on causes of mortality for 94 nests. Mean clutch-size per nesting attempt was 3.6 eggs Æ 1.0 (s.d.). Hatching success (proportion of eggs laid that hatch) was 0.77 Æ 0.17. Fledging success (proportion of nestlings that fledge) was 0.83 Æ 0.13. The overall breeding success (mean number of fledglings per laying female per year) was 2.3 Æ 0.8. Overall finite nesting success (daily survival rate to the power of the nesting length) was 0.53 Æ 0.27, and chick finite nesting success rate was 0.74 Æ 0.22.

Abstract The Burrowing Parrot, Cyanoliseus patagonus (Vieillot, 1817) [Aves: Psittacidae], is one of the most southern Neotropical parrots. They require sandstone, limestone, or earth cliffs where they excavate their colonial nest-burrows. Adult C. p. patagonus excavate their own nest-burrows, most of them about 1.5 m deep.Each burrow is occupied by a single pair that lay one clutch of two to five eggs per year, directly on the sand of the breeding chamber. The breeding birds abandon the place until the start of the next breeding attempt in the following year. Burrow nests from Río Negro province (Argentina) are inhabited by two ectoparasitic insects, the flea Hectopsylla narium (Siphonaptera: Pulicidae), and Cyanolicimex patagonicus, gen. n., sp.

  • Illegal and Legal Parrot Trade Shows a Long-Term, Cross-Cultural Preference for the Most Attractive Species Increasing Their Risk of Extinction
    Illegal and Legal Parrot Trade Shows a Long-Term, Cross-Cultural Preference for the Most Attractive Species Increasing Their Risk of Extinction Jose´ L. Tella*, Fernando Hiraldo Department of Conservation Biology, Estacio´n Biolo´gica de Don˜ana (CSIC), Sevilla, Spain Abstract Illegal trade constitutes a major threat for a variety of wildlife. A criminology framework has been recently applied to parrot poaching in Mexico, suggesting an opportunistic crime in which the most abundant and accessible species, and not the rare or highly priced species, were poached more often. We analyzed this information, together with additional long-term data (1981–2005) on both the legal and illegal trade of the 22 Mexican parrot species (n = 31,019 individuals), using multivariate statistics and hypothesis-testing approaches. Our results showed a selective capture of parrot species attending to their attractiveness. Parrot species widely differed in attractiveness to people (as reflected by their combined measures of body size, coloration, and ability to imitate human speech), and their attractiveness strongly correlated with their prices both in the Mexican and US markets. The most attractive and valuable species (amazons and macaws) were disproportionally caught attending to the number of years they were legally trapped. Similar patterns were found for parrots poached for the domestic Mexican market, for those smuggled to the USA, and for those legally exported before or after 1992, when the USA ban led parrot exports to be mostly directed to European countries. Finally, the long-term cross-cultural preference for the most attractive species has led them to be among the most threatened species today.

BARQUEZ & MÓNICA DÍAZ e20181136 Abstract: Fleas of Argentina are receiving renewed systematic interest, but the identification of many species associated with small mammals can be problematic. We review the taxonomy of the flea genus Agastopsylla including the re-description of two 92 (1) species and one subspecies, and designate neotype and neallotype for Agastopsylla 92(1) hirsutior, neotype for Agastopsylla nylota nylota from the “Colección Mamíferos Lillo Anexos” (CMLA), Universidad Nacional de Tucumán, Argentina, and neotype and neallotype for Agastopsylla pearsoni from the Natural History Museum (London, U.K.). Additionally, a key to identification of the species of Agastopsylla and a distribution map of the species of the genus are included. Key words: fleas, systematic, type specimens, rodents, key identification. INTRODUCTION Agastopsylla guzmani Beaucournu et al. 2011 (Beaucournu et al. 2014, Lareschi et al. 2016).
