Chromosomal similarity between the Scaly-headed parrot (Pionus maximiliani), the Short-tailed parrot (Graydidascalus brachyurus) and the Yellow-faced parrot (Salvatoria xanthops) (Psittaciformes: Aves): a cytotaxonomic analysis Genet. Mol. Biol.
Caparroz,Renato; Duarte,José Maurício Barbanti.
Behavior, morphology, allozyme studies and DNA hybridization and sequencing data all suggest the independent evolution of the Old and New World parrots and support tribe status for the American species, although the phylogenetic relationships within this tribe are still poorly understood. A previous study has shown that the Yellow-faced parrot (Amazona xanthops Spix 1824) exhibits large karyotypic differences compared to the other Amazona species and suggested that this species should be renamed Salvatoria xanthops, although the relationships between S. xanthops and the other New World parrots remain unclear. In the present work, we describe the karyotype of the Scaly-headed parrot (Pionus maximiliani, Kuhl 1820) and the karyotype and C-banding pattern of...

Communal roosts of the Blue-fronted Amazons (Amazona aestiva) in a large tropical wetland: Are they of different types? Repositório Alice
SEIXAS, G. H. F.; MOURAO, G. de M..
Psittacidae species are among the most threatened birds in the world. Approximately onehalf of the 390 parrot species are experiencing population declines. The Blue-fronted Amazon (Amazona aestiva) is the most traded parrot worldwide and suffers from poaching and habitat loss. Many species of parrots, including the Blue-fronted Amazon, form communal roosts where they spend the night. Under certain circumstances, roost surveys can be a rapid and cost-effective way to obtain information about the demography of parrots or the consequences of threats. We surveyed an area of 2,700 km2 in a large wetland in mid-western of Brazil and located five Blue-fronted Amazon roosts. We conducted monthly counts of the birds arriving at these roosts for 28±61 months and...

Geophagy in two parrot species in southern Pantanal, Brazil Biota Neotropica
Severo-Neto,Francisco.
Geophagy is a habit recorded for parrots, which seek earthy or soil-like substances presumably to help them in digestive functions, whether mechanical or chemical ones. Few studies are devoted to this feeding peculiarity in the Pantanal region. Here are reported two events of geophagy, for the Blue-and-yellow Macaw (Ara ararauna) and the Nanday Parakeet (Aratinga nenday) in the Pantanal subregions of the Miranda-Abobral and Nhecolândia, Mato Grosso do Sul, respectively.

Haematological reference for red-browed parrot ( Amazona rhodocorytha , Salvadori, 1890) captive in the Atlantic Forest in Eastern Brazil Arq. Bras. Med. Vet. Zootec.
Mello,R.H.; Martins,R.F.; Bonissi,D.A.; Júnior,J.L.B.; Melotti,T.; Bianchi,H.; Bianchi,M.A.F..
ABSTRACT To conduct the survey were used 35 (thirty-five) red-browned parrots (A. rhodocorytha), adults, captive, of both genders and clinically healthy, belonging to the live collection of the Museum of Biology Teacher Mello Leitao, located in Santa Teresa, Espírito Santo, Brazil. Harvests were performed in the morning, by puncture of the brachial vein getting 0.5mL of blood stored in EDTA for a period no longer than 6 hours. Blood smears of fresh material were made at collection, stained using the method of May-Grunwald-Giemsa. Analysis of blood elements was done by cell counting in a mirrored Neubauer chamber using Natt and Herrick solution at a ratio of 2:200 as diluent. For the analysis of the methodology, homoglobinometry cyanide hemoglobin using...

Molecular markers for population genetic analyses in the family Psittacidae (Psittaciformes, Aves) Genet. Mol. Biol.
Faria,Patrícia J.; Miyaki,Cristina Y..
The selection of molecular markers for population studies is an important tool for biodiversity conservation. The family Psittacidae contains many endangered and vulnerable species and we tested three kinds of molecular markers for their potential use in population studies of five psitacid species: 43 hyacinth macaws (Anodorhynchus hyacinthinus), 42 blue-and-yellow macaws (Ara ararauna), 23 red-and-green macaws (Ara chloroptera), 19 red-spectacled amazons (Amazona pretrei); and 18 red-tailed amazons (Amazona brasiliensis). We tested 21 clones from a genomic library of golden conure (Guarouba guarouba) minisatellites and 12 pairs of microsatellite primers developed for the domestic chicken (Gallus gallus) and A. hyacinthinus. We also tested seven...

Observations of parrots at a geophagy site in Bolivia Biota Neotropica
Mee,Allan; Denny,Rebecca; Fairclough,Keith; Pullan,Dave M.; Boyd-Wallis,Will.
Geophagy, or soil ingestion, is known from a wide range of animal taxa but is particularly common among macaws and parrots in the family Psittacidae. Current theory suggests that Neotropical parrots ingest soil to neutralize toxins in food such as seeds and unripe fruit and as a mineral supplement. Here, we document the occurrence of geophagy at a site in lowland forest in Bolivia. We recorded six species of parrot with a maximum of 1,044 birds on any one day. Aratinga weddellii, Pionus menstruus and Ara severa (maxima of 654, 337 and 108 birds respectively) were the most numerous species visiting the site. We recommend that the Valle de la Luna be afforded formal protection by incorporating the site into the nearby Parque Nacional Carrasco.

Relationship betwween weight age and hatching success and the concentrtion of heavy metals in nestling blue macaw (Anodorhynchus hyacinthinus Latham, 1790) in he Pantanal, Mato Grosso do Sul. Repositório Alice
MARCHESI, M. D.; ROSSI, J. L.; GUEDES, N. M. R.; CARNEIRO, M. T. W. D.; ENDRINGER, D. C.; CAMARGO FILHO, C. B..
The concentration of heavy metals (Cr, Fe, Al, As, Cd, Cu, Pb, Mo, Ni, Se and Zn) was evaluated in the blood of nestling blue macaws (Anodorhynchus hyacinthinus) captured in the Pantanal, Mato Grosso do Sul (n=26) in 2012; this was based on the ypothesis that these birds exhibit levels of these heavy metals in their organism and that these interfere in hatching success, weight and age of the chicks. Blood samples were digested with nitric acid and hydrochloric acid and the quantification of metals was performed by ICP-OES (Optical Emission Spectroscopy and Inductively Coupled Plasma). Blood samples of nestlings showed concentrations of Cr (0.10μg/g) Fe (3.06μg/g) Al (3.46μg/g), Cd (0.25μg/g) Cu (0.74μg/g), Mo...
