A first evaluation on the use of Ardea albus feathers as bioindicators of mercury burden in Amazonian ecosystems Acta Amazonica
Gomes,Andreza Lourdes; Vieira,José Luiz Fernandes; Pinheiro,Maria da Conceição Nascimento; Marceliano,Maria Luiza Videira.
We evaluated in this study the total mercury concentration in feathers of Ardea albus collected in a colony located in the city of Belem-PA, Brazil in a prospective trial for its use as bioindicators of mercury burden in Amazonia ecosystems. An Atomic absorption spectrophotometry with gold amalgamation was used for the metal determination. The total mercury average concentration in body feathers was 2.2 ± 1.5 µg.g-1 and 1.3 ± 0.9 µg.g-1 in wing feathers. No correlation was observed between total mercury concentration and the length of body or wing feathers. Total mercury concentration was above 5 µg.g-1 dry weight in only one body feather sample.

A gap analysis of ornithological research in the brazilian state of Roraima Biota Neotropica
Santos,Marcos Pérsio Dantas.
This study analyzes the ornithological data available for the Brazilian state of Roraima, focusing on sampling gaps. All ornithological data collected in Roraima up to the present were collated with the aim of answering the following questions: (a) which sites have been well sampled? (b) Are there are any geographic gaps? (c) What is the current extent of the scientific knowledge of avian diversity in Roraima? (d); Which regions and vegetation types have been well-sampled, and which should be prioritized for future surveys? Ornithological data were obtained from a total of 82 localities, including the Maracá Ecological Station (442 species), Viruá National Park (420 species), Colônia do Apiaú (320 species), Mucajaí (267 species), and Pacaráima (212...

A list of the birds recorded from Bangka Island, Indonesia Naturalis
Mees, G.F..
An enumeration of bird specimens from Bangka present in museum-collections, has resulted in a faunal list of 172 species (176 forms). A discussion is given of the zoogeography of the island, the avifauna of which is mainly Sumatran in its affinities, but with a distinct Bornean influence. In contradistinction to a previously-published opinion (de Schauensee, 1958), there is no recognizable Javanese element in the avifauna.

Abundance of two Dendrocincla woodcreepers (aves: Dendrocolaptidae) in relation to forest structure in Central Amazonia Acta Amazonica
Cintra,Renato; Maruoka,Adrianny Erika; Naka,Luciano Nicolas.
Few studies have been conducted to verify how the structure of the forest affects the occurence and abundance of neotropical birds. Our research was undertaken between January 2002 and July 2004 at the Reserva Ducke, near Manaus (02º55',03º01'S; 59º53',59º59'W) in central Amazonia, to verify how the forest structure affects the occurrence and abundance of two bird species: the Plain-brown Woodcreeper Dendrocincla fuliginosa and the White-chinned Woodcreeper Dendrocincla merula. Bird species occurrence was recorded using lines of 20 mist-nets (one sample unit), along 51 1-km transects distributed along 9 pararel 8 km trails covering an area of 6400 ha. Along these transects, we placed 50 x 50m plots where we recorded forest structure components (tree...

Agroforestry system as a buffer zone in a Brazilian Atlantic Forest conservation unit: an artificial nest predation perspective Biota Neotropica
Galvão,Camila André; Francisco,Mercival Roberto; Schlindwein,Marcelo Nivert.
Abstract Here we inferred about the effectiveness of a buffer zone composed by an Agroforestry System (AS) for providing reproductive conditions for Atlantic Forest birds by comparing artificial nest predation rates between a buffer zone, a primary forest area, and a set of small and isolated Atlantic Forest fragments. We have used 237 nests throughout the three areas, of which 100 (42.2%) were depredated. Predation frequencies were 28.6% in the continuous forest, 100% in the AS, and 51.9% in the fragments, differing significantly. We could detect nest predators in 48 of the 100 depredated nests (48%) using camera traps. Differences between areas may be attributed to changes in nest predator species. We support previous evidences that the conservation of...

Altitudinal distribution of birds in a mountainous region in southeastern Brazil Rev. Bras. Zool.
Mallet-Rodrigues,Francisco; Parrini,Ricardo; Pimentel,Leonardo M. S.; Bessa,Rafael.
We studied the altitudinal distribution of 426 bird species in the Serra dos Órgãos, a mountainous region in southeastern Brazil. Thirty-four localities were visited between 1991 and 2009. Our study revealed a decline in bird species richness with elevation, although a smaller number of species was recorded at lower altitudes (below 300 m) possibly due to local extinctions caused by the intense human occupation of the region. A less diverse avifauna was found above 2,000 m, with only one species (Caprimulgus longirostris) recorded exclusively in this altitudinal range. Most endemic species were found between 300 and 1,200 m, but the endemism was more significant at higher altitudes. Nearly half of the birds found above 1,400 m were endemic species. Most of...

Analysis of growth curves in different lineages of Caipira broiler type Animal Sciences
Araujo, Caroliny Costa; Rodrigues, Kênia Ferreira; Vaz, Roberta Gomes Marçal Vieira; Conti, Ana Carolina Muller; Amorim, Aline Ferreira; Campos, Carla Fonseca Alves.
The objective of this work was to identify, by means of different statistical criteria the ideal nonlinear regression model to describe the growth curve of three lineages of caipira broiler for meat production. A total of 90 birds were used, being 30 birds from each of the following lineages: Pescoço Pelado, Carijó and Pesadão Vermelho. The individual body weight of broilers (1, 7, 14, 21,28, 35, 42, 49, 56, 63, 70, 77, 84 and 91 days of age) was collected weekly for determination of growth curves by means of Models von Bertalanffy, Gompertz, Logistic, Richards and Brody. The parameters of Brody model did not converge to the weight of strains. The model that better adjusted to the data was Logistic.

Are levels of digestive enzyme activity related to the natural diet in passerine birds? Biol. Res.
Ramírez-Otárola,Natalia; Sabat,Pablo.
Digestive capabilities, such as the rates nutrient hydrolysis and absorption, may affect energy intake and ultimately feeding behavior. In birds, a high diversity in gut biochemical capabilities seems to support the existence of a correlation between the morphology and physiology of the intestinal tract and chemical features of the natural diet. However, studies correlating the activity of digestive enzymes and the feeding habits at an evolutionary scale are scarce. We investigated the effect of dietary habits on the digestive physiological characteristics of eight species of passerine birds from Central Chile. The Order Passeriformes is a speciose group with a broad dietary spectrum that includes omnivorous, granivorous and insectivorous species. We...

Ascocotyle (Phagicola) rara sp. n. (Digenea, Heterophyidae) from Ixobrychus exilis (Aves, Ardeidae) in Brazil Zoologia
Arruda,Vanessa Santos de; Muniz-Pereira,Luís C.; Pinto,Roberto Magalhães.
Ascocotyle (Phagicola) rara sp. n. is described from the intestine of Ixobiyclius exilis (Gmelin, 1789), a Brazilian bittern. The new species is compared with Ascocotyle (Phagicola) angeloi Travassos, 1928 and Ascocotyle (Phagicola) moUieiiisicola (Sogandares-Bernal & Bridgman, 1960); the main distinguishing characters are related to the aspect of the gonotyl that is not perforated in A. (P.) rara sp. n. when compared to A. (P.) mollienisicola and the absence of the crown of spines at the anteriorend in the new species compared withA. (P.) angeloi. This is an important finding, since human infections by Phagicola spp. have been previously reported in Brazil.

AVES DE ISLA FUERTE Y TORTUGUILLA, DOS ISLAS DE LA PLATAFORMA CONTINENTAL DEL CARIBE COLOMBIANO Boletín de Investigaciones
Estela,Felipe A..
Bird observations were made during five days between 2004 and 2006 on Isla Fuerte and Isla Tortuguilla, two continental shelf islands of the Colombian Caribbean coast. On both sites 83 species were recorded. Isla Fuerte is larger and has a more complex array of habitats, supporting a larger and more complete bird community. Noteworthy species and aspects on the conservation of these insular environments are discussed.

Aves de três remanescentes florestais do norte do Estado do Paraná, sul do Brasil, com sugestões para a conservação e manejo Zoologia
Bornschein,Marcos Ricardo; Reinert,Bianca Luiza.
One hundred eighty species in a preliminary inventory were identified. From these, 166 were in an area of 832.5 ha (Mata São Francisco State Park), 84 in another of 9.7 ha (Manoel Júlio de Almeida Municipal Forest) and 99 in the third remnant, briefly sampled, of 218 ha (Mata São Paulo). Comparing these numbers to inventories of nearby sites was considered that the larger area is poor in number of bird species, and believe this to be mainly due to the high degree of environmental degradation. Was considered that the smaller area is rich in birds, but its proximity (375 meters) to the third remnant certainly exeits strong influence. This paper presents the list of birds by site and with their relative frequency of occurrence. A new record for Paraná...

Collisions between aircraft and birds, so-called “bird strikes,” can result in serious damage to aircraft and even in the loss of lives. Information about the distribution of birds in the air and on the ground can be used to reduce the risk of bird strikes and their impact on operations en route and in and around air fields. Although a wealth of bird distribution and density data is collected by numerous organizations, these data are not readily available nor interpretable by aviation. This paper presents two national efforts, one in the Netherlands and one in the United States, to develop bird avoidance nodels for aviation. These models integrate data and expert knowledge on bird distributions and migratory behavior to provide hazard...

Behaviour of cockatiels (Nymphicus hollandicus) at two temperatures in captivity Arq. Bras. Med. Vet. Zootec.
Carvalho,T.S.G.; Zangeronimo,M.G.; Saad,C.E.P.; Alvarenga,R.R.; Assis,V.D.L.; Pereira,V.M.; Scalon,J.D.; Silva,J.P..
Behavioural studies with cockatiels (Nymphicus hollandicus) in captivity are scarce. Due to the need for appropriate management of these animals, this study was performed to examine the behaviour of cockatiels kept in captivity at two temperatures. Sixteen cockatiels were individually housed in cages (62cm high x 43cm long x 27cm wide) and fed with a commercial ration and seed mixture for psittacids. Water was provided ad libitum. The eight-day experiment was divided into two stages of four days each. In the first stage, the birds were kept at room temperature (25°C) with 70% relative humidity during 24 hours. In the next stage, they were kept at 35°C from 06:00 to 18:00h and 25°C from 18:00 to 06:00h, also at 70% relative humidity. The behaviour of the...

Bird community as an indicator of biodiversity: results from quantitative surveys in Brazil Anais da ABC (AABC)
VIELLIARD,JACQUES M. E..
This short review presents the results obtained in several localities of Brazil on the composition of forest bird communities. Data were collected since the late 80's, after we introduced a new methodology of quantitative survey, based on acoustic identification and unlimited-radius point census. Although these data are still scattered, they show uniquely precise and coherently comparative patterns of composition of forest bird communities. Our methodology has the advantage of being absolutely non-disturbing, highly efficient in the field and immediately processed. Results confirm that the structure of a bird community is a good indicator of biodiversity, particularly useful where biodiversity is high. Many of these data are available only in unpublished...

Birds in an Australian Rainforest: Their Attraction for Visitors and Visitor's Ecological Impacts AgEcon
Tisdell, Clement A.; Wilson, Clevo.
Lamington National Park in Queensland, Australia is noted for its rainforest and is part of the World Heritage listed property but prior to this work, no systematic study has been done of the importance of birds to its visitors. This study is based on data from survey forms handed to visitors at an important site in the park and completed by visitors following their visit. It yielded 622 useable responses. These enabled us to establish the comparative importance of birds as an attraction to this site for this sample of visitors. Furthermore, logit regression is used to target analysis and to identify factors that increase the likelihood of a visitor saying that birds are an important attraction. In addition, the relative importance to visitors of...
