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.

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...

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.

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...

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...

Bryophytes as a material to build birds’ nests in Brazil Boletín de la Sociedad
De Almeida Amélio,Leandro; Marchi Do Carmo,Dimas; Soares De Lima,Jéssica; Fernandes Peralta,Denilson.
Birds’ nests are elaborate constructions that are built to provide a safe and secure environment for the eggs and hatchlings of birds to develop. Twigs and leaves represent common nesting materials in birds’ nests globally and with their beaks, they can carry materials, sometimes larger than the birds themselves, to construct their nests. In addition to twigs and leaves, birds also use various other materials less frequently, such as bryophytes, and in this study we examined the prevalence of bryophytes in birds’ nests in Brazil. We analyzed the nest composition of 21 birds’ nests from the Brazilian bryophyte collection at the Institute of Botany (SP Herbarium) and found that bryophytes were a widely used nesting...

COLOMBIAN FROZEN BIODIVERSITY: 16 YEARS OF THE TISSUE COLLECTION OF THE HUMBOLDT INSTITUTE Acta biol.Colomb.
ARBELÁEZ-CORTÉS,Enrique; TORRES,María Fernanda; LÓPEZ-ÁLVAREZ,Diana; PALACIO-MEJÍA,Juan Diego; MENDOZA,Ángela María; MEDINA,Claudia Alejandra.
Collections of frozen tissue samples stand as keystone sources of molecular information to construct biodiversity knowledge, and are particularly challenged if they focus on megadiverse countries. In 1998 the Humboldt Institute (Instituto de Investigación de Recursos Biológicos Alexander von Humboldt) began a tissue collection of Colombian biodiversity (IAvH-CT) and the aim of this work is to present a diagnostic and an historical perspective for that collection, constructed by compiling information and experiences on its management as well as by organizing and curating the information of each catalogued sample. After 16 years, the IAvH-CT harbors 16,469 samples, which represent around 2530 species from 1289 genera, and 323 families of the Colombian...

Comportamento alimentar de aves em Alchornea glandulosa (Euphorbiaceae) em Rio Claro, São Paulo Iheringia, Sér. Zool.
Valente,Renata de Melo.
Fourteen bird species were observed visiting one specimen of Alchornea glandulosa Poepp., 1845, at the Horto Florestal Navarro de Andrade, Rio Claro, São Paulo State, Brazil. Among them, three species seem to be the most efficient seed dispersers of A. glandulosa at the study site: Myiodinastes maculatus (Müller, 1776), Empidonomus varius (Vieillot, 1818) e Tyrannus melancholicus Vieillot, 1819. Besides to swallow fruit whole, these birds contributed with 68.5% of the total feeding visits. A. glandulosa fruit are not the mainly part of the diet of any one of the observed bird species, since they do not fit in the frugivorous specialized category. However, as almost all the observed individuals swallow fruit whole, it is suppose that they promote an...

Dawn chorus variation in East-Asian tropical montane forest birds and its ecological and morphological correlates Naturalis
Chen, W.-M.; Lee , Y.-F.; Tsai, C.-F.; Yao, C.-T.; Chen, Y.-H.; Li, S.-H.; Kuo, Y.-M..
Many birds in breeding seasons engage in vigorous dawn singing that often turns to a prominent chorus. We examined dawn chorus variation of avian assemblages in a tropical montane forest in Taiwan and tested the hypothesis that onset sequence is affected by eye sizes, foraging heights, and diet of birds. Chorus onset and duration varied between sampling months, but generally peaked in the prime breeding season. Overall dawn chorus length increased with, but mean duration per species was negatively correlated with, species richness. The inter-correlation among trait variables in phylogenetic independent contrasts was calculated and examined. Both foraging height and relative eye size were selected as positively explanatory factors, but no dietary effects...

Córdova Avalos, Antonio.
Se evaluó la salud de los Pantanos de Centla, Tabasco, mediante un índice de integridad biológica (IBI) utilizando a las aves como indicadoras. Se seleccionaron sitios de manglar y popal-tular con diferente grado de perturbación (conservado, semiconservado y perturbado). Un análisis de cambio de cobertura con imágenes de satélites Landsat MSS 1976 y ETM 2002 mostró pérdidas de cobertura de manglar de 21─31 % y tasas de deforestación anual de 0.8 ─ 1.2 %. El registro histórico de especies de aves fue de 328, detectándose 189 en este estudio, de las cuales 13 fueron nuevos registros para la Reserva. Se encontraron diferencias significativas en el número de especies entre sitios (α=0.05). De acuerdo con el estimador de cobertura basado en abundancias,...

Differential effects of habitat fragmentation on birds and mammals in Valdivian temperate rainforests RChHN
KELT,DOUGLAS A..
Four recent studies on Chilean vertebrates underscore the very different effects that habitat fragmentation may have under different conditions. In southern Chile, birds exhibited significant species-area relationships, whereas the more depauperate small mammal community did not. The avifauna of highly isolated rainforest remnants in Fray Jorge National Park (IV Región) presented steeper species-area relations than those in southern Chile, reminiscent of land-bridge islands after faunal relaxation. The small mammal results were unexpected but may reflect the reduced vagility and immigration potential of this group. Additionally, the inter-remnant matrix habitat may support large populations of only some species, allowing them to capitalize on resources...
