Aves da marujada: a ultilização de penas na confeccão do chapéu da maruja
(Universidade Federal do Pará, 2017-05) SANTOS, Ana Mabell Seixas Alves
This work aims to understand the use of bird feathers as fundamental raw material for the confection of the maruja hat in Bragança-PA, emphasizing the relationship between the artisans who produce the hats and the animals chosen para for this purpose. The preference for a species of duck, which resulted in the gradual disuse of other birds – such as guarás, herons and hens –, follows practical and aesthetic criteria that has affected the productive chain of the hat over the years. The obtaining and sacrifice of birds, as well as the choice and withdrawal of the feathers and the subsequent treatment necessary to their durability are marked by a relationship that reveals nuances of animating and different ways of dealing with religiosity. The duality between the human and non-human elements results in the materialization of the craft knowledge and in the experience of an occupation sometimes described as devotional. The work was developed based on fieldwork, with interviews to five artisans, and in the bibliographical research about material culture, from which is possible to highlight Miller (2010) and Hall (2003).

A first evaluation on the use of Ardea albus feathers as bioindicators of mercury burden in Amazonian ecosystems
(Instituto Nacional de Pesquisas da Amazônia, 2009) GOMES, Andreza de Lourdes Souza; 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.
