ABSTRACT
Local inhabitants retain a vast knowledge about the bird richness surrounding them, as well as many of their ethological and ecological aspects, and can identify the importance of those birds to the maintenance of ecosystem integrity. The present study sought to document the traditional knowledge retained by members of the Labino community concerning the avifauna of the Delta do Rio Parnaíba Environmental Protection Area (APA), Piauí State, Brazil. We interviewed 76 male (51% of the sample) and 74 female (49%) residents. The interviewees indicated the occurrence of 97 bird species belonging to 21 orders and 40 families. Men could identify more bird species than women. Older individuals recognize more bird species than younger members of the community. Individuals with less schooling demonstrated greater knowledge of species richness than those with more formal educations. A very significant percentage (45%, n = 68) of the interviewees reported consuming native birds, principally Aramides cajaneus, Columbina squammata, and Zenaida auriculata. A total of 48 species were perceived as having their populations reduced in recent years, principally Mimus gilvus, Icterus jamacaii, Aramides cajaneus, Turdus rufiventris, and Cacicus cela. The residents of the Labino community were therefore found to have a detailed knowledge of the local avifauna and perceived impacts caused mainly by hunting in the Parnaiba River Delta region.

Revista de Etologia (RE) is a Brazilian journal aimed at publishing scientific articles in the field of Ethology (Animal Behavior). Recently, RE was renamed to "Current Ethology", and some of its publishing policies were changed. A survey of the published articles in the journal while still named RE was carried out with the purpose of recognizing publication trends and patterns. The journal was regularly published during two periods: from 1998 to 2006 and from 2010 to 2014. Recent years have seen a reduction in the number of volumes published, but studies listed as "Observational" were prevalent in almost all volumes. Class "Mammalia" was the most studied taxon in the RE reports. Southeast Brazil has the highest number of empirical investigations and of publishing institutions. RE also contains publications from 12 countries. These trends are discussed taking into account the development of Ethology in Brazil and the current state of the country's biodiversity cataloging. The low number of studies on animal behavior in most regions of Brazil is pointed out and a suggestion for further research is mentioned
A Revista de Etologia (RE) é um periódico brasileiro destinado à publicação de artigos científicos no campo da Etologia (Comportamento Animal) em geral. Recentemente, a RE foi renomeada Current Ethology, e algumas de suas políticas de publicação foram alteradas. Neste trabalho foi feito o levantamento dos artigos no periódico ainda como RE com o objetivo de indicar tendências e padrões nos trabalhos publicados. Houve regularidade nas publicações em dois períodos: de 1998 a 2006, e de 2010 a 2014. Os anos recentes foram menos prolíficos, e estudos identificados como "Observacionais" predominaram em todos os volumes. A classe "Mammalia" foi o táxon mais estudado nos artigos da RE. Instituições da região Sudeste do Brasil foram responsáveis pelo maior número de publicações no periódico estudado. A RE contém artigos de 12 países. Essas tendências são discutidas levando-se em conta o desenvolvimento da Etologia no Brasil e o estado atual da catalogação da biodiversidade do país. O número reduzido de estudos sobre comportamento animal na maior parte das regiões do Brasil é apontado, e sugestões para pesquisas adicionais são fornecidas
