“…Our finding that the majority of parrots leave the roost site before sunrise is in agreement with the results of Rocha et al (1988) for a mixed roost of five parrot species leaving to spend the daylight hours in Terra firme forest. However, our data contrast with those of Harms and Eberhard (2003), who found that Aratinga pertinax individuals left the roost site after sunrise.…”

“…However, we have no data of relevance to this hypothesis. The return from the roost site to Terra firme forest is presumably related to inadequate food supplies for the high number of parrots at the roost (Rocha et al 1988).…”

“…Among birds, some parrots had been studied in relation to their daily roosting behaviour (Rocha et al 1988, Mabb 1997, Harms and Eberhard 2003, Cougill and Marsden 2004. However, the factors influencing the time of arrival and departure of parrots in roosts are still little known (Sick 1997).…”

Environmental stimuli exert important effects on the expression of the endogenous rhythms. Daily movements of groups of parrots in response to the light/dark cycle have been studied by several researchers. However, the factors modifying the intrinsic rhythmicity of this behaviour remain little known. This study describes how the nychthemeral/circadian periodicity of roost daily movements of the Orange-winged Amazon Amazona amazonica is modified by weather factors. Numbers of parrots arriving or leaving the roosting site Ilha dos Papagaios were determined on a minute by minute basis. More parrots have significantly arrived at the roost after sunset than before, while more parrots have significantly left the roost before sunrise than after. The peak exodus of parrots occurred at 23 ± 5.24 minutes before sunrise, when the average light intensity was 1 lux. The peak influx of parrots occurred at 6 ± 6.1 minutes after sunset, when the average light intensity was 50 lux. By altering ambient light intensity, weather conditions have significantly influenced the arrival and departure times, with parrots leaving later and arriving earlier when conditions were overcast at the roost site.

ABSTRACT. Fifty-six villages along the coast of the State of Paraíba, Brazil, were visited to determine and map the occurrence of Amazona amazonica (Linnaeus, 1766). Search was conducted with binoculars and the residents of each locality were interviewed using a questionnaire to obtain information about the occurrence and species´s biological data. Reports of recent and old occurrences, absence and feeding areas were registered. The food items mentioned were fruits, such as cashew, cashew nuts, palm oil, and agricultural products, such as corn. The reproductive period occurred between November and December. Breeding sites were mangrove areas and coconut trees, with nests being made in tree hollows. Questionnaires helped to elaborate a distribution map of the species, in which the actual distribution was based on visual records, whilst the potential distribution of the species was based on the questionnaire answers. Furthermore, they provided an overview of the biology of the species in agreement with that reported in the literature. Current data may be used in future studies on the conservation of the species in the State of Paraíba.Keywords: conservation, curica, distribution map, questionnaires, reproduction.Distribuição do papagaio-do-mangue Amazona amazonica (Linnaeus, 1766) (Aves, Psittacidae) na região costeira do Estado da Paraíba, Brasil RESUMO. Cinquenta e seis localidades foram visitadas ao longo da região costeira da Paraíba visando conhecer a distribuição de papagaio-do-mangue (Linnaeus, 1766) nessa região do Estado. Foram realizadas buscas ativas com auxílio de binóculos e aplicado um questionário aos moradores de cada localidade com perguntas sobre a ocorrência e dados biológicos da espécie. Foram discriminados relatos de ocorrência recente, antiga, ausência e áreas de alimentação. Os itens alimentares citados foram frutas como caju, castanha do caju, dendê, e produtos agrícolas como o milho verde. A época reprodutiva foi descrita entre os meses de novembro e dezembro. Locais de reprodução foram áreas de manguezal e coqueirais, com os ninhos sendo feitos em ocos de árvores. Os questionários possibilitaram a elaboração de um mapa de distribuição da espécie, com a distribuição real sendo aquela baseada em registros visuais e a distribuição potencial da espécie aquela baseada nos relatos; assim como a formação de um panorama geral da biologia da espécie, estando estes de acordo com a literatura. Os dados obtidos neste trabalho podem servir de subsídio para futuros trabalhos conservacionistas com a espécie no Estado.Palavras-chave: conservação, curica, mapa de distribuição, questionários, reprodução.
