AbstractIllegal wildlife trade is one of the major threats to Neotropical psittacids, with nearly 28% of species targeted for the illegal pet trade. We analysed the most comprehensive data set on illegal wildlife trade currently available for Venezuela, from various sources, to provide a quantitative assessment of the magnitude, scope and detectability of the trade in psittacids at the national level. We calculated a specific offer index (SO) based on the frequency of which each species was offered for sale. Forty-seven species of psittacids were traded in Venezuela during 1981–2015, of which 17 were non-native. At least 641,675 individuals were traded, with an overall extraction rate of 18,334 individuals per year (35 years of accumulated reports). Amazona ochrocephala was the most frequently detected species (SO = 3.603), with the highest extraction rate (10,544 individuals per year), followed by Eupsittula pertinax (SO = 1.357) and Amazona amazonica (SO = 1.073). Amazona barbadensis, Ara ararauna and Ara chloropterus were the fourth most frequently detected species (SO = 0.564–0.615). Eleven species were involved principally in domestic trade (> 60% of records). Our approach could be the first step in developing a national monitoring programme to inform national policy on the trade in psittacids. Patterns and numbers provided may be used to update the official list of threatened species, and could also be used in planning conservation actions.

Amazona Amazonica

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.
