Brazil has one of the highest avifauna diversities in the world, and many species are used by human populations in many different ways. Capturing wild birds for food, or to raise as pets, or for commercial purposes, together with the loss of habitat, have been the principal causes of population reductions among many species. The present work provides new information about the diversity of wild bird species used in Ceará State (Northeast Brazil) and the techniques used for capturing them, as well as the forces motivating this hunting, the commercial relationships involved, the maintenance of captive species, and the legal and conservation implications of the use of the regional avifauna. A total of 92 wild bird species belonging to 26 families were found to be used as food (39 spp.), for medicinal (3 spp.) and magic-religious (1 spp.) purposes, for commercial ends (46 spp.), or raised as pets (44 spp.), or killed to control their predation on domestic animals (5 spp.). Raising or selling birds is motivated by their singing and/or their natural beauty, with Thraupidae, Icteridae and Emberizidae being the principal families sought after for those purposes. The Family Columbidae has the greatest importance as a food source. Eleven traditional capture techniques (both active and passive) were identified. The commercial value of the birds varied depending on both intra-and inter-specific factors, and the trade in these animals involved both dealers who sold large numbers of individuals at low prices and specialists (''passarinheiros'') who sold just a few domesticated individuals of greater value. Our evaluations of transactions taking place in public markets indicated the probable over-exploitation of a number of species, and these were often imported from other states and countries. In addition to being illegal, the capture of wild birds can cause serious environmental problems that can only be addressed through public policies directed towards education, monitoring and control, alternative sources of income, wildlife management, and ecosystem conservation.
Abstract:Baturité Ridge is an important Atlantic Forest remnant inserted in the Caatinga Morphoclimatic Domain located in the Ceará state, Northeast Brazil. Al though this area presents high rates of endemism and has been investigated by many researchers in the past, there was never an investigation regarding local mammals. In this context, this study aims to survey the non-volant mammals of this region to serve as a basis for future ecological and conservation studies. The work was conducted between 2009 and 2014, based on analyses of voucher specimens from zoological collections, capture of specimens in fieldwork, visual and photographic records, and interviews with selected local residents. Altogether, 32 species were documented and seven are present on lists of endangered animals. In addition, interviews indicated that three non-recorded species probably occur in the area and another two were pointed out by local people as locally extinct. Discussions about identification and conservation aspects were presented.
