    Full Text Available During a survey for ectoparasites on birds in a small reserve of the Brazilian cerrado (savannah a male adult Rhipicephalus sanguineus tick was found attached to the eyelid of the bird Coereba flaveola. Both tick and bird are presently common in Brazil, however, to best of our knowledge, the association of this tick species with this bird species has not been reported before. This observation may be an accidental finding but might also be an unknown route for the dissemination of the tick. The species R. sanguineus was introduced in the country with the colonization and should be considered a research target for the surveillance of tick-borne diseases.Durante um levantamento sobre ectoparasitos em aves, em uma pequena reserva de cerrado, constatou-se um macho adulto do carrapato Rhipicephalus sanguineus fixado à pálpebra da ave Coereba flaveola. Embora a ave e o parasito sejam abundantes no Brasil, esta associação hospedeiro-parasita não foi previamente relatada. Esta observação pode se referir a um fato isolado e acidental, mas também pode se referir a uma via de disseminação antes desconhecida desta espécie de carrapato. A espécie R. sanguineus foi introduzida no Brasil durante a colonização e deve ser considerada um alvo de pesquisas importante na supervisão de doenças transmitidas por carrapatos.

    Full Text Available Ecotourism encourages an environmentally friendly exploration of the world's natural habitats. Tourists often engage in wildlife photography, an activity that is generally not considered disturbing to animals. We investigated the effects of camera-related stimuli to determine whether shutter noise and/or flash affected the immediate behavior of female crested anoles Anolis cristaellus. Anoles decreased their display rate following stimuli that included shutter noises, but did not change their behavior in response to flash or silence treatments. To determine the relative importance of this response, we observed anole behavior following playbacks of calls from kestrels Falco sparverius, a predator, and bananaquits Coereba flaveola, a non-predator. Anoles decreased display rates following kestrel calls when compared to their response to bananaquit calls. Furthermore, anoles spent a greater proportion of time displaying following bananaquit calls compared to both kestrel calls and silence. The magnitude of response to shutter noises was about the same as that to predator calls. This demonstrates that photography may not be as benign as commonly believed, and we should consider whether restrictions on camera noises should be implemented to reduce animal disturbance [Current Zoology 57 (1: 77–82, 2011].

    Full Text Available Birds play crucial role on the pollination of many plants. However, little is known about the interactions between nectarivorous neotropical birds and exotic Angiosperms. S. nilotica is an exotic African plant widely used in Brazilian urban landscaping. However, it has been poorly studied in relation to its interactions with Neotropical birds. In this way, we studied the feeding nectar strategies and the interspecific antagonistic behaviours among nectarivorous Neotropical birds to verify the bird contributions to the S. nilotica pollination. The study was conducted from May 2008 to April 2011, but only in months of S. nilotica flowering (April to May. From 148 hours of sampling we identified 16 species feeding nectar on S. nilotica: 13 hummingbirds (Trochilidae, Aratinga aurea (Psittacidae, Tangara palmarum (Thraupidae and Coereba flaveola (Coerebidae. Eupetomena macroura was the most frequent (96.88%, followed by Chlorostilbon lucidus (78.13% and Coereba flaveola (59.38%. Most birds obtained nectar by punching at the base of the corolla, except for A. aurea that obtained the nectar by the upper opening of the petals in 100% of its visits, Heliomaster furcifer (95.65%, F. fusca (95% and A. nigricollis (70.27%. Despite E. macroura also obtains nectar only by punching at the base of the corolla, it showed the highest level of legitimate visits. Antagonistic events were more frequent in E. macroura (58.65%, Florisuga fusca (11.04% and Amazilia fimbriata (10.87%, being E. macroura dominant in all events. These results showed E. macroura plays an important role on this plant being the most important bird as a potential pollinator. Moreover, other birds contribute partially to the S. nilotica pollination. Most probably it is a result of recent Neotropical bird interactions with this African plant.

    Full Text Available This work studied the phenology and biology of the pollination of C. brasiliensis in an area of its natural occurrence (Pocinhos – PB. Fifteen plants were marked and observed every two weeks for the study of phenology. For the study of floral biology and morphology, flowers and inflorescences were marked and observed until fruit appeared. Visitors to flowers were observed throughout the experiment, and the frequency, time and behavior of their visits was registered. Canavalia brasiliensis demonstrated a pattern of annual flowering which was continuous, of long duration, with periods of greater flowering activity in the dry season. The inflorescence is of the paniculatum type, with flowers whose attributes are related to the syndrome of melittophily. Anthesis occurs during the day, beginning at 05h00. Nectar is produced from the phase of pre-anthesis, with a concentration of sugars around 44-60%. Visits by bees (Xylocopa frontalis, X. suspecta and X. sp., Apis mellifera and Centris similis and birds (Phaethornis ruber, Chlorostilbon aureoventris, Eupetomena macroura and Coereba flaveola were observed. Xylocopa frontalis acted as an effective pollinator.

    Full Text Available Inspite of Etythrina species exhibit morphologic attributes for adaptation to pollination by nectarivorous birds mentioned in the literature, E. speciosa is pollinated by lots of bees (Apinae and Meliponinae which show a great urban occurrence. Systems of E. speciosa floral reproduction, fenology, diversity, frequency and constancy of insects visiting at different hours and flowering periods were studied. E. speciosa is Biocompatible, but xenogamy is the predominant system of reproduction. A large diversity of insects visiting the inflorescences was observed, with predominance of bees. The bee species showed a higher frequency: Apis mellifera Linnaeus, 1758 (45,0 %, Trigona spinipes (Fabricius, 1793 (28,6%, Trigona hyalinata (Lepeletier, 1836 (12,2 % and the ant Zacryptoceruspusillus Klug, 1824 (2,8 %.

    Full Text Available The development of urban areas results in changes of natural landscapes, including the creation of several artificial environments. Thus, many animals find new opportunities for survival in these areas. This study aimed to obtain information about the richness, composition, and frequency of occurrence of the trophic guilds of an urban avian community in Ipatinga city, Minas Gerais State, followed by a general description. Between August 2005 and July 2006, 81 days were spent in sampling. From the method of direct observation, 57 species were recorded. The richness estimate for the area was 74.86 species (Chao2. The number of species between rainy and dry periods did not differ (p>0.05. Trophic guilds remained with a ratio of relatively similar species throughout the year, with a predominance of the omnivores and insectivores. Species such as Pitangus sulphuratus, Furnarius rufus and Sicalis flaveola were favored in the open areas. Two exotic species, Columba livia and Passer domesticus, were abundant. These results emphasize the necessity of the existence of natural areas within the urban context, considering not only the protection of the wildlife, but also the improvement of the quality of life in the cities.

    The aim of this study was to determine the prevalence of Cryptosporidium species and genotypes in birds kept in captivity in Brazil. A total of 966 samples from 18 families of birds was collected and stored in 5% potassium dichromate solution at 4 degrees C until processing. Oocysts were purified in Sheather sugar solution following extraction of genomic DNA. Molecular analyses were performed using nested-PCR for amplification of fragments of the 18S subunit of rRNA gene and of the actin gene. Amplification of Cryptosporidium DNA fragments was obtained in 47 (4.86%) samples. Sequencing of amplified fragments and phylogenetic analyses allowed the identification of Cryptosporidium baileyi in a black vulture (Coragyps atratus), a domestic chicken (Gallus gallus domesticus) and a saffron finch (Sicalis flaveola); Cryptosporidium galli in canaries (Serinus canaria), a cockatiel (Nymphicus hollandicus) and lesser seed-finches (Oryzoborus angolensis); Cryptosporidium meleagridis in a domestic chicken (G. g. domesticus); Cryptosporidium parvum in a cockatiel (N. hollandicus); Cryptosporidium avian genotype I in a canary (S. canaria) and an Indian peafowl (Pavo cristatus); Cryptosporidium avian genotype II in ostriches (Struthio camelus) and Cryptosporidium avian genotype III in a cockatiel (N. hollandicus) and a peach-faced lovebird (Agapornis roseicolis).

  14. SURVEILLANCE FOR NEWCASTLE DISEASE VIRUS, AVIAN INFLUENZA VIRUS AND MYCOPLASMA GALLISEPTICUM IN WILD BIRDS NEAR COMMERCIAL POULTRY FARMS SURROUNDED BY ATLANTIC RAINFOREST REMNANTS, SOUTHEASTERN BRAZIL

    Directory of Open Access Journals (Sweden)

    MB Guimarães

    Full Text Available ABSTRACT The geographic overlap between areas of Atlantic rainforest and human activities allows interactions to occur between humans and wild and domestic animals. Despite the great importance of the domestic animal-wildlife-human interface that occurs at poultry farms in terms of public health, economic production and wildlife conservation, there are few studies in Brazil examining the distribution and health of wild birds that interact with poultry farms. From January to December 2010, mist nets were used to capture 166 free-ranging birds that were within close proximity to three poultry farms in Atlantic rainforest remnants in south-eastern Brazil. The species composition was examined, and molecular methods were used to test for avian influenza virus, Newcastle disease virus, and Mycoplasma gallisepticum. The avian communities near the poultry farms were dominated by three synanthropic species, which corresponded to 70% of all captured individuals: house sparrows Passer domesticus (33%, saffron finches (Sicalis flaveola (22%, and ruddy ground-doves (Columbina talpacoti (15%. These predominant bird species were in poor body condition (27%, were infested with feather mites (43%, or presented both conditions (23%. No evidence of infection by avian influenza virus, Newcastle disease virus or M. gallisepticum was identified in any of the studied birds. Although no evidence of the studied pathogens was, our findings demonstrate that differences in the environmental characteristics and biosecurity practices influence the wild bird community near poultry farms, which in turn may affect the health status of these synanthropic birds and strengthen their role in the transmission of pathogens.

  15. Ethno-ornithology and conservation of wild birds in the semi-arid Caatinga of northeastern Brazil

    2013-01-01

    The utilization of birds as pets has been recognized as one of the principal threats to global avifauna. Most of the information about the use and sale of birds as pets has been limited to areas of high biodiversity and whose impacts of anthropic actions have been widely broadcast internationally, for example for the Amazon Forest and forest remnants of Southeast Asia. The Caatinga predominates in the semi-arid region of Brazil, and is one of the semi-arid biomes with the greatest biological diversity in the world, where 511 species of birds exist. Many of these birds are used as pets, a common practice in the region, which has important conservationist implications but has been little studied. Therefore, the aim of the present study was to detail aspects of the use of birds as pets in a locality in the semi-arid region of Northeast Brazil. Information on the use of avifauna was obtained through interviews and visits to the homes of 78 wild bird keepers. A total of 41 species of birds were recorded, mostly of the families Emberizidae (n = 9 species), Columbidae (n = 7 species), Icteridae (n = 6 species) and Psittacidae (n = 3 species). The birds that were most often recorded were Paroaria dominicana (n = 79 especimens), Sporophila albogularis (n = 67), Aratinga cactorum (n = 49), Sporophila lineola (n = 36), Sicalis flaveola (n = 29) and Sporophila nigricollis (n = 27). The use of wild birds in the area studied, as an example of what occurs in other places in the semi-arid Northeast, demonstrates that such activities persist in the region, in spite of being illegal, and have been happening in clandestine or semi-clandestine manner. No statistically significant correlation were found between socioeconomic factors and keeping birds as pets reflects the cultural importance of this practice of rearing wild birds for pets in the region, which is widespread among the local population, independent of socioeconomic factors. Obviously
