Epiphyte plants use by birds in Brazil

This study firstly reviewed the interspecific interaction records between birds and epiphyte plants in Brazil. Forty two documents, including articles, scientific notes, books and thesis, and 35 personal records and from collaborators were argued, totaling 112 species of birds that interacted with 97 species of epiphyte plants. Two articles treated the theme specifically and another 40 treated related subjects, such as: pollination of epiphytes, ecology and feeding behavior of birds. Studies were concentrated mainly in Atlantic Forest, in the southeastern Brazilian region. The epiphyte species more visited by birds was Aechmea nudicaulis (Bromeliaceae). The main visitor of epiphytes was Ramphodon naevius (Trochilidae). According to the number of authors' citations an index of generality in bird-epiphyte interactions was created. As result the index inferred that the ovenbird Cichlocolaptes leucophrus and the bromeliad Nidularium procerum are less generalist and more specialist species in bird-epiphyte interactions. The totality of the papers showed a considerable number of bird species that use the epiphytes plants and its resources, including nectar, fruits, invertebrates, nest material, nesting place, water and bath. Considering the importance of epiphytes to supply a variety of resources for birds, these results highlighted the necessity of additional and specific studies about the theme in various Brazilian regions and biomes.

Birds of a central São Paulo woodlot: 1. Censuses 1982-2000

Foram listadas 263 aves próximo e dentro de uma mata semidecídua de 230 ha em meio a plantações de cana-de-açúcar, na região central do Estado de São Paulo, Brasil. Subtraindo-se 67 espécies de áreas abertas, 22 de riachos, 10 vagantes e 12 observadas mais tarde, cerca de 152 espécies de mata e de borda foram observadas entre 1982-86, semelhantemente às observadas em uma mata próxima a Campinas. Ambas as matas perderam espécies gradualmente. Algumas aves evitaram as margens duras dos canaviais, preferindo as margens macias arbustivas. Das espécies de área aberta, parece que 22 desapareceram até 1997, em razão das abundantes chuvas anteriores causadas por El Niño, ou pela raridade de habitats permanentemente abertos nos canaviais; 17 espécies novas eram principalmente noturnas que não haviam sido checadas anteriormente, ou visitantes ocasionais. A mata e as bordas perderam 37 espécies, ganhando 5 de regiões secas e 1 visitante de inverno. Vários migrantes do sul apareceram somente em anos chuvosos antes do recente efeito estufa; algumas aves residentes foram caçadas, e os beija-flores das copas talvez estivessem presentes ainda. As espécies de zonas secas, prones à movimentação ou metapopulacionais, movem os centros de distribuição, camuflando parcialmente a perda de diversidade da mata úmida.

Feather mites of Brazil (Acari: Astigmata: Analgoidea and Pterolichoidea)

We present a checklist of feather mites known from native birds in Brazil. The list was compiled from a survey of Brazilian records published in indexing databases (e.g. Zoological Records) and from the available literature. To date, 185 nominal species representing 21 families have been recorded from Brazilian birds. Associations with 15 bird orders were found: Anseriformes, Apodiformes, Caprimulgiformes, Ciconiiformes, Columbiformes, Cuculiformes, Falconiformes, Galliformes, Gruiformes, Opisthocomiformes, Passeriformes, Piciformes, Psittaciformes, Tinamiformes and Trogoniformes. These birds sum to 218 species, which represent only 12.4% of all bird species occurring in Brazil. The feather mite fauna of several species-rich and important bird orders in Brazil remain unexplored, including Cathartiformes, Charadriiformes, Coraciiformes, Galbuliformes and Strigiformes. We estimate that between 900 and 5300 feather mite species are expected to occur on Brazilian birds, which is at least five times greater than current records. The training of researchers with expertise in the taxonomy of this group of mites should be stimulated so that there is a compatible number of taxonomists to discover and describe the almost unexplored feather mite fauna in Brazil.
