ABSTRACT. The Pernambuco Center of Endemism (PCE) in northeastern Brazil is highly fragmented and degraded. Despite its potential conservation importance the bird fauna in this area is still relatively unknown and there are many remnant fragments that have not been systematically surveyed. Here, we report the results of bird surveys in five forest fragments (one pioneer, two ombrophilous and two seasonal). In total, 162 taxa were recorded, 12 of which are endemic to the PCE. The frequency of endangered species was lower than what has been reported in studies from the same area and most of the taxa considered to be at risk of extinction were sub-species of uncertain taxonomic validity. The comparatively low number of endemic/threatened species may be due to the small size of the fragments in the present study -a consequence of the high levels of habitat loss in this region. Analysis of species richness patterns indicates that ombrophilous forest fragments are acting as refuges for those bird species that are most sensitive to environmental degradation. KEYWORDS.Avifauna, ombrophilous forest, restinga, seasonal forest, species richness. RESUMO. Comunidade de aves em três tipos florestais no Centro de Endemismo Pernambuco. O Centro de Endemismo Pernambuco(PCE), a área de Floresta Atlântica ao norte do rio São Francisco no nordeste do Brasil é altamente fragmentado e degradado. Apesar de sua importância nacional e global, a avifauna desta área é relativamente pouco estudada e há muitos fragmentos remanescentes que não foram sistematicamente pesquisados. Aqui, nós relatamos os resultados de pesquisas com a avifauna de cinco fragmentos florestais (um de floresta pioneira, dois de floresta ombrófila e dois de floresta sazonal). No total, 162 taxa foram registrados, 12 dos quais são endêmicos do PCE. No geral a frequência de espécies ameaçadas foi mais baixa do que em estudos similares e a maioria dos taxa considerados em risco de extinção foram subespécies de validade taxonômica incerta. Os principais fatores desse contraste podem ser o tamanho relativamente pequeno dos fragmentos do presente estudo e o elevado nível de fragmentação e degradação do habitat. A análise do padrão de riqueza de espécies pode indicar que os fragmentos de floresta ombrófila estão atuando como refúgio importante para espécies de aves que são sensíveis à degradação ambiental.

“…Although selective logging severely disturbs certain species within the forest, other species can quickly recover and continue to maintain viable populations. Top carnivores, such as large cats, 110 appear to be maintained in logged forest in the absence of hunting (Johns, 1985).…”

The clouded leopard Neofelis nebulosa has already disappeared from part of its range in southern Asia; it is classified as vulnerable by IUCN and is on Appendix I of CITES. Little is known about this secretive forest-dweller anywhere in its range, and the sparse information needs to be augmented so that effective conservation measures may be taken if necessary. In early 1986 the senior author travelled through the interior of Malaysian Borneo, staying at villages and timber camps, to assess the status of the species in the region and to find out more about its behaviour.

“…Extrapolating from estimates of density and geographic range, the total effective population size (Borneo and Sumatra) of the Sunda clouded leopard has been estimated at <10 000 individuals, and no sub-population is thought to contain >1000 individuals (IUCN 2008). The clouded leopard may be a complementary flagship and umbrella species to the apes, as they may persist at lower densities, require larger areas of habitat and a sufficient prey base (Johns 1985, 1988, Burnham et al 2013.…”
