As aves da Esta？？o Ecológica Serra Geral do Tocantins, Centro do Brasil

the esta？？o ecológica serra geral do tocantins is one of the largest conservation units in cerrado biome. the avifauna of this locality was studied from january 25 to 15 february, 2008. we attempted to sample the different habitats found both within the eesgt as in its surroundings. in addition to audio and visual records, mist nets and shotguns were used to collect testimony material, which was deposited in the ornithological collection of the museu de zoologia da universidade de s？o paulo (mzusp). the results were compared with data available from other conservation units nearby the eesgt. we recorded 254 bird species; among these 11 were considered endemic to the cerrado region and other three considered threatened (taoniscus nanus, anodorhynchus hyacinthinus and procnias averano). three individuals belonging to the picumnus genus also were collected; they presented unusual plumage and vocalization patterns, which suggests an undescribed taxon.
