We present new records that augment, confirm or document our knowledge of the avifauna of the Araguaia Valley in central Brazil, including various first records for the states of Goias (e.g. Mississippi Kite lctinia mississippiensis, Sanderling Calidris alba, Fasciated Antshrike Cymbilaimus lineatus, Bobolink Dolichonyx oryzivorus), Mato Grosso (Dwarf Tinamou Taoniscus nanus, Scarlet-throated Tanager Compsothraupis loricata), Para (C. loricata) and Tocantins (e.g., Yellow-billed Cuckoo Coccyzus americanus, Pale-rumped Swift Chaetura egregia). We also report the first records for the state of Amazonas of Rusty-collared Seedeater Sporophila collaris and White-browed Blackbird Sturnella superciliaris. Other records improve our knowledge of the distribution of principally Amazonian species in the Cerrado biome or that of comparatively widespread species whose ranges have been consistently under-estimated in the standard literature on Neotropical birds, e.g., Whistling Heron Syrigma sibilatrix and Saffron Finch Sicalis flaveola. Our field work has also improved knowledge of the distribution and current status of certain Near Threatened (e.g., Chestnut-bellied Guan Penelope ochrogaster and Rufous-rumped Seedeater Sporophila hypochroma) and globally threatened species (e.g. two Sporophila seedeaters, and Kaempfer's Woodpecker Celeus obrieni). Additionally, we comment on the natural history and taxonomy of some poorly known species, e.g. Riverside Tyrant Knipolegus orenocensis xinguensis and Cone-billedTanager Conothraupis mesoleuca.
