122 Notes on the breeding ecology and seasonality of some Brazilian birdsGuy M. Kirwancollated in general reference works. Few efforts have beenmade to uncover all available data for the species includedhere, but most readily available sources of informationhave been covered.Species AccountsGrey Tinamou Tinamus taoI was shown a recently abandoned nest of this species,containing three greenish-blue large spherical eggs,at Cristalino Jungle Lodge, northern Mato Grosso, on 17August 2007. The nest and eggs matched descriptions inthe literature (Davies 2002).Brown Tinamou Crypturellus obsoletusAn adult with a small young, probably just a few daysold, and still in down, were observed on a road withinParque Estadual Intervales, São Paulo, on 28 November2008. Little has been published concerning breeding season:Cabot (1992) mentioned September to Novemberin southeast Brazil, and Davies (2002) repeated the same,as well as October in southeast Peru. Basic informationon clutch size and incubation period are also available(Euler 1900, Davies 2002); whether the single young observedat Intervales was really the only surviving memberof the clutch cannot be determined.Bare-faced Curassow Crax fasciolataTogether with H. Shirihai, I observed a pair with asingle small young (sexed as a female, based on the whitetippedcrest) in tall gallery forest on the north bank of therio Pixaim, in the Pantanal of Mato Grosso, on 3 November2006 (Figure 1). At Emas National Park, Goiás, on 22December 2008, I observed a pair with two similar-sizedyoung, one obviously male based on the largely blackplumage and yellow bill, and the other female; generallythe male young closely followed the adult male and theyoung female stayed close to the adult female. Despitethis curassow’s comparatively wide distribution and relativeabundance, published breeding data are surprisinglyfew, as already noted by del Hoyo and Motis (2004) andBruno et al. (2006).Ash-throated Crake Porzana albicollisOn 1 February 2002, together with D. Beadle, A.Grosset and J.C. Minns, in the Serra dos Carajás, Pará,our local guide, Joraci José Grigilo, caught a small chick,presumably of this species, on a grassy slope adjacent toa dirt road within a mosaic of forest and grassland. Thechick was c. 7 cm in total length. Most of the down onthe underparts, head and nape was buffy-brown, but withan obvious pale grey-white chin and upper throat, muchdarker area around the eye and line of very dark feathersfrom the bill, over the centre of the crown to the mantle.Figure 1: Family of Bare-faced Curassows Crax fasciolata, rio Pixaim, Pantanal, Mato Grosso, November 2006 (Hadoram Shirihai).Revista Brasileira de Ornitologia, 17(2), 2009
