Lopes el al. • DISTRIBUTION OF BLACKISH-BLUE SEEDEATER 
801 
plots, which revealed no seasonal concentration of 
records in some areas of the plot. We found no 
evidence of regular movements between the 
Atlantic Forest and the Cerrado. Records of 
Blackish-blue Seedealers in the Cerrado are from 
January. February, March. April, July, August, 
September, and October (Hellmayr 1929, Silva 
1995b, Pacheco et al. 2007, this study ). 
Blackish-blue Seedeaters have been recorded 
throughout the year in Misiones. There arc. for 
example, specimens collected in every month of 
the year in Arroyo Uruguay-i, a well sampled 
locality. Differences in number of collected 
specimens in Misiones through the year are 
probably attributable to collecting efforts, as 
demonstrated by the positive correlation between 
numbers of collected specimens of Buff-fronted 
Poliage-gleaners and Blackish-blue Seedeaters 
tSpearman Rank Order Correlation; // = 12, R 
= 0.63, P = 0.03). Data available for Brazil are 
scarce, and does not allow a similar analysis. 
However, in the State of ParantL which provides 
the majority of Brazilian records, there are records 
for all months of the year, except December. We 
cannot reject the hypothesis of nomadic move¬ 
ments with the data available, but we found no 
evidence of regular large scale or local move¬ 
ments, suggesting this species is a year-round 
resident, at least in Argentina. 
ACKNOWLEDG M ENTS 
LEL benefited from a doctoral fellowship from FAPE- 
MIG during part of this study. Our field work was 
su Pportcd by grants from Nticlco de Estudos Ecolrigicos 
Pantanal, Centro de Pesquisa do Pantanal. Instituto 
Nacional de Areas Umidas, and MinistSrio da CiSncja e 
Teenologia. Visits to North American museums were made 
possible through a Collection Study Grant received by LEL 
irom AMNH. Luciano Arruda allowed our study in Cticeres 
■*nd provided logistic support. Pedro Viana kindly identified 
bamboo species, and Guilherme Freitas compared 
DZLFMG specimens with others housed in MNRJ. We 
'hank IBAMA for providing a collection permit (14496-1).

museums kindly made available on-line data on specimens 
housed in their collections at the SpeciesLink <bttp://splink. 
cria.org.br/) or at the ORNIS (http://ornisnet.org) portals: 
LACM, (JMMZ, FMNH, and 1AL. I.uiz Gonzaga sent data 
on tape recordings deposited in the sound archive under his 
care (ASEC), as well as a compilation of records of this 
species. XC (http://www.xeno-canto.org) and ML (http:// 
rnacaulaylibrary.org/index.do) kindly made available on¬ 
line their sound archives. C. E. Braun, Peter Vickery, Gary
