pastures and rice plantations (Luciano Arrudt 
pers. comm.). The area was abandoned -25 year 
ago, and is now covered by a dense stand of 3-n 
tall Giuidua bamboo, a common invasive specie 
in the region. This same bamboo stand producer

The range of Blackish-blue Seedeaters it 
puzzling with scattered occurrences in region' 
subject to several different climatic regimes 
elevation, and vegetation types. This species 
appears to be absent or rare in extensive areas ol 
apparently suitable habitat in southeastern Brazil 
the patchy distribution of Blackish-blue Seedeat- 
ers across the Cerrado may also be due to 
sampling effort, because -70% of it has not been 
sat.sfactor.ly sampled for birds (Silva 1995a). 
Particularly poorly sampled is the central-north 
and western portion, where extensive areas 
dominated by Guadua woody bamboos occur 
(Bystriakova et al. 2004: map 3.4). These regions 
are poorly sampled as demonstrated by several 
first reports of Kaempfer's Woodpecker t Celeus 
obrieni), a bamboo specialist, until quite recent!} 
known only from its type specimen collected in 
1926 (Domas et al. 2011). 
The Blackish-blue Seedeater seems to ^ 
common in its limited range in Argentina (Chebez 
2009). William Partridge collected more than l Jl1 
Blackish-blue Seedeaters in Misiones in the 1950 s 
(Partridge 1953. 1954). In contrast we located 
<50 skins of this specimen from throughout its 
range outside Misiones. 
We found no evidence of regular large scale 
movements in latitude, longitude or elevation by 
this species, as demonstrated by three bivariate
