Archived 2011-2012 topics: Large-billed Seed-finch (Oryzoborus crassirostris): request for information
Large-billed Seed-finch Oryzoborus crassirostris is listed as Least Concern on the basis that it does not approach the thresholds for Vulnerable under any of the IUCN criteria. Recently, it was suggested that this species is still subjected to high trapping pressure for the internal cagebird trade in the Guianas at least (R. Clay in litt. 2010), whilst in Brazil it is described as very uncommon (A. C. De Luca in litt. 2010). Up-to-date information is requested on this species, in particular the estimated rate of decline over 11 years (estimate of three generations) and the severity of trapping pressure and other potential threats.
