LC
Large Tree-finch Camarhynchus psittacula

Justification
Although this species may have a small range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Distribution and population
This species is endemic to the Galápagos islands, Ecuador, with breeding populations on Isabela, Santa Cruz, Santa Fé, Fernandina, Santiago, Floreana, Marchena, Pinta and Rábida (Castro and Phillips 1996, Stotz et al. 1996). It is extinct on Pinzón (Castro and Phillips 1996).

Population justification
The global population size has not been quantified, but this species is described as 'uncommon' in at least parts of its range (Stotz et al. 1996).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Ecology
This species inhabits lowland deciduous and montane evergreen forest, between 300 and 700 m altitude (Stotz et al. 1996). It feeds on the fruits of native plant species, and on insects for which it forages under leaves and excavates dead branches (Castro and Phillips 1996).
