Fork-tailed Woodnymph

A text, in english, from Birdlife International:

Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 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% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but this species is described as 'common' (Stotz et al. (1996).

Trend justification
This species is suspected to lose 15.9-17.6% of suitable habitat within its distribution over three generations (12 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.
