Effects of human activity on populations
Human activity probably has little direct effect on Lesser Violetear, other than the local effects of habitat destruction. Since Lesser Violetear prefers open, shrubby habitats, rather than closed-canopy forest, however, it may even benefit from intermediate levels of habitat disturbance.
