From: Niche partitioning among three tree-climbing bird species in subtropical mountain forest sites with different human disturbance

  1. Niche breadth values and 95% confidence intervals for brown creepers (Certhia americana), pygmy (Sitta pygmaea), and white-breasted nuthatches (S. carolinensis) based on sightings and foraging use of trees in (a) disturbed and (b) undisturbed forest sites.
