Asymptotic richness for avian groups categorized by habitat specialization or threat across arabica and robusta stands.
| Category | Observed | Chao | First-order jackknife | |||
|---|---|---|---|---|---|---|
| Arabica | Robusta | Arabica | Robusta | Arabica | Robusta | |
| Forest-dependent | 74 | 66 | 88 (10.3) | 66.3 (0.8) | 86.9 (3.9) | 68 (1.4) |
| Endemic | 14 | 11 | 20.2 (7.5) | 11 (0) | 19 (2.2) | 11 (0) |
| IUCN Red-Listed | 3 | 3 | 3 (0) | 3 (0) | 3 (0) | 3 (0) |
| Frugivore | 22 | 22 | 28.2 (7.5) | 22.7 (1.3) | 27 (2.2) | 24 (1.4) |
| Insectivore | 51 | 48 | 68.9 (23.5) | 50 (3.7) | 57 (2.4) | 50 (1.4) |
| Omnivore | 22 | 20 | 30.9 (10.1) | 22.2 (3.4) | 28 (2.4) | 23 (1.7) |
Observed: Observed richness in each habitat type across all point count stations. Chao (standard error) corresponds to the Chao 2 estimator of asymptotic richness. The first-order jackknife (standard error) is another asymptotic richness estimator.
