Table 2. Model selection of Hawaiian Stilt (Himantopus mexicanus knudseni) nest survival in wetlands on O‘ahu.
Models were ranked using Akaike’s Information Criterion corrected for small sample sizes (AICc). K is number of model parameters, ΔAIC is the difference in AICc value from the top model, and wi is Akaike model weight.

| Day + Vegetation height | 3 | 649.60 | 3.60 | 0.09 |
| Date + Vegetation height + Proximity to water + Vegetation height*Day + Proximity to water*Day | 6 | 649.90 | 3.88 | 0.07 |
| Day + Day^2 | 3 | 649.90 | 3.91 | 0.07 |
