Table 2. Best-fitting models of resighted banded ibis assessed using the robust design within Program MARK.
Model* | AICc | ΔAICc | Model Likelihood | Num. Par | Deviance |
{φ(g,.), γ′′(g,.), γ′(g,.), p(g,t) = c(g,t)} | 2348 | 0 | 0.9943 | 98 | 2871 |
{φ(g,t), γ′′g,.), γ′(g,.), p(g,.), c(g,.)} | 2359 | 11 | 0.0050 | 67 | 2863 |
{φ(g,t), γ′′(g,t), γ′(g,.), p(g,.), c(g,.)} | 2363 | 15 | 0.0007 | 133 | 2783 |
The robust design estimates five parameters in each model: survival rate (φ), emigration rate (γ” ), immigration rate (γ’ ), initial capture probability (p) and recapture probability (c). The symbols within parentheses indicate whether the parameter is held constant ‘.’ or whether separate parameters are include for each sex (g) or survey interval (t).
Surveys were conducted quarterly (n = 16) over 4-years.
