Table 1.

Set of candidate models for modeling the environmental niche of Yellow-headed Brush-finch and Tolima Dove in the Colombian Andes. Listed are the four top-ranked models for each species. A total of 15 and 11 different models were fitted for Yellow-headed Brush-finch and Tolima Dove, respectively. Models contain different combinations of coefficient features (L: linear; L + Q: linear + quadratic; H + Q: hinge + quadratic) and regularization constants (0.2, 0.5, 0.8). Models were ranked based on the difference from the top model in AIC_c scores (ΔAIC_c). k is the number of model parameters, –2lnL is the maximized log-likelihood, and w_i is the Akaike weight
