Model coefficients (median estimates, [5^th, 95^th percentiles]) in PGLS models (ΔAIC from the best model is less than 4) for determinants of the price of birds in Taiwanese pet shops, were calculated over 100 randomly selected likely phylogenetic trees. Model ranks (top 3 rankings shown) are based on ΔAIC. Parameter Lambda (λ) indicates the strength of phylogenetic signal in the price of birds for sale in Taiwan for each likely model. IUCN status divided species by whether they are classed in the category of least concern.
