Plausible causes of seed preferences and diet composition in seed‐eating passerines

Plausible causes of seed preferences and diet composition in seed‐eating passerines

We evaluated whether seed mass, handling time, handling efficiency and profitability account for (a) preferences in controlled experiments and (b) field‐diet composition of four bird species of the Monte desert, Argentina. The question of whether birds maximise their energy intake rates while feedin...
