| Popis: | Optimal foraging theory predicts that a hunter should hunt the energetically most profitable prey, often the larger size classes. The eagle owl is a formidable hunter of water voles. Measurements of mandibles of voles eaten by eagle owls indicated a size frequency distribution more skewed toward larger individuals than could be expected, suggesting a selection of voles by the owls. |
