We repeated this procedure for the mean mass of prey killed for each pack size category and for the most frequently preyed
upon prey item (based on prey species, sex and age) for each pack size category.
Similar trend was observed in the present feeding trial where both nymph and adult stages of aphids were preyed
by spiders (Rana et al., 2012).
The Japanese scops owl selected smaller and younger rodents and the Ural owl preyed
on larger and older individuals.
The Eurasian sparrowhawk primarily preyed
on smaller woodland birds, great tits, house sparrows, tits, finches, buntings, thrushes and starlings.
Similarly, within prey species, larger predators preyed
