1)<p>Note that since the individual responds only to the nearest recognized tree (of type depending on the discrimination level, see ‘Methods’), the effective ‘infinity’ is achieved by setting a perceptual range larger than the largest nearest neighbour distance between the recognized trees.</p

Proportion of successful bats in search for roosts, in relation to perceptual range, group size, tree discrimination skills and forest type.

Mean search time (±SD) of tree cavities by bats in relation to forest type, bats’ perceptual range and skills of tree discrimination.

<p>Proportion of trees in forests are coded as A/B/C, A: unsuitable, without cavities, B: confounding, apparently suitable but without cavities, C: suitable, with cavities. For a description of the tree discrimination levels, see Methods section.</p
