Which is NOT a characteristic of bats' roosting locations?

Bats exhibit a diverse range of roosting behaviors and preferences, making them adaptable to various environments. A key characteristic of their roosting locations is that they tend to favor areas that provide protection and shelter from environmental elements and predators. This includes locations like indoors, semi-enclosed structures, and partially sheltered areas, which all offer the necessary safety and temperature regulation that bats require.

In contrast, open areas typically do not provide the same level of protection. While some bat species may be observed in open environments during foraging or hunting for insects, these are not suitable roosting sites. Roosting requires a secure place that can offer cover from the elements and threats, making exclusively open areas an unsuitable choice for bats to rest and raise their young. This is why excluding open areas from the list is accurate; they do not align with the common roosting characteristics of bats.
