The essentials for a bat walk are a good bat foraging habitat (such as a park, woodland or lake) that is accessible for people to walk around at night, and some bat detectors to hand around that enable the bats’ ultrasonic calls to be heard.
Normally bat walks are preceded by a talk on bats in general and the species that are likely to be seen or heard at the site. This may take place outdoors at the start point of the walk, or can involve an illustrated talk inside a nearby venue. How much other wildlife gets pointed out depends on the wider knowledge of the bat walk leaders, but few people can resist stopping to listen to the calls of owls or watch foxes, badgers and even toads that are spotted roaming around at night.
