Figure 1: Map of study sites. Central panel shows the distribution of study sites in the Taita-Taveta county, south-eastern Kenya. Note that sites were distributed across low-lying areas only, as synanthropic free-tailed bats do not occur at higher elevations of the county (observable as green cover in the centre, centre-bottom, and right areas of the satellite image). Small panels show the ten, 1x1 km sites with roads (black lines) and building footprints (yellow). Building footprints were obtained from Microsoft (2022), and are based on satellite imagery collected in 2020 and 2021. Human land-use in this county spans a gradient of development, from rural areas with predominantly traditional building practices, to more urbanised areas in the townships of Mwatate, Maktau and Voi (labelled), with predominantly modern building practices.
