Based on the published findings (Koštejnová 2013, Slezáková 2014, Gajdošík 2020), unpublished data from museum specimens (2005 – 2013), and data from field surveys (2005 – 2023), a total of 13 bat species were recorded in the urban area of Ostrava in North Moravia. Common species in the area included , , , and . was eudominant species (D = 74.41), followed by (D = 11.41). was a subdominant species (D = 4.59), followed by (D = 3.77) and (D = 2.45). The occurrence of was recendent (D = 1.33), and the occurrence of (D = 0.51), (D = 0.51), (D = 0.31), (D = 0.31), (D = 0.20), (D = 0.10), (D = 0.10) and (D = 0.10) were subrecendent. In the summer season, eudominant species were (D = 76.84), followed by the (D = 10.63), subdominant (D = 4.74), and (D = 3.89), with being recendent (D = 1.37). In the winter season, eudominant species were (D = 62.50), followed by the (D = 34.38) and subdominant (D = 3.13). However, the species composition inside and outside buildings differed significantly. In the summer season, eudominant species inside buildings was (D = 99.57), followed by the subrecendent species (D = 0.29) and (D = 0.14). Outside buildings, (D = 40.16) were eudominant, followed by (D = 17.72), (D = 14.17), and (D = 14.17), with (D = 5.12) was dominant, and (D = 1.97), (D = 1.97), (D = 1.18), and (D = 1.18) were recendent species. In the winter season, eudominant species inside buildings were (D = 68.75), followed by (D = 25.00), and the situation was very similar outside the buildings during this period, with eudominant (D = 56.25) and (D = 43.75). Two roosts of the maternity colonies were recorded in city buildings: in Výškovice, Lumírova 10, in a expansion joint near the balcony on the top floor of a panel residential building; and in Zábřeh, Plzeňská 2617/4 and Plzeňská 2617/6, in expansion joints on the top floors of an old panel building used as a hostel and apartment building.
