The Tilery became over time a haven of peace for bats. Their conservation was an integral part of the rehabilitation of the site with the implication of the conservatives of the Natural history museum of Bourges, also responsible for the association " Chauve-qui-peut ". The objective was to lead to the outcome of the works while allowing the bats to keep living in a part of the site. Thus measures of support were implemented.
The symbolic species of The Tilery is unquestionably the grand murin, the most gregarious species of the department of the Dear. In La Guerche-sur-l'Aubois, females, accompanied by their unique kid, oscillate between the school and the Tilery from June. Chiroptera found a quality summer refuge, face to the canal and of meadows from the Valley of Aubois, ideal for their first parts of hunting there.
Other species are also present on the site: Barbastelle of Europe, common Sérotine, grey Oreillard, Pipistrelles etc. In July 2017, 876 individuals were counted on the site.
