2/5 #WBTC1 #EvoBeh1 We found out that R. nitidula is very common, https://abs.twimg.com/emoji/v2/... draggable="false" alt="♂️" title="Male sign" aria-label="Emoji: Male sign"> sing exposed to bat predation and don’t stophttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🎶" title="Multiple musical notes" aria-label="Emoji: Multiple musical notes"> when https://abs.twimg.com/emoji/v2/... draggable="false" alt="🦇" title="Bat" aria-label="Emoji: Bat"> around.

We used custom made affordable https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤑" title="Money-mouth face" aria-label="Emoji: Money-mouth face"> 3D setup to record bat predation success and recreate flight velocity and the direction of the attack.

4/5 #WBTC1 #EvoBeh1 Our preliminary results (2 out of 8 https://abs.twimg.com/emoji/v2/... draggable="false" alt="🦇" title="Bat" aria-label="Emoji: Bat"> analyzed) show a significant reduction of the bats’ predation success in the presence of R. nitidula song (X2 =7.6421, df =1, p < 0.006) compared to the silence control.
