Take a pair of scissors and carefully cut out the silhouette. This is indicated in the lower left corner of the page.
#BAT SILHOUETTE PDF#
Download the pdf with the silhouette (in Dutch or in English) and print the only you like at the correct format. Then the image was scaled so that the wingspan matches the average wingspan mentioned in Limpens et al (1997).įinally, it is time for some craft work. Once vectorised, the left side was mirrored in order to get a complete bat with fully extended wings. Since the drawings were quite detailed, I decided to not only digitise the outline but also the main anatomical features like the contours of the body, ears, mouth, arms, fingers, legs and tail. I ended up scanning and vectorising the left side of the bat. Peter was kind enough to give his permission to use his drawings as a template for the silhouettes and share the result. The drawings, made by Peter Twisk, display a bat seen from the ventral side with the left wing full extended and the right wing folded. I recalled that Limpens et al (1997) has nice drawings of several bat species. a long eared bat should have long ears, a noctule should have narrow wings while a serotine should have broad wings. Some asked for the template or suggested to use a more anatomically correct template. She took a simple template and re-sized it to match the wingspan of the different species.
This is useful to illustrate the true size of bats to the public. Hillie Waning Vos posted a message in the Facebook group “vleermuizen” showing how she created some bat silhouettes at 1:1 scale.
