This paper describes a new approach for wing shape determination of free flying birds during flapping flight. The optical based measurement method called "image pattern correlation technique" (IPCT) is described as well as modifications of this technique in order to measure wing surfaces formed by feathers. Furthermore a newly developed camera driving system is introduced, which enables a movement of the surface measurement system synchronized with a bird. The application of this system to free flying barn owls is described together with high resolution surface results, obtained during free flapping flight of the bird. © 2012 Springer Berlin Heidelberg.
