The paper presents the influence of quail eggshell morphology and pigmentation on the visualization of latent fingerprints.Electron microscopy showed that quail eggshells have a smooth surface, allowing for good fingerprint deposition.Techniques used for identification of latent fingerprints were black magnetic powder, cyanoacrylate fuming method, and ninhydrin method.Among these, the best visualization was obtained with black magnetic powder.This technique allows fast, cheap and good quality visualization of fingerprints and easy donor identification.The cyanoacrylate fuming method proved to be the least effective method, and as such is not recommended for use on quail eggs.The pink prints obtained by the ninhydrin method were poorly noticeable on the pigmented surface of quail eggs, though the good print quality allowed for unambiguous donor identification.
