Sažetak
For most bird species, vision is the most important sense. Some species, such as songbirds, can see a part of the ultraviolet (UV) light range. In addition to the pigmentary and structural colours of feathers, some species have also developed UV coloration, visible to birds that see UV wavelengths. The research was performed on the skins of 45 bird species from the scientific collection of the Institute of Ornithology CASA, on three individuals per species. The aim of the study was to determine which species of birds of the Croatian fauna have UV coloration and to investigate UV colours can help in identification of certain species. We studied differences in UV coloration between 1) predominantly monochromatic and multi-coloured birds ; 2) birds that have only pigmented coloration and those that have also structural coloration ; and 3) songbirds and other species. The results showed that UV reflection occurs more frequently in monochromatic birds, in species that also have structural coloration, and in songbirds. To determine the systematic affiliation of studied species, the research should be repeated on a larger sample. The lack of skins of females of many species impeded testing the differences in UV coloration between sexes and determination of the sexual dimorphism in particular species. Student research using scientific collections develops an interest in scientific work, especially when combining knowledge in different fields as biology, chemistry and physics.
