    • UV reflectance as a cue in egg discrimination in two Prinia species exploited differently by brood parasites in Taiwan 

      Yang, Canchao; Wang, Longwu; Hsu, Yu-Cheng; Antonov, Anton Tinchov; Moksnes, Arne; Røskaft, Eivin; Liang, Wei; Stokke, Bård Gunnar (Journal article, 2013)
      Birds are capable of seeing the ultraviolet light (UV) spectrum and as a consequence have evolved UV-reflective structures with signalling functions. Avian eggs also reflect in the UV spectrum but the importance of UV egg ...
