The first case concerns a male singing strophes containing syllables of Yellowhammer and Ortolan Bunting, both most probably copied in central Europe. These songs often had broken syntax. The second case concerns a male that sang both typical strophes and strophes that had the initial part copied from a local dialect of Redwing, but with a typical syntax for the species. That male mated successfully. Causes and consequences of vocal mimicry in the species are discussed.</span></span></span></p>}, journal={Ornis Norvegica}, author={Osiejuk, Tomasz S. and Ratyńska, Katarzyna and Dale, Svein and Steifetten, Øyvind and Cygan, Jakub P.}, year={2004}, month={Jan.}, pages={73–79} }
