Four types of Chaffinch rain-calls were found in Ukraine: “rülsch” - a trill signal widely spread in Europe; “hui” - a whistle signal that occurs in North-Western and Central Europe; “Crimean” whistle signal known only from Crimean peninsula and “Caucasian” signal occurring in Caucasus, Asia Minor and Balkans. Sonograms of rendition versions are given for all of the call types. Distribution of dialects of Chaffinch rain-calls in Ukraine was examined. “Rülsch”- dialect occurs at most of the plane Ukraine and Carpathians. Owing to colonizing artificial afforestations in steppe zone this dialect population’s range expanded southward to the coast of the Black and Azov seas. “Hui”-dialect is spread in the Lower Danube region. At the North-Eastern Danube delta Chaffinch’s with “hui”- and “rülsch”- rain-calls are found together and a bird was found that uttered both signals alternately but hybrid signals were not registered. It may attest to recent invasion by “rülsch”- population of Chaffinch’s there. “Crimean” dialect is distributed in mountainous Crimea and in most of the Crimean steppe zone. “Caucasian” rain-call renditions are registered in cases of individual vagrant birds in eastern Crimea and Lower Danube region
