In the article, the texts of Kazakh songs with ornithonyms are grouped in accordance with their use. The use of ornithonyms in the lyrics and their semantic meaning are also divided into thematic groups. The thematic group is based not only on the paradigmatic connections of ornithological names, but also on denotative ones. The linguo-cognitive semantics of the thematic group of ornithonyms and lyrics is determined. The semantics of ornithonyms in the lyrics is based not only on the similarity of the lexical meaning of words, also on the allegorical metaphorical meaning of objects and phenomena by which they are called. The semantics of ornithonyms in the lyrics reflects the cognitive characteristics of the ethnos in the perception of the world through a song. The presence of birds in the lyrics, close to the worldview of the ethnic group, is an indicator of national culture, which to a certain extent determines the ethnic identity of the ethnic group. In the spiritual world of an ethnos, ornithonyms in Kazakh poetry have long existed and are a spiritual value that remains to this day. The linguo-cognitive analysis of the language units of the lyrics reveals its significance in the Kazakh ethnic group.
