ENOn the basis of the materials in the European Linguistic Atlas the geographical spread of seven bird names along with two names denoting anatomical parts of birds is studied in the dialects of the Latvian and Lithuanian languages (cīrulis 'lark', irbe 'partridge', stārķis 'stork',pīle 'duck', pīļtēviņš 'drake', zuoss 'goose', baluodis 'pigeon, dove', knābis 'beak', uola 'egg'). A common lexicon was observed in Latvian and Lithuanian as reflected in nine maps. Several bird names encompass the entire Latvian and Lithuanian language territory. For some names a common lexical area is formed for the entire Latvian language together with Samogitian dialects, whereas for other names the common lexical area is formed in the Lithuanian and Latvian borderland. A distinctive feature of the thematic group of the lexicon connected with birds are several borrowings in Lithuanian from Latvian and vice versa. [text from author]
