There is undertaken the first endeavour to analyze zoonyms designating birds in Nizami Gandzhavi's "Pentalogy". For explication and analysis of the formers the following literature was used: mediaeval productions, such as "Burhoni Kote" (the XVIII-th century), "Ghiyas-al-Lugot" (the XIX-th century), "Fahri Kavvos" (the XIV-th century); modern dictionaries: " The Discitonary of Rudaki's Poetry" , "Interpretation Dictionary of the Tajik Language", "The Dictionary of Djami's Works", "Persian Dictionary" by Muin, "The Dictionary of the Tajik Language Southern Vernaculars", "Brief Interpretation Dictionary of Tajik Literary Language" by S. Aini, "Brief Glossary of "Shak-name". The conclusion is made that 90% of zoonyms designating birds mentioned in Nizami's "Pentalogy" are used in Modern Tajik. Proceeding from this fact, the author asserts that the language of "Pentalogy" and the Azerbayjanian variant of the Persian-Tajik language of the XII-th century are very close to the Persian-Tajik language of Maverannakhr.
