AB  - The aim of this study was to estimate and compare volume fraction values of grey matter (substantia grisea) in thecervical enlargement (intumescentia cervicalis) using stereological methods for two different types of birds. Ten pairs of quails andchickens were included in this study as one of them is flying and the other one is flightless bird species. The tissues cut into serialsections of 5 µm thickness were selected according to systematic random sampling and stained with cresyl violet. Volume and volumefractions were calculated in accordance with the Cavalieri principle. Student’s t-test was used to evaluate volume fraction differencesamong the species. The volume fractions of grey matter in cervical enlargement of chicken and quail were 0.277 ± 0.005 and 0.346 ±0.014 (Mean ± Standart Deviation), respectively (p < 0.001). There was a significant difference between chicken and quail cervicalenlargements in terms of volume fraction values of grey matter. On the other hand, the Cavalieri principle was considered as anunbiased, accurate and effective method for volume and volume fraction estimations.
