Research aimed to establish the anatomy of female and male at Great Alexander parakeets. Determinations were carried out on a total number of 10 individuals: respectively 5 females and 5 males. The main aimed parameters were represented by: ovary position, ovary weight, oviduct weight and oviduct length, testicles weight, dimensions of deferent tract, respectively the weight of deferent tract. At the Great Alexander studied females, ovary was situated in the abdominal cavity, under the ventral side of left kidney. Average ovaries weight reached 3.0458 ± 0.0616 g, with minimal value of 2.873 g and a maximal one of 3.215 g. Oviduct weight reached an average of 1.0936 ± 0.0705 g with a minimal value of 0.937 g and a maximal one of 1.294 g. Regarding the oviduct length, the mean established value, for the studied birds, was 74.6166 ± 1.4802 mm, with limits between 69.526 mm and 78.231 mm. Exploring the male reproductive system of budgerigars, the testicles were found in the abdominal cavity, at the level of the last 3 ribs. In all situations, the weight of the right testicle was higher than the left one. So, the average weight of the left testicle reached 2.5481 ± 0.1276 g, with a minimal of 2.2267 g and a maximal of 2.9758 g. Speaking of the deferent tract size, its medium length reached 72.6924 ± 0.4262 mm while trait variability was very low (V%=1.8541). Weighting of both deferent tracts oscillated between 0.2125 g for the right one and of 0.3016 g for the left one, with an average of 0.2640 ± 0.0086 g.

Key words: ovary weight, oviduct weight, oviduct length, testicles weight, dimensions of deferent tract, weight of deferent tract
