A comparative study has been made of the seasonal fluctuations in the testicular asymmetry of the house crow, the common mina, the bank mina, the house sparrow and the roseringed parakeet. Their left testis usually attains a larger size and higher weight than the right one. These differences are more pronounced during the breeding seasons.
对家鸦、家八哥、林八哥、家麻雀和玫瑰环鹦鹉睾丸不对称性的季节性波动进行了比较研究。它们的左侧睾丸通常比右侧更大、更重。这些差异在繁殖季节更为明显。
