A molecular sexing method using the intron-size difference between chromo-helicase-DNA binding protein (CHD1) genes on the Z and W sex chromosomes (CHD1Z and CHD1W, respectively) was developed for wild Jungle crows and wild Carrion crows. The polymerase chain reaction product sizes were 661 bp for CHD1Z and 465 bp for CHD1W in both the Jungle and the Carrion crows. Each male crow sample produced a single fragment (CHD1Z), whereas female samples produced two fragments (CHD1Z and CHD1W), which differed by 200 bp in crows. In the present study, sexing live Jungle and Carrion crows was performed by applying the method to a feather for molecular sexing.
