Molecular sex identification of Malaysian White‐Nest Swiftlet ( Aerodramus fuciphagus Thunberg, 1812)
Abstract The difficulty in differentiating the sex of monomorphic bird species has made molecular sexing an important tool in addressing this problem. This method uses noninvasively collected materials such as feathers and may be advantageous for sexing endangered as well as commercialized bird spec...

Results from sequencing showed no variations in the base sequences of the CHD‐W and CHD‐Z amplified fragments within the same sexes, except for one male sample (A23) where at position 166, a base substitution occurred (G → A). Phylogenetic analysis of CHD‐W showed that four (Apodiformes; Gruiformes; Passeriformes; and Pelecaniformes) out of the five orders investigated had formed four clear clusters within their orders, including the studied order: Apodiformes. Whereas in CHD‐Z , four (Accipitriformes; Columbiformes; Galliformes; and Passeriformes) out of five orders investigated formed four clear clusters within their orders, excluding the studied order. In addition, A. fuciphagus and Apus apus (both Apodiformes) showed less divergence in CHD‐W than CHD‐Z (0% c.f . 9%). The result suggests that in A. fuciphagus , CHD gene evolution occurred at a higher rate in males ( CHD‐Z ) compared to females ( CHD‐W ). This finding may be useful for further studies on sex ratio and breeding management of A. fuciphagus .
