This is the larger of the two races of Grey Drongo inhabiting 

 Siam ; we have listed it with some hesitation as D. I. hojiwoodi 

 Baker, as we think that the author, rather than having remedied 

 the confusion which existed in this group of birds, has increased it. 



All the examples we have seen were taken in the winter and, 

 like D. m. cathoecus, it possibly comes south for that season.
