[Eagles] Eastern/Western[?] Marsh Harriers in Fight (澤鷂/白頭鷂[?])

Nice pictures. Do you have more pictures of the right hand bird. Especially showing the underwing pattern and the rump pattern? Thanks

I think the under-wing is spot on for WMH and that the breast, forewing, and rump markings are all within the range of WMH.  The biggest problem in my mind in the head pattern.  The dark eyestripe is just too poorly defined and does not reach the base of the bill as it should on a juvenile WMH.  I also think that the crown is too streaked. Below is a link to a useful online article discussing EMH and WMH hybrids.
