upland buzzard(Buteo hemilasius) vs common buzzard(Buteo japonicus)? (1 Viewer)

[firepig36]

hi. I always have trouble distinguishing upland buzzard and common buzzard. How can I distinguish them?
I know that I can distinguish them if I see their upper side of the wing(by the width of white mark), but I have no idea what should I do if I see them flying away from below.
im not sure if my question is adequate for this forum. so if it isnt, please excuse me. im a korean and noob to this site so everything im doing may seem weird to you guys.
thx

Not much wrong with your post i reckon. Although usually specific cases are posted and debated here.
The subject of difficult Buteo in Korea has been treated here fairly recently.

Hello, Is this an upland buzzard? I'm not 100% sure. Thanks, Rob

As you have noticed the more expert Buteoists here have not replied. That may be due to the fact that you are posing a very broad question.
There are some ID papers easily found online that describe at least a few of the features.
Maybe it is best to leave this one be, and start another thread as soon as you have been able to find/photograph a bird that begs the question: Upland or Eastern Buzzard... or Rough-legged Buzzard, or stray Long-legged Buzzard.

Good luck with this
cheers

ps. I have been struggling with the duo since yesterday as 2 Japanese buteo records landed on my plate, both most likely wrongly identified.

How kind you are.
As I keep watching birds in the filed, I become to have the ability to identify two birds with a kind of "feeling".
I cannot explain exactly what differnt point of them makes that feeling, but there is definitely something 🤣
Thank you and have a good time with bird
