Juvenile pallid or montagu's harrier - Portugal (1 Viewer)

[ASBotelho]

I would really appreciate some help with this ID! Thank you in advance!

The harrier was high and always gliding so the photos are quite poor and the position does not help.
Is it possible to tell if it's a monty or a pallid? (or hybrid)
It does seem to have a pale trailing edge to the inner primaries, overall dark secondaries (altough the photo doesn't allow much analysis). Can't say much about the head pattern...

Seen on the 8th of October in Sagres, Portugal.
P.S. There was a Pallid in the area, seen a week or a few days before (couldn't get hold of the photos).

Rufousy underbody and coverts + no dark shoulder/chest-side = Montagu's harrier. Apparently.

Thank you for the reply!
About the colour/tone of the underbody and wing coverts, in the field it actually looked pale orange, some of the comments I heard of other birdwatchers was "It's macrourus, it's so pale". I had to push the contrast of the original photos because they are overexposed, I'll attach them bellow.
