Is it possible to get juvenile cormorants to subspecies level?
No interactions present.
Current thinking on the identification of carbo and sinensis Cormorants is that the angle made by the gape line and the rear edge of the gular pouch is the most reliable feature for use from photographs (if a photo showing the subject in profile can be taken).
If the angle is under 66 degrees carbo is the likely ID, if it is above 72 degrees then it is sinensis.
(There is overlap between 66-72 degrees).
The angle on the bird in your photo is about 90 degrees - which should make it sinensis.

Thanks Roy - that was the paper I was trying to recall.
The magic of nature is all around us - we just need to learn how to see it.
You can add the sub-species ID as a revision in iSpot if you want.
