[Gulls] Relicit Gull 遺鷗

Looks good to me.  Congratulation.  Would you and other photographers submit your best photos on it to the new HKBWS photoguide?  Thank you.

Dear CK,

Yes, thanks for reminding me to check the books (and photo galleries).  Indeed sub-adult Heuglin's Gull types can not be ruled out very well.  The key features are the wing pattern, bill shape, and the tail pattern.  I think the wing pattern fit both, the bill shape fit Relict better, but the tail seems to fit Heuglin types better.  I believe overall this bird fits Relict Gull better, but would welcome other suggestions and discussions.

Thanks Paul for comment. That is why I like open discussion. You got different opinions and methods so that knowledge in birds can be built up.
