If you compare photos of the 2012 and 2014 Greylag Goose, they look quite different
Here the July 2012 bird



Here the August 2014 bird



Whether these differences over two years are significant or not, I'm not expert to tell.

The Ferruginous Duck can't be compared - the July 2012 bird was a first summer, the current bird is an adult.

Thanks to the photographers for these images. They have all previously been posted on the website.

There is no definitive answer to this question, except to say

'showed no signs of being ex-captive, although the possibility cannot be excluded' (2012 HK Bird Report page 35)

The July 2012 Ferruginous Duck was accepted as wild and is included in the officially accepted records.

The position with the July 2012 Greylag Goose needs to be reviewed by the Records Committee, together with the August 2014 record. So for the moment, it will not be included.
