Thank you for posting this record.
This bird was ringed on 12 February 2019 while it was still a chick in a nest at Mai Po. It's great to know that it is still doing well.
There are also other sightings of the same bird here:

If possible, could you post the whole picture (or send to me privately). Can you also confirm the date of your sighting - your post states 21st December, which is a date in the future! I'd also be interested to know exactly where on the reserve you saw the bird, so that we can understand more about how Collared Crows move around the area.
Thanks again!
