Red Kite tagging

Hotei

I'm just wondering if anyone here is familiar with the colour coding on Red Kite tags? I was delighted to see a Red Kite here in west Kildare on Thursday (only the eight sighting officially recorded since 2013), and although I only got distant shots of the bird, I was later able to zoom in on the images I took which showed the coloured tags on the bird; the left tag was yellow with a green bar, and the right tag was green but with no coloured bar visible (unfortunately I couldn't read the numbers). Having searched online, I found very little information on the colour coding used in the reintroduction project. I'm led to believe that a blue tag with a yellow bar on the left wing tells us the bird was Irish bred, while the right tag tells us what year the bird was born.
The tags on the Red Kite I saw matches colour coding used on birds bred in the Chilterns in England - is it possible this bird was bred there and introduced here as part of the project? It would be unusual would it not to have a very similar colour coding system here which is similar to that of another project in the British Isles? Could the bird have migrated here itself? By the way, I contacted The Golden Eagle Trust on Thursday, but haven't had a reply yet.

The Red Kite was being mobbed by a Hooded Crow which was sending it away from me, so the images I took are distant ones unfortunately:

Not too sure about the colour or numbering of the tags in the past 3 years . But the birds we tagged in the fingal area when introduced were all white tags with a letter,number or symbol with blue bar at the end of the tags. I haven't had much to do with the project in recent years due to personal issues. That said im delighted the birds have bred in the general area.

I spent time living near a release sight in the UK. The birds bred very successfully & are now a common site. The funny thing is it was next to the motorway that's used by coach loads of twitchers on the way to see the Red Kites in Wales.
