![]() Here's a link that lists the codes/abbreviations used by bird banders, and what they mean. Bird Banding Laboratory More later on those feathers. I have a nice diagram, somewhere... BTW, the alula are short little funny feathers located at the birds' wrist (kinda like a thumb) and aids in flight manuevering, especially when landing.

Thank you
Now on to what is meant by HY/SY birds???? What I'm gathering from the info is... on a younger bird there is more grey and less blue and bars in the feather markings.
