Morning Bird Calls [updated]

It's 6 a.m. Since about 5 this bird has been serenading me:



I wish I knew what it was. I think it's a currawong, but I'm not sure.

If you listen very closely after the string of bigger, more obvious notes, there is sometimes (I think twice, here) a very tiny, two-note trill, very high. Just beautiful.

Update: It's a magpie!Thank you to the commenter below!
