Nice one, Mikey! Took awhile to get it to congeal (the meta, not the gravy)... rabbit holes galore: thrown by
37D Some are early ... BIRDS?? or
12D Balkan citizen ... Part of Turkey is part of the Balkans; or
30A: there
is a Great Wall of Turkey; or notions of Turkey Spam (
58D) or Turkey Bacon (
36A)... or dare I say
15A "Wow, that describes me exactly" ... turkey??? I daren't
. But once it gelled (like cranberries) it was an elegant solve. Enjoyed it!!
