Ah! but it's such fun playing this game isn't it? I also particularly liked the "Golden Vanity" discussion.

I often gaze at cuckoos to see if the do indeed "wobble" as they fly (ours are different from American ones of course). They don't, as it turns out, although they don't "warble" either.
Thornbills on the other hand do wobble as they fly.

Oh the thornbill she's a pretty bird
She wobbles as she flies.

Not the same ring to it somehow. Cheers, Joy
