The following are cryptic clues to birds. I haven't been given numbers of letters in answers I'm afraid:
1) Flier 2) Vegetable stuck in a weather vane 3) Flown over the Atlantic for Christmas 4) Half a town in Yorkshire 5) A drinking smile 6) Jonathon pots and comments
I'd actually considered both Turkey and Swift. However, I have Turkey for another answer (I believe Canadian Goose may be better) and I don't see how Swifts 'pots and comments.'
