Possible Clues:

• Evasion
• 'Keeping off 501, perhaps, in a ball (9)'
• An opinion about Daniel’s evasion
• Bird mostly seen around island, twitching and ducking
• If Avoca begins before I take part in 2 down, I may still get out of it like this
• I do a jig at last - that's the way I get out of it
• Dare to put in an opinion, or steering clear?
• That's the way I dodge having 501, perhaps, in a ball
• That's a dodgy thing to do with a ball in the 14 down
• So as to dodge it, after 50 I go in rhythm
