The play on words here are good. At first I thought, a typo on, haze. In the leading verse I think you have over explained it. Maybe, just allowing it to pitter out, like a needle waiting to be found...
The question about the sun is a good injection of curious imagery; making the reader think about the sun and it's link to a search.
So, with the wind come context. You enter the scene with an admission : the wind being a force affecting your being.
I see the hays full of birds being a metaphor for love. Love spilt out for the wind to blow around searching for love, but not finding what it sought.
This poem is obviously personal to you and it's deep meanings allusive, like the needle in the hays.
