Whistle down the wind. If those who know better think the phrase connects, you might like this citation and explanation for your collection - Othello III.iii.262 "... If I do prove her haggard, / I'd whistle her off and let her down the wind, / To prey at fortune....".
Note in The Yale Shakespeare, Rev'd Tucker Brooke (copyright 1918, 1947): "...'The falconer always let the hawk fly [whistle her off = start her] against the wind; if she flies with the wind behind her, she seldom returns. If therefore a hawk was for any reason to be dismissed, she was "let down the wind," and from that time shifted for herself and "preyed at fortune" ' (Johnson)".
