Odd as it may seem, birds sense the change in daylight directly through their skulls. Research on blinded birds in the past proved this point. Check out Birder's Handbook, or any ornithology text. That then triggers gonadal changes, and the onset of breeding behavior. It seems reasonable that it would also trigger pre-alternate molt, but I'd have to check that fact.
