Hi, Pavane - the two winged birdie ^^ means that one of the harvesters has "harvested" a song - copied it for inclusion in the Digital Tradition Folk Song Database (click) our collection of some 9,000 folk songs. If a song has the dreaded three-winged birdie with the redundant third wing ^^^, that means the song is already in the Digital Tradition or has already been posted at Mudcat, and the redundancy has been noted.
