The site has been upgraded to use Version 4 of Birdlife's Working List. The only significant changes are that Variegated Fairy-wren and Graceful Honeyeater have been split, into Variegated Fairy-wren and Purple-backed Fairy-wren, and Graceful Honeyeater and Cryptic Honeyeater, respectively.  The other changes are the addition of 13 vagrants.  The changes are detailed on the Resources - Taxonomic Changes page.
