Incorrect symbols

All forest birds are functionally extinct on the island of Guam, whereas relatively healthy bird populations remain on three nearby islands of Saipan, Tinian and Rota.

The symbols representing "birds" or "no birds" are reversed in this figure. The symbol for Guam should be a bird with a line through it, whereas the symbols for Rota, Tinian and Saipan should be a bird without a line through it.
