Front cover photo by Héctor Gómez de Silva of Mexico City, Mexico: Grayson’s Streak-backed Oriole (Icterus pustulatus graysoni), Tres Marías Islands, Nayarit, Mexico. The Tres Marías Islands are home to about 24 endemic taxa of birds, some very distinctive, such as Icterus pustulatus graysoni, in which the streaks on the back are nearly lacking. But the islands’ avifauna as a whole is still incompletely known. In this issue, Héctor Gómez de Silva, Mónica G. Pérez V., Javier Cruz N., Juan Cruzado C., Robert A. Hamilton, Santiago Vásquez V., and Miguel Angel Cruz N. advance our knowledge of it greatly.
