Re: TRV 7-28-18 – seedeater taxonomy
White-collared Seedeater was recently split into two species. The West Mexican form that occurs in San Diego as an escapee from the pet trade is now Cinnamon-rumped Seedeater. (As far as I know, all "White-collared Seedeaters" in San Diego refer to this taxon.) The more widespread form that occurs from the Rio Grande Valley in Texas south to Panama is now Morelet's Seedeater.
The eBird taxonomic update will begin in the second or third week in August, but in the meantime, if recording this bird in eBird, use White-collared Seedeater (Cinnamon-rumped).
