Check-list Supplement Redux: v. 2013 family changed. Those on the ABA Checklist are now in the following order: • Blue Mockingbird • Gray Catbird • Curve-billed Thrasher • Brown Thrasher • Long-billed Thrasher • Bendire's Thrasher • California Thrasher • Le Conte's Thrasher • Crissal Thrasher • Sage Thrasher • Bahama Mockingbird • Northern Mockingbird –––––––––––––––––––––––––––––––– The sequence of the three Haemorhous (formerly Carpodacus) fnches has changed to the following: • House Finch • Purple Finch • Cassin's Finch –––––––––––––––––––––––––––––––– The subfamily Drepanidinae (Hawaiian honeycreepers) was subsumed into the subfamily Carduelinae. The Hawaiian "honeycreepers" really just are, it seems, highly diverged members of the goldfnch clan. Their position in the list has changed, now coming immediately after Eurasian Bullfnch, but their internal sequence is unchanged. –––––––––––––––––––––––––––––––– Hawai'i Creeper, one of those aforementioned "honeycreepers", underwent a change of scientifc name. It was formerly a member of the monotypic genus Oreomystis. It is now Loxops mana. It shares this genus with 'Akeke'e and 'Akepa, and it now precedes the former in the checklist sequence. • Split of American Thalasseus acuflavidus (Cabot's Tern) from Sandwich Tern (T. sandvicensis). • Split of Guatemalan Pygmy-Owl (Glaucidium cobanense) from Northern Pygmy-Owl. • Split of Velasquez's Woodpecker (Melanerpes santacruzi) from Goldenfronted Woodpecker. • Split of Chiapan Myiarchus flavidior (Ridgway's Flycatcher) from Nutting's Flycatcher. • Further splitting of Canada Goose. • Split of White-breasted Nuthatch into two to four species. • Lump of the three American-breeding rosy-fnches into American RosyFinch (L. tephrocotis). Notable Proposals That Were Not Accepted On the Horizon • A change in genus name for Yellowcrowned Night-Heron from Nyctanassa to Nyctherodius. The AOU CLC is anticipating voting on a retooled proposal to split Whitebreasted Nuthatch, but perhaps not in Gray Silky-flycatchers, now Ptiliogo- nys cinereus, in Oaxaca, Mexico. Photo © Michael L.
