27 October 2015 | Birder's Guide to Listing & Taxonomy Pseudonestor Hemignathus Akialoa † Magumma Chlorodrepanis Viridonia † Loxops Bahama Woodstar Split –––––––––––––––––––––––––––––––––– • Bahama Woodstar (Calliphlox evelenae) • Inagua Woodstar* (Calliphlox lyrura) This split was adopted on the basis of dif- ferences in sounds (vocal and mechani- cal), genetics, and morphology: Inagua has narrower, outwardly-fared outer rectrices and a magenta (vs. greenish) crown. For more information, includ- ing photos comparing the two species, visit ABA Area records of birds from this complex are thought to pertain to Bahama Woostar (sensu stricto). A proposal to name the two species "Bahama Sheartail" and "Inagua Sheartail" was not accepted for now, because the committee wants to wait until the entire hummingbird family undergoes a major overhaul of scientifc and common names, based on a 2014 phylogeny that challenged much of the status quo, including ABA Area species like Anna's and Costa's, which seem to be nested within Selasphorus. New Genera and Sequence for White-tailed Hawk and Roadside Hawk –––––––––––––––––––––––––––––––––– White-tailed Hawk changes from Buteo albicaudatus to Geranoaetus albicau- datus. Genetic data show that it is not a Buteo, but rather, is more closely re- lated to Black-chested Buzzard-Eagle* and Variable Hawk. Speaking of which, Red-backed Hawk (Buteo polyosoma)—of which there is an unaccepted Colorado record—has changed to Variable Hawk (Geranoaetus polyosoma). Roadside Hawk changes from Buteo magnirostris to Rupornis magnirostris. New Buteonine Hawk –––––––––––––––––––––––––––––––––– The new sequence is as follows: Roadside Hawk Harris's Hawk White-tailed Hawk Gray Hawk Red-shouldered Hawk Broad-winged Hawk Hawaiian Hawk* Short-tailed Hawk Swainson's Hawk Zone-tailed Hawk Red-tailed Hawk Rough-legged Hawk Ferruginous Hawk Falcon Subfamily Reshuffe –––––––––––––––––––––––––––––––––– The caracara subfamily was absorbed into the "regular falcon" subfamily, Falconinae. Laughing Falcon* moved from that sub- family into the forest-falcon subfamily, which had to be renamed because of pri- ority. The subfamily containing forest- falcons and Laughing Falcon is now called Herpetotherinae. Western Spindalis a Tanager No Longer –––––––––––––––––––––––––––––––––– The genus Spindalis has joined that great taxonomic purgatory known as "incertae sedis". The spindalises appear immediate- ly after the true tanagers in the sequence. "New" Tanagers and a Reshuffe –––––––––––––––––––––––––––––––––– As long expected, seedeaters, grassquits, and Bananaquit have been added to the tanager family. The new sequence of gen- era is as follows, and the following are the only species of true tanager now found in the U.S. and Canada. Paroaria (including Red-crested* and Red-capped* cardinals) Coereba (Bananaquit) Tiaris (including Yellow-faced and Black-faced grassquits) Sporophila (including White-collared Seedeater) White-tailed Hawk has been moved to the genus Geranoaetus .
