News from 28th ABA Checklist Committee Report
. . . a hummingbird with two verified north American records, will be acceptable as being “countable” on your North American ABA area list. The Amethyst-throated hummingbird (Lampornis amethystinus) normally resides in Mexico and Honduras. It will be placed on the list between Plain-capped Starthroat and Blue-throated hummingbirds.
The Pine flycatcher (Emidonax affinis) was found in 2016 in the Santa Rita mountains in Arizona, where it unsuccessfully attempted to nest with a Cordilleran flycatcher. It will be placed between Dusky and Pacific-slope flyctchers on the ABA list.
There is also a “split” from the Red crossbill (Loxia curvirostra). This newly separated crossbill is called Cassia crossbill (L. sinesciuris). It is recognized as being endemic to the South Hills and Albion mountains of Idaho. Its large bill has resulted from co-evolution with thicker pine cone seeds, mediated by a lack of red squirrels in the region. The scientific name sinesciuris translates to “without squirrels.” It will follow Red crossbill on the ABA list.
Magnificent no more!
The Magnificent hummingbird was named in honor of the Duke of Rivoli, after it was described in the 1920s - the Anna’s hummingbird is named after his wife, the Duchess of Rivoli. It remained “Rivoli’s hummingbird” until the mid-1980s when it was re-named Magnificent. This most recent Supplement has split Magnificent hummingbird into the Rivoli’s and Talamanca hummingbird (the latter is found in Costa Rica)...
This split separates birds of southern Central America from those of Mexico, the U.S., and northern Middle America. Rivoli’s hummingbird (Eugenes fulgens) is found in pine–oak woodlands from the southwestern U.S. south to northern Nicaragua; adult males have a peridot-colored (yellow-green) throat and blackish underparts. Talamanca hummingbird (Eugenes spectabilis) is found in cloudforest and high oak forests of Costa Rica and western Panama; adult males have a turquoise- or teal-colored throat and dark green underparts. The latter was originally named “Admirable hummingbird” by Robert Ridgway, but his suggestion was unheeded. Instead, Eugenes spectabilis has been named for the Talamanca Mountains of eastern Costa Rica.
This split raises the not particularly serious question of what to call a Berylline X Magnificent hybrid, which birders had playfully dubbed “Beryificent Hummingbird”. Berivoli’s? Riviline? Photo: naturespicsonline.com
