Some lists: 10

Five (and five more) obsolete common names for birds, taken from the index to Richard H. Pough, Audubon Bird Guide: Small Land Birds of Eastern & Central North America from Southern Texas to Central Greenland, 1946 and 1949, and their modern synonyms.

Lichtenstein’s Oriole
Altamira Oriole (Icterus gularis). M. Heinrich Lichtenstein (1780-1857) was honored by Johann Wagler by naming the oriole for him.
Bandit Warbler
Common Yellowthroat (Geothlypis trichas). The old name has a lot more mojo.
Batchelder’s Woodpecker
Downy Woodpecker (Picoides pubescens). Another eponym that perhaps was a casualty of lumping species together, in this case Gairdner’s Woodpecker, Nelson’s, and Willow.
Cham-chack
Red-bellied Woodpecker (Melanerpes carolinus). I’d say, “like it sounds,” but the bird doesn’t sound like that at all.
Forest Chippy
Worm-eating Warbler (Helmitheros vermivora). Described in the field guides as having voice like a Chipping Sparrow.
Grease Bird
Gray Jay (Perisoreus canadensis). Along with several other equally uncomplimentary names.
Huckleberry Bird
Field Sparrow (Spizella pusilla). Apparently a preferred nesting substrate.
John-chew-it
Black-whiskered Vireo (Vireo altiloquus). This name-sayer name actually works. It’s also known as Whip-Tom-Kelly. Poor Tom.
Pork and Beans
Common Nighthawk (Chordeiles minor). Yet again, supposedly onomatopoetic. I don’t hear it.
Flame-crest
Golden-crowned Kinglet (Regulus satrapa). Another case where the old name is short, descriptive, and to the point, while the new one reads like a committee report. Sort of like the difference between the original Metro station names and the hyphenated jawbreakers we have today.
