grackle; crow blackbird; oriole (in some contexts)
Refers to birds of the family Icteridae, especially grackles and blackbirds. The gloss 'oriole' may appear in older or less precise sources; New World orioles are in the same family, but true orioles are not. In Japanese, the name literally means 'gray starling mimic'.
The grackle is a black bird commonly seen in North America.
I looked up the grackle family in the field guide.

Kanji spelling is rare and mainly of etymological interest; the word is usually written in kana.
From 椋鳥 (mukudori, 'gray starling') + 擬き (modoki, 'pseudo, mimic'), literally 'false starling', referring to the bird's resemblance to the gray starling.
