A general term for parrots belonging to the Psittacidae family, subfamily Micropsittinae. They are the smallest of the parrots, with a total length of only 8-10cm. Their tail feathers are short and horny, and their feather shafts are hard like those of a woodpecker, so they have the habit of climbing tree trunks and large branches. The name "parakeet" comes from their similar habits to those of a woodpecker. They live in small groups in tropical rainforests, catching insects from between the bark of trees and digging out adult and larval termites from their nests in the trees with their beaks.

オウム目オウム科ケラインコ亜科Micropsittinaeに属するインコ類の総称。オウム科の中でもっとも体が小さく,全長8~10cmしかない。尾羽は短い角尾で,羽軸がキツツキ類のようにかたく,樹幹や大枝をよじのぼる習性がある。ケラインコの名も習性がキツツキに似ていることによる。熱帯降雨林に小さな群れをつくってすみ,樹皮の間から昆虫類をとったり,樹上のシロアリ類の巣から成虫や幼虫をくちばしでほじり出して食べる。
