noun
Eurasian nuthatch
A small woodland bird (Sitta europaea) known for climbing down tree trunks headfirst. The name is usually written in katakana.
公園でゴジュウカラが木の幹を逆さまに降りているのを見た。
I saw a Eurasian nuthatch climbing down a tree trunk upside down in the park.
Hiragana spelling is also used, though katakana is more common for animal names.
Kanji spelling is rare and mostly seen in older or specialized texts; the word is usually written in kana.
The name 五十雀 (literally 'fifty sparrow') is of uncertain origin; it may refer to the bird's call or an old counting word. The reading ごじゅうから is a kun'yomi compound.
