My grandmother talks to her pet bird every day.
The type of food differs between cage birds and wild birds.
野鳥 refers to birds living freely in the wild, while 飼い鳥 refers to birds kept as pets or livestock.
Standard spelling with okurigana; the most common written form.
Abbreviated kanji spelling without okurigana; seen in some contexts but less common.
Compound of 飼い (kai, 'keeping, raising') + 鳥 (tori, 'bird'), with rendaku voicing of tori to dori.
