Different birds prefer different types of food depending on the type of beak they have. A distinction is made here between birds which prefer soft food and those which prefer grain. However, since you should meet the needs of all domestic songbirds in a bird box, you should offer both soft food and grain.
Erinevad linnud eelistavad erinevat toitu sõltuvalt nende noka ehitusest. Laias laastus jagunevad linnud nendeks, kes eelistavad pehmet toitu, ja nendeks, kes eelistavad teri. Kuna söögimajas võiks leiduda toitu kõikidele kodumaistele laululindudele, peaks seal olema nii pehmet toitu kui ka teri.
