eat like a bird
Meaning
To eat very little; to have a small appetite.
Origin
Based on the belief that birds only peck at small amounts of food. Though many birds eat frequently, the image of light pecking led to the idiom meaning “eat very little.”
Notes
Casual, slightly playful. It implies someone eats surprisingly little; can sound teasing or judgmental, so be careful with people sensitive about food, weight, or eating habits.
