The difference between homing pigeons and ordinary pigeons:

1. Different body shapes: homing pigeons are moderate in size, while ordinary pigeons are large and fat.

2. Different uses: Homing pigeons have the ability to return home over long distances and can fly thousands of kilometers a day, very fast. Ordinary pigeons are used for food and ornamental purposes, but do not have the ability to deliver messages.

3. Different body feathers: The feathers of excellent homing pigeons are tight, dense, thin, elastic, shiny, and supple. The feathers of ordinary pigeons are divided into straight feathers and down feathers. The feathers are wide and suitable for flying; the down feathers are thin and soft, which is good for heat preservation.
