The homing pigeon flies to me, and the green ring on its foot is where the homing pigeon is.

If the homing pigeon has a green ring on its foot, it may be a homing pigeon in Beijing. The green anklet may be the carrier pigeon anklet in 2006. For details, please check the comparison table of carrier pigeon anklet for confirmation. If you need more accurate information, I suggest you consult the website of the relevant carrier pigeon association or contact local carrier pigeon lovers for consultation. Please note that if the homing pigeon is injured or sick, it is recommended that you provide proper food and water, and consider sending the homing pigeon to the local animal protection organization or veterinary office for rescue.
