How can you clear water on the lungs of an aduld duck after nearly drowning?

To clear water from the lungs of an adult duck after nearly drowning, first gently hold the duck upright to allow gravity to assist in draining water. You can also encourage the duck to cough or shake by lightly tapping its chest or gently squeezing its body to help expel any trapped water. If the duck is still having difficulty breathing, it's essential to seek immediate veterinary care for further assistance and treatment.
