- Pigeons who fall ill with pigeon paramyxovirus, a disease also known as PPMV or Newcastle’s Disease, will experience a range of neurological symptoms, such as a violently twisted neck and trembling wings.
- They also dramatically lose weight, have green droppings, walk in circles (often meaning they can’t fly), and are reluctant to move.
