Dust carries the majority of pigeon ailments and it cannot but harm birds that are continually exposed to drawing dust and germs into their systems especially their respiratory tract. A pigeon that is required to fly 500 miles must be able to breathe with complete freedom and take the full benefit of the air it breathes. If not, what chance has it of success? Very little, and no human athlete would have much chance in an endurance test if his breathing system was less than perfect.
