Is it true that Feral pigeons commonly transmit serious diseases to humans?
Partly. One reference states it is rare for pigeons to transmit disease to humans, while several peer-reviewed sources describe feral pigeons as vectors or hosts of zoonotic pathogens and a health risk, though mostly via ectoparasites or potential rather than common transmission. The evidence covers part of the claim on both sides but does not settle how commonly serious diseases are transmitted.
