Eurasian collared dove
While the spread of disease to native species has not been recorded in a study, Eurasian collared doves are known carriers of the parasite "Trichomonas gallinae" as well as pigeon paramyxovirus type 1. Both "Trichomonas gallinae" and pigeon paramyxovirus type 1 can spread to native birds via commingling at feeders and by consumption of doves by predators. Pigeon paramyxovirus type 1 is an emergent disease and has the potential to affect domestic poultry, making the Eurasian collared dove a threat to not only native biodiversity, but a possible economic threat as well.
