Migratory birds facilitate the dispersal of ticks and pathogens

Research indicates that birds serve as ecological bridges for the movement of ticks, potentially introducing exotic species and novel pathogens to new regions. A study conducted along the northern Gulf of Mexico examined the microbiome of immature neotropical tick species parasitizing migratory songbirds.

Researchers identified 421 individual ticks from 28 songbird species, with Amblyomma and Amblyomma longirostre being the most abundant. High-throughput sequencing revealed that Proteobacteria was the most abundant phylum in the microbial profiles, with Rickettsia and endosymbiont Francisella, Candidatus Midichloria, and Spiroplasma identified as the most abundant pathogens.

Additionally, studies into avian parasites suggest that while less common than in some other bird species, doves can carry ticks. The extent of this carriage and its implications for disease spread are subjects of ongoing ecological study.
