Migratory Songbirds Transport New Ticks & Pathogens Across the Gulf

Excerpt: "An invasion of 19 million ticks. It might sound like the plot of a horror movie, but it’s real, and it happens every spring as migratory songbirds transport ticks — and the pathogens they carry — into the United States.

As covered previously on Cool Green Science, researchers from The Smithsonian Migratory Bird Center (SMBC) and Texas A&M University are trying to figure out just how many ticks and tick-borne pathogens neotropical songbirds are transporting from Central and South America during their annual migration.

And now they have an answer. Their results, recently published in Applied and Environmental Microbiology, reveal that neotropical songbirds are transporting an estimate of more than 19 million non-native ticks species into the country each year."
