An outbreak of Avian Paramyxovirus-1 (PPMV-1) is causing a significant die-off of Eurasian collared doves in southeastern Colorado, specifically near the towns of La Junta and Rocky Ford, according to Colorado Parks and Wildlife (CPW). While the exact number of birds affected is not yet determined, CPW officers are reporting finding “hundreds” of dead doves in the lower Arkansas River valley.

PPMV-1 is a virus that primarily affects pigeons and doves. It can cause neurological symptoms such as tremors and twisted necks, as well as respiratory distress. The virus is spread through contact with infected birds or their droppings.

This isn’t the first time PPMV-1 has been detected in Colorado. In the winter of 2014, the virus was linked to a die-off of Eurasian collared doves in the state. CPW Officer Jordon DePriest stated, “This is something that primarily affects collared doves and pigeons. We want the public to know the reason for the die-off so they don’t have to worry about it.”

Impact and Precautions

While Eurasian collared doves are an invasive species, their presence has become common. They are considered a nuisance by some due to their aggressive behavior towards native birds and potential to spread disease. This outbreak is expected to reduce their numbers, at least temporarily. CPW believes the virus will primarily affect Eurasian collared doves and will likely run its course within a few weeks.

Although PPMV-1 is not known to pose a threat to humans, it can affect other bird species. CPW recommends the following precautions:

• Avoid handling sick or dead birds.
• Keep children, pets, and domestic birds away from sick or dead birds.
• Practice good hygiene, especially after being around birds.
