Several Eurasian collared-doves near El Paso have tested positive for avian paramyxovirus, specifically Pigeon Paramyxovirus-1, or PPMV-1, according to the Texas Parks and Wildlife Department (TPWD).
Dead doves have also been reported in Alpine.
The agency said past outbreaks have been observed in the vicinity of many of the larger urban centers of the Trans-Pecos and Panhandle regions such as Midland, Lubbock and Alpine, but outbreaks may occur elsewhere within these regions. The majority of PPMV-1 outbreaks in wild birds in the United States have involved Eurasian collared-doves and rock doves (pigeons).
Symptoms include doves becoming lethargic and reluctant to move, producing green diarrhea or having difficulty standing or holding their head upright. The virus can cause conjunctivitis, also known as pink eye, in humans. Therefore, TPWD said if you encounter multiple dead or dying doves, do not handle the birds without hand and eye protection.
There is no known risk to cats or dogs from PPMV-1, but TPWD recommends keeping pets away from infected birds.
Some strains of PPMV-1 have been shown to cause disease and death in domestic poultry. Chickens can contract the disease from indirect contact, such as dove feces in chicken feeding areas.
Backyard chicken owners may want to take precautions to minimize potential contact between chickens and doves, agency officials noted.
If an outbreak occurs in your area, TPWD recommends discontinuing bird feeding and watering activities to decrease possible transmission between doves and other birds.
If multiple sick or dying doves are located in your area, contact a local TPWD biologist or Don Kahl at don.kahl@tpwd.texas.gov or 806-475-1308.
Officials encourage people to use protective gloves, masks and glasses if handling sick or dying birds in these areas.
