AUSTIN, Texas — Several doves around the state have tested positive for a parasite that can be fatal, according to the Texas Parks and Wildlife Department.
Trichomoniasis is an infectious disease caused by a parasite. It affects mostly doves and pigeons but other species can also become infected, TPWD said, including birds of prey feeding on infected doves.
The disease poses no risk to humans.
Birds affected with trichomoniasis usually appear weak and have a "fluffed up" appearance. The parasite causes inflammation of the crop and mouth and can lead to difficulty swallowing and breathing.
Food and water sources, such as backyard bird feeders and birdbaths, can become contaminated from the mouths of infected birds.
If Texans see sick or dead doves or pigeons on their property, TPWD recommends discontinuing the use of bird feeders or bird baths until affected birds are gone from the area.
All bird feeders and baths should be cleaned frequently using a weak solution with a small amount of household bleach, then rinsed and dried.
Use bird feeders that prevent the seed from getting wet. Parasites are more likely to survive in wet bird seed.
