If you see finches with red, swollen and crusty eyes on your backyard bird feeders and baths, take them down, say Lindsay Wildlife Rehabilitation Hospital officials.
Officials say the hospital sees more cases than normal of the highly contagious housefly eye disease that can cause blindness in finches and some other birds, and the birds come from the whole region.
The best way to prevent the spread is to remove the removed and pray where the disease is ill.
"Type of conjunctivitis is highly contagious," says Aireo Shipman, head of Lindsay's wildlife hospital. "Bird feed and bird bath concentrate many birds so they gather there, and then the disease goes fast."
Shipman says that when birds with the condition are identified by a bird feed or a bath, fodder must be taken down and spilled seed raked up. "Then birds will usually return to feed, reducing the risk of other birds getting the disease," Shipman reduces. "Bird baths must also be taken down and cleaned."
In extreme cases, the disease can cause blindness in the birds. The infection is caused by the bacterium Mycoplasma gallisepticum, which is common in domestic turkeys and chickens. It was first observed in house finke in 1
Lindsay treated 74 cases in 2017 and only 21 last year. But so far this year, 80 birds suffering from the disease have come to the Walnut Creek Center.
The disease spreads through discharge from the eyes and nose and is transmitted when healthy birds come in contact with dizzying birds, which are most common in feeding and bird baths.
Shipman recommends cleaning feed materials and bathing at least once a week or between seed fills or water changes. They should be washed with soap and water, then soaked in a 10 percent bleach solution for 10 minutes. The feet and baths must then be rinsed and dried before refilling.
