Fluffed-up feathers, lethargy, abnormal growths, and crusty eyes are all symptoms of various avian illnesses. If you see a sick bird, there are additional steps you can take to reduce the potential for transmission of disease:
- Clean your feeders and birdbaths more often.
- Consider disinfecting your feeders and birdbaths.
- Consider temporarily removing your feeders. Taking down your feeders could help to disperse birds that congregate in your outdoor space. However, this action is likely to be helpful only if you live in an area with few feeders. If you live in a neighborhood where bird feeding is popular, taking down your feeders could be counterproductive. Removing some feeders could lead to larger congregations at remaining feeders, increasing disease transmission.
- Consider providing additional resources to birds, such as native plant gardens, to encourage birds to disperse from feeders and use more of your outdoor space. Planting native gardens also helps support more resilient ecosystems.
Take action specific to the transmission route of the disease you observe:
- Ocular: If you observe birds with conjunctivitis, take extra care to clean and disinfect tube feeders with ports, as this type of feeder is especially risky for ocular transmission of the bacterium that causes this disease. Using bleach wipes to disinfect tube feeders works very well at reducing the presence of harmful bacteria.
- Oral-fecal: If you observe birds exhibiting symptoms of a disease that is spread via oral-fecal transmission (e.g., salmonella poisoning, trichomoniasis), consider retiring your tray feeders. Tray feeders collect bird droppings that are then consumed by birds that subsequently feed.
