As nesting season approaches, young birds will flock to gardens, making feeders a key food source. However, experts warn that dirty or contaminated feeders can spread deadly diseases like finch Trichomonosis, fungal infections, and parasites. Richard Green, a wildlife expert at Kennedy Wild Bird Food & Pet Supplies, shares critical tips to protect birds.
High-Risk Bird Species
Species such as Greenfinches, Chaffinches, Siskins, House Sparrows, and Collared Doves are especially vulnerable. These birds feed in flocks, allowing diseases to spread rapidly through close contact.
Signs Your Feeder Is Infected
1. Conjunctivitis in Birds
Swollen, crusty eyes or lethargic behavior in finches may indicate an infected feeder.
2. Poor Food Quality
Discard shriveled, discolored, or mold-coated seeds, as they can carry harmful bacteria.
3. Overcrowding
Too many birds at one feeder spreads parasites (lice, mites). Use multiple feeders spaced apart.

4. Dropped Food
Discarded seeds near feeders may carry parasites like those causing Trichomoniasis. Clean the area regularly.
5. Damp or Moldy Feeders
Standing water or droppings promote Aspergillosis and Salmonella. Check for mold and clean feeders weekly.
How to Clean Feeders Safely
- Wear gloves and scrub feeders with a diluted bleach solution (1 part bleach to 9 parts water).
- Rinse thoroughly and dry before refilling.
- Clean busy feeders every 2-3 refills; remove feeders for 2 weeks if sick birds are spotted.

Alternatives to Feeders
If maintenance is difficult:
- Install nest boxes for shelter.
- Plant native shrubs for natural food sources.
- Leave wild garden areas undisturbed.
By keeping feeders clean and monitoring bird health, gardeners can enjoy wildlife safely this spring.
Key Takeaway: Clean feeders save lives. Prioritize hygiene to protect flocks from preventable diseases.
