Healthy Feeding Practices: The below 5 steps will help reduce window collisions and disease transmission
Feeder Disease Alert: None noted at this time
1.Regularly clean feeders
The most effective way to clean bird feeders is a combination of washing with dish soap and then soaking them in a 9:1 bleach solution (i.e., 9 qt water to 1 qt bleach) for fifteen minutes. This should be done at least monthly, and if you have extra feeders, rotate them out with dry food as you clean the other feeders. Or put up fewer feeders—only the amount you can regularly maintain—and spread them out to reduce the concentration of birds. Be sure to let the feeders dry out before restocking, and always remember to wash your hands as well.
2. Clean bird baths
Use same solution as above, and try to give fresh water daily.
3. Clean areas under feeders frequently
Keep the feeding area clean by regularly raking up shells and droppings from under feeders.
4. It’s best not to handle sick birds, let your local wildlife agency know if you see sick birds.
5. We can prevent collisions by placing feeders a safe distance (more than at least 35ft) from the house and by applying patterns to the outside of windows.
More on Window Collisions from Joelle Gehring at the U.S. Fish and Wildlife Service
Every year nearly one billion birds collide with glass in the U.S.! Most fatal collisions happen at homes and buildings shorter than four stories tall and windows near bird feeders often kill more birds than windows farther away from bird feeders. Birds do not view glass as a barrier to avoid unless we help them. We can prevent collisions by applying patterns to the outside of windows. Patterns should be ¼-inch in diameter (or larger) and be placed no more than 2 inches apart from each other. Spacing patterns in a 2″ x 2″ grid is especially important for protecting small birds like hummingbirds. You can accomplish this in many ways with different appearances and costs, some are very low-cost.

More on Cleanliness to Reduce Disease:
As bird feeders, we’re more than just provisioning food; it’s our responsibility to ensure that we’re providing a clean, safe environment so these visitors are in tip-top shape when they’re ready to return to their breeding grounds. If we’re not careful, we may unknowingly be aiding the spread of deadly disease.
Scientists have long observed Salmonellosis—infections caused by Salmonella bacteria—in songbirds at feeders. Pine Siskins are especially susceptible to this infection, according to their Birds of the World account, but other birds like House Finches, American Goldfinches, and Evening Grosbeaks can also suffer from the disease. Infected birds show symptoms such as diarrhea, ruffled or fluffed-up feathers, lethargy, and overall weakness, followed by death, and outbreaks can kill thousands of birds in a winter.
Irruptions can put Pine Siskins at higher risk for the spread of these infections. Pine Siskins are generalists who will happily visit bird feeders in enormous flocks during irruption years when they run out of food in the core of their range. However, feeders can have their own dangers. Feeders concentrate birds of multiple different ]species into tighter and prolonged proximity. This increases the chance of disease spreading directly between birds or indirectly through fecal matter or contaminated surfaces. For example, genetic sequencing found that a 2009 Salmonella outbreak among Pine Siskins in the Eastern United States originated with an infected American Goldfinch, and the responsible strain’s distribution was densest where Pine Siskins were most concentrated. It can also affect Common Redpolls when they irrupt in large numbers.
Conjunctivitis is also well known for impacting House Finches, especially in the east, where they were introduced, but conjunctivitis can also affect American Goldfinches, Purple Finches and Evening Grosbeak and others..
Trichomoniasis has hit Purple Finches in the Maritimes and European Greenfinches in Eurasia at various times as well.
If we choose to offer food to these charismatic finches, it’s our job to prevent the spread of disease that feeding stations might exacerbate. If diseased birds are noted, we at the Finch Research Network strongly urge people to take down your feeders for a few weeks, allowing the birds to disperse and feed on wild food sources—especially if you see any suspected cases of Salmonellosis among your visiting birds. If you’d like to continue provisioning food, you should:
We’re grateful that when birds have visited us, now let’s thank them by taking care of them as well as we can.
Feedercam
With the sponsorship of Aspen Song Bird Seed a feedercam for finches went up in Woodland Maine that will hopefully help awareness about healthy feeding practices and also bring wellness for people through watching finches, the most common cohort of birds at feeders perhaps across the world.

The health benefits of watching nature and birds are endless, and more and more studies continue to be published about these benefits, and if there was one silver lining to COVID, it was how people found calm and peace engaging with nature whether by getting outdoors, or even by watching feeders or feedercams. Here’s a link listing several scientific studies about some of these benefits:
