The Right Way to Clean a #BirdBath (and #KeepBirdsSafe)

#BirdBaths can build up with potentially harmful bacteria, pathogens, and algae if not cleaned properly.

"Bird baths give our feathered friends a peaceful refuge to hydrate and preen, but proper maintenance is needed to keep them welcoming and safe. Since the water in a bird bath is typically stagnant and not naturally filtered as it is in a stream or pond, it can accumulate potentially harmful bacteria and other pathogens. Regular cleaning and water changes help prevent stagnant water that can breed mosquitoes and reduce the spread of disease among birds. Bird baths may need more frequent refreshing during hot weather, periods of algae growth, or times of heavy bird activity.

Cleaning your bird bath—and filling it with fresh water regularly—will ensure it's safe for the birds that drink from it and use it to clean their feathers. Here's how to do it.

How Often to Clean a Bird Bath

How often you clean your bird bath depends on a few factors, including the weather, how frequently it's used, and where it's located. Generally, you should clean your bird bath every two to three days, or more often if the water looks cloudy or dirty. More frequent cleanings may also be necessary if it's hot outside or if the bird bath is under a tree.

"Clean your bird bath more thoroughly every week or so by scrubbing it with a vinegar solution and letting it dry before refilling it," says Tod Winston, a birding guide and urban biodiversity specialist at New York City Bird Alliance.
Materials Needed

Make sure you have these materials on hand before getting started.

- Rubber gloves
- Scrub brush
- Hose or bucket
- Water
- Distilled white vinegar

Steps for Cleaning a Bird Bath

While it's important to replace your bird bath water and rinse away any debris every other day, you should also complete a deep clean of the bird bath once a week, following the steps outlined below.

1. Discard Old Water

Start by putting on a pair of waterproof gloves to protect your hands when cleaning. "Pour out the old bird bath water and large debris into a nearby flower bed or lawn, where it will drain into the soil and not accumulate," says Winston.

2. Rinse and Scrub

Once the dirty water is removed, rinse the bird bath out with a hose or bucket of clean water. Scrub any lingering debris with a brush. Note that the type of brush you use depends on the material of your bird bath.

"For the lightweight plastic basin I use in the WarblerFall, I have learned the hard way that a wire brush, which works well on hard ceramic, will score it badly," says Julie Zickefoose, bird expert and creator of the DIY WarblerFall bird bath. "Algae then gets in the scratch marks, and you can't get it out." For delicate materials, consider a nylon dish scrubber or a cleaning eraser.

3. Clean With Vinegar

Next, mix a solution of 9 parts water and 1 part distilled white vinegar, says Winston. Dip a scrub brush into the cleaning solution and scrub the bird bath, focusing on areas with heavy algae buildup.

Do not use soaps with synthetic ingredients, such as common dish soap, to clean your bird bath, as the chemicals can strip the oils off the bird's feathers.

4. Rinse and Refill

After scrubbing the bird bath, rinse it with water to remove the vinegar solution. "Let it dry in the sun to make sure any remaining vinegar has evaporated," says Winston. Once the bird bath is dry, refill it with fresh water.

Tips for Maintaining a Bird Bath

There are a few measures you can take to reduce how often you need to replace the water in your bird bath and keep it sanitary between deep cleans.

- If possible, place your bird bath in the shade to keep the water cool, reduce evaporation, and slow down the growth of algae and bacteria, says Winston. The best area for a bird bath is near, but not directly under, a low shrub or tree. [Plus it gives the birds a place to perch if someone is already in the bath]
- If your bath has rocks, keep a reserve pile of flat rocks to switch out and set the dirty ones in the hot sun to bake, says Zickefoose.
- Generally, your bird bath water should be no more than 2 inches deep. "Deeper water is less comfortable for smaller birds to wash and preen, and is harder to keep clean," says Winston.
- Always replace old bird bath water completely rather than just adding more water to a dirty bird bath.
- Consider adding a running water feature to your bird bath, either with a fountain or a simple, slow trickle from a hose. "The sound of moving or dripping water is very attractive to birds, and water movement will also discourage mosquitoes from attempting to breed," says Winston."

"Let’s start with the classic: “should you even feed birds?” The easy answer is “Yes,” but it is important to acknowledge that this comes with more responsibility than I think most people are aware of. Primarily, if you are going to be feeding birds, you need to also make sure that your feeders and the seeds in them are clean, generally kept dry, and are not going to be harmful to the birds. Cleaning the feeders once every two weeks is typically adequate to ensure that no bacteria is growing or to help prevent disease from spreading, but this will vary. If it is warm or wet, you’ll want to clean more often, or if you are seeing a sick bird at the feeder, like one with avian conjunctivitis, then you’ll want to clean the feeder and maybe pause feeding for a week or two."

Three Easy but Important Ways to Keep Your #BirdFeeders Disease-Free

Make sure you're helping, not harming, your feathered visitors with these simple steps.

"Feeding birds is a wonderful way to help avian visitors fuel up for migration or make it through a tough winter. It can also provide great opportunities for wildlife photography and observation. But it’s not enough to put out a feeder and fill it regularly. You need to clean it out, or you risk inadvertently causing the birds that visit to get sick. The same goes for #birdbaths.

"Some of the more common diseases that birds can spread through feeders include #HouseFinchEyeDisease (the colloquial name for mycoplasmal conjunctivitis, which can infect more than just the bird for which it’s named), #salmonellosis (caused by salmonella bacteria), #aspergillosis (a fungal respiratory disease), #AvianPox, and #AvianFlu. If you see a sick bird or one you suspect died from a disease outbreak, don’t pick it up or try to treat it yourself. Instead, contact your local #WildlifeRehabilitator or call the National Wildlife Health Center for instructions.

"To prevent the spread of illness in the birds that frequent your seed buffet, try these three steps:

1. Clean feeders regularly
The National Wildlife Health Center recommends cleaning bird baths and feeders with a solution of nine parts water to one part bleach. (If there is visible debris, such as feces, scrub it off before soaking in the bleach solution.) Dry out the feeder before hanging it back up. Project FeederWatch, a joint effort between Cornell Lab of Ornithology and Birds Canada, recommends cleaning seed feeders every two weeks or so. Double the frequency of cleaning if you suspect the presence of disease at all. It's always better to be safe than sorry.

2. Tidy below the feeder
This can mean raking or shoveling up feces and hulls (seed casings)—particularly those that are moldy, wet, or spoiled—and throwing them out, Project Feederwatch recommends. That’ll also help prevent scattered food from attracting rodents. On snow-covered lawns, scraping off a few layers of white stuff should do the trick.

3. Share the wealth
Disease spreads more easily in confined spaces and when groups are concentrated, so having multiple feeders can help prevent disease. Spreading out food among a few feeders provides less opportunities for sick birds to touch and contaminate others, says the National Wildlife Health Center."

Focussing on one of those vulnerable species that we won’t find on a local walk. A particularly iconic and highly vulnerable example, here in Canada, are Caribou - in Europe these are Santa’s Reindeer, and who wants to see them going into extinction or living out diminished lives in sanctuaries and zoos.
