Is Sun or Shade Better?

Locating bird baths right in the sunniest spot in your yard during the summer can do more harm than good. Direct sun can potentially overheat the water and make it less refreshing for birds. It also increases evaporation and causes algae and bacteria to grow more rapidly, which can endanger the health of wild birds and make baths trickier to maintain.

To minimize these issues, the best place to locate baths in summer is in “shade at the hottest part of the day,” says Barbara Gleason, co-owner of Wild Birds Unlimited of Eugene and North Eugene, Oregon. “In some areas, that could mean it’s in the sun early in the morning, but in shade in the afternoon.” Or a spot with dappled light throughout the day could work.

Total shade is okay if that’s what you have, but “it seems as though different species prefer different light levels,” says Rachel Pidgen, environmental stewardship and conservation coordinator at the Wye Marsh Wildlife Centre in Midland, Ontario. Placing your bird bath where it gets direct sunlight for part of the day “could potentially help attract more variety,” Pidgen adds.

While shade during the hottest part of the day is ideal in summer, you may want to move your bird bath around in winter. During the cooler half of the year, it can be helpful to position bird baths in a sunnier spot, which makes baths easier for you and birds to access and also keeps baths from icing over quickly.

That said, sun isn’t the only factor to keep in mind when finding the perfect spot for your bird bath.

Where to Place Bird Baths

Locating bird baths in part shade keeps bird bath water fresh longer and makes sure baths don’t overheat during the hot summer months. But if you want to keep your feathered friends safe and make bird baths even more attractive, here are a few key guidelines to keep in mind.

• Position bird baths near a water source. A location near your garden hose or outdoor spigot makes refilling and cleaning bird baths a lot easier.
• Keep baths near shelter. Hawks, owls, cats, foxes, and other predators can target birds when they’re stopping by baths for a drink. Positioning bird baths within 10 to 15 feet of trees or shrubs ensures that birds can swiftly fly to safety if danger strikes.
• Move baths away from bird feeders. Bird baths should be placed at least 10 to 15 feet away from nearby feeders to keep bird seed and other debris from muddying up the water. For bird health, it’s also best to stow feeders away for the summer as birds usually feed on plants and insects during the warmer months and busy feeders can increase the risk of disease spread.
• Don’t position baths in high traffic areas or where pets are active. Birds are less likely to visit baths that are in areas where you and your pets tend to hang out.
• Keep bird baths away from windows. Positioning bird baths too close to windows can increase the chances of birds hitting the glass. To avoid this, place bird baths far away from windows if you can and consider adding decals to window glass so birds are more likely to avoid it.

Maintaining a Healthy Bird Bath

A bird bath can provide an important source of water for backyard birds year-round. But baths need to be properly maintained to reduce the risk of disease spread and algae issues.

• Clean baths regularly. During hot summer weather, experts recommend rinsing and refreshing bird bath water1 once a day and scrubbing baths clean every few days. In winter, you can reduce this frequency somewhat and clean baths out about once a week.
• Don’t top water off. It’s tempting to just top the level of bird bath water off without replacing the full bath basin. However, this can lead to a buildup of feces and other debris that can make bird baths less safe for birds.
• Watch water depth. Bird baths should be no deeper than 2 inches deep at the center. “Place some rocks in the bath, so that portions of the rock are above the water line. This aids insects like butterflies or valuable pollinating bees to also access the fresh water, which they also need,” Gleason suggests. The rocks can provide birds with a safe place to perch when bathing, too.
• Don’t use bleach or detergents. When cleaning bird baths, skip using bleach, detergents, and other harsh chemicals, which can pose a health risk to birds. Instead, clean baths with a stiff brush and use a 1-part vinegar to 9-parts water solution to disinfect baths as required.
