Bird Bath Do’s and Don’ts

SIZE AND SHAPE

Make sure the bird bath isn’t too deep. A saucer shaped basin that is 1’’ deep on average with a 2’’ deep middle is recommended by several Ornithology organizations and wildlife departments across the country. Height does not appear to be preferable across all bird species. My personal observation on bird bath height and bird use is that height likely isn’t a driving factor in birds using the bath. Many birds have natural tendencies and behaviors, but if the rest of your bird bath set up is right, they will likely adapt to the height you have. Many birds bathe in puddles on the ground, so do not get caught up in the height of the bath. My suggestion if birds are not using your bird bath is to first attempt to fix all other factors like predation, ease of use, and cleanliness first, and then consider height if nothing changes afterwards.

MATERIALS

Glazed or smooth texture bird baths may be slippery for birds and can be hard to clean. Adding rocks can create a less slippery surface. Concrete baths provide a grippy texture, but may crack if temperatures drop below freezing. Feel free to add rocks and branches across the bird bath to give birds and other wildlife a spot to drink water without getting wet.

HABITAT

Birds are prey animals, so keeping the area around the bird bath clear from thick vegetation is preferred to prevent predation from cats or other predators. Your entire yard doesn’t need to be clear, but just enough space to give a bird time to escape any predators lurking in the shrubbery. Some authorities say 10 ft but I think it likely varies by plant and site selection. Adding food sources for your birds with feeders, plants, and open canopy trees like walnuts can all increase likelihood of use. When temperatures rise, keeping the bird bath in the shade is a good way to help keep birds cool. Animals are drawn to moving water because it its more likely to be fresh. Consider adding fountain features like drippers or misters that can add appeal.

HYGIENE

It is recommended to change the water every day and scrub out the bath at least every two weeks. Many authorities recommend staying away from any water additives or harsh chemicals that are supposed to control mosquitos or algae as we don’t know the full effects on birds.
