For those who love bird watching, choosing the right bird bath can feel like a big decision that can add visual appeal to your property. Just as important, however, is choosing the right spot for said bird bath. Although a sunlit bird bath might seem ideal to you, placing yours in a spot that is brightly lit could actually lead to some undesired results. As algae thrives in hot conditions, positioning your bird bath in the sun gives it exactly what it needs to bloom and multiply quickly. Yet another unpleasant side effect of a sunny location for your bird bath is that the water will evaporate more quickly, leading to less water for visiting birds.
