Composed of high-quality glass, this bird bath bowl is beautiful yet practical. Its elegance and functionality are sure to delight both humans and birds alike! Choose a shady spot to place the bath, as this can prevent algae growth and keep the water cool. For best results, fill the bath with only 1 to 2 inches of fresh water, as birds can find bathing difficult or dangerous in deeper water. Place gravel, stones, or sand in the bowl to adjust water depth or make the bottom less slippery. Change the water every few days. Hand wash only. Dump the dirty water out instead of adding more to the basin. About once a week or so, scrub the bowl with warm water and soap. Do not use any bleach or other harsh chemicals. Bring indoors during extreme weather. Does not include a stand.
