Due to the weight of water most hanging baths are smaller than other designs. Small baths are more attractive to small birds. They feel safer in them, in the same way that small children feel safer in a baby pool than they do in full-size swimming pools.
Smaller birds can be enticed to use in the baths by adding stones or gravel to further decrease the overall depth of the bath, creating a water level of 1 inch or less.
Hanging baths are great for patios and balconies where space is at a premium.
Hanging baths can feature decorative designs as well as providing for the birds. Their small size makes them easy to clean but they may need to be refilled more often than larger units.
