This is our shallow bird bath/drink station.
It's actually a ceramic planter pot and saucer, where I have placed the saucer into the top of the pot and filled the saucer with water. Because the saucer fits into the top of the pot snugly, the structure is quite stable.
I have set the planter onto four little ceramic feet, to aerate under the pot and keep the deck from going moldy. I also move it's position slightly, from time to time, to keep the deck clean.
All the birds like to bathe in it. I have placed a small perch nearby, so they can fly on and off the perch to the water.
Most days, the water needs topping up at least 6 times because when bathing they tend to splash the water out of the container.
This style of bird bath is quite deep and the bigger birds love it to drink from or bathe in.
Tuis seem to prefer bathing in clean water and, within minutes of me changing the water each day, one will be down for a bath. They throw themselves into the water with gay abandon and it's glorious to see.
We have two of these baths and have placed several perches near to each one, because of the birds' preference for jumping into the water, sitting on a perch to preen, then jumping back into the water, preening again and so on. We have counted Tuis jumping into and out of the water 11 to 15 times per bath time.
When there are baby birds around, we have had to rescue several tiny sparrows from this bath, because they are too small to get themselves out of it, and they become exhausted.
