In the old apartment we used to live in, we had the chance to set up a solar powered birdbath, and have seen how truly friendly it is to birds, especially when the triple digit soaring summer heat comes in. See the video:

This time around, we have this water feature, a conversation piece at times, looks like a doughnut, a wheel, a life saver, whatever it seems, it adds a cooling effect hearing the water as it trickles down, adding much needed humidity in summer, and sometimes you see some animals enjoying it as well.
This stray cat is taking a sip from the fountain..sorry shot is a bit blurry, trying not to disturb the cat away
Indoors, I have this small fountain, for my small tropicals..
So fountains and birdbaths
