Hummingbirds absolutely love spinklers.
We set one by our flower bed at the ranch and watch them play. They also like flying in light rain. I was standing with the cabin door open when it was raining and one flew up to within 5 inches of my nose and just stayed there looking me in the eye for about ten seconds, turned his head to the side to get a better look and flew around to the other side of the cabin to get a drink from the feeder. I told my husband I felt like I was in a Disney movie......they are wonderful little birds and have incredible memories. We had a feeder in a spot on our cabin, but moved it because the hot Texas sun would heat the feeder too much. Six years later, we would see the birds go to that hanger looking for that feeder.
