Hello. Well this is no joke. A "couple" of Mallards. I think the male was here solo last summer as there was a male who came while five of us were out in the sun it swam in the pool. He then hung out for a half hour sitting in the grass while some were in the pool all less then twenty feet away. They do all look alike but it seems pretty coincidental. They were here two weeks ago as well. It's all very nice except they shit pretty big on the side of the pool and it makes me wonder what they do in the pool. I think they love it because the chemicals which are used in the pool have no chlorine odor but they are chemicals none-the-less. They seem to drink the water as well. I hope they know something that we do not.
