In my ponds and outdoor tank settings, the cyst stage of waterfleas is nearly ubiquitous in in soil. I think they are moved around at least somewhat by wind. I can not fill a pond, even when freshly dug, without a water flea bloom occurring in relatively short order, even when birds do appear to be frequenting the pond.
