Title: Does NOT Work 100% For Heron But Does Deter
Review: Positives of this scarecrow are that it gives the extended family a lot of laughter every time we forget it's there or are doing yardwork and get sprayed by an unexpected jet of water. The miniature dachshund also loves to attack it -- setting the nozzle off which makes her bark and growl even more insanely at it.It has NOT, however, kept a great blue heron from taking fish from our koi pond. Just this morning I found yet another speared (but not eaten) very large dead goldfish laying on the lawn nearby -- seemingly captured by the heron and then abandoned. Since this is the third fish we've lost since installing the scarecrow -- I would suggest it might scare the bird away from consuming all the fish, after it steals one fish, but it does not keep it away altogether.
