They seem to be a very intelligent bird with problem solving skills. Those water sprayers, it'll take them a couple times, but they'll figure out where they can't spray and that's where they'll fish. Raccoons have been known to figure out how they work and go over and actually move the spray arm out of harms way. Like in Jurassic Park,..."nature will find a way"!
