Title: Doesn't work on herons and buzzards
Review: Purchased 2 Scarecrows to keep herons and buzzards from sitting on the top of our lanai screen (Florida) and the buzzards from poking holes and pulling out the screening. Installed above the lanai. The wind sets off the sprinkler, but the birds just sit there(right in line with the sensor) and the sprinkler doesn't go off. Changed angles and sensitivity, but had 4 herons on the lanai cage again this morning.
