I have lost fish over 18 inches to herons....I don't think they can swallow
them that large, but they have flown off with them.... the alligator decoy
doesn't work either (nor does the heron decoy)had one visit a few times this
spring, but have only lost goldfish and shubunkins to frogs and snakes.....no
fish taken by herons so far.....Jerri
