I saw what looks like upside down 5 gallon buckets on top of a stand made out of 3 pieces of pvc pipe scattered throughout the salt marsh on the way into jekyll island. Any ideas what they are for? Lady at the welcome center was clueless and one of the turtle nest monitors kind of guessed it had something to do with marsh sparrows but didn't sound to confident in her answer. Don't have any pictures because my phone sucks
