Still haven't seen one of my residents this year, but the syrup in my two feeders did go down very slowly since I put them out, so there may have been some birds passing through. Just changed them for new stuff, as the first syrup was in there for two weeks. Even with chilly weather, that's pushing it for mold and other nasties.
So you should change the syrup, every two weeks, if its unused?
Something to learn every day lol
