I get a few juvenile starlings visit my garden and I’ve heard what sounds like one of them coughing/sneezing a couple times, of course I can’t be sure it’s the same one but when it does sneeze it’s in bursts not just once so I was starting to get concerned. It’s feathers seem fine and no food around it’s beak and doesn’t seem lethargic but I was wondering if maybe it had some respiratory issues? I know there’s not much I can do and I am regularly cleaning my feeders in case it is infected but I was wondering if there’s anything else I could/should do?
