Hope this helps, during the earlier years of my backyard birding I would see finches with eye disease and I became aware of the need for more frequent cleanups. I received the following from NPR’s Birdnote on 1/22. Reduce the number of feeders caught my eye. If you live on the West Coast, please note that a recent die-off of finches (and Pine Siskins in particular) has been attributed to salmonella bacteria. The Washington Department of Fish and Wildlife <https://birdnote.us9.list-manage.com/track/click?u=b766b4da8456d0ed781f5502c&id=92e0ea0bec&e=38489ca349> and wildlife care centers in Oregon and California recommend that you discontinue feeding wild birds for a few weeks. If you do continue to feed birds, please take these steps to keep them safe: Clean feeders daily by first rinsing the feeder well with warm soapy water, then dunking in a solution of nine parts water and one part bleach. Finish by rinsing thoroughly and drying before refilling. Keep the ground below feeders clean by raking or shoveling up feces and seed casings. Reduce the number of feeders you offer to a quantity that you are able to maintain with daily cleaning. Use feeders that accommodate fewer birds (such as tubes rather than platforms), and spread out feeder locations. Keep bird baths and fountains clean. Thank you for doing your part to keep our backyard birds healthy! Annette Pasek Glastonbury
