They're eating black oil sunflower seed too, but they spill a lot of that on the ground, possibly through rummaging for the smallest seeds.
I expect the standard sanitization advice is still to wash feeders thoroughly with a 10% bleach solution once a week, paying special attention to crevices where disease organisms may accumulate. Move feeders to new ground occasionally if you can, and stop feeding if you begin to see sick birds. Google "bird feeder hygiene" for lots more on this topic. -Geo -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/[email protected]/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
