[Tweeters] Any observations of sick birds at feeders recently ?

[Sharon Howard via Tweeters]

This morning I saw a puffed up, slow moving pine siskin on the ground near our bird feeder.  It was slowly pecking at seeds on the ground, but I worried if it were ill.  So, if any of you know of any specific concerns for song birds in the Ballard area, I would appreciate knowing so I can remove our feeders if need be.  Thank you.
