To be honest I don't know as I have not put any out for them to try. What I do know is that until very recently I had never seen the local Goldfinches drink even though the bird bath is only a few wing flaps away from the feeders. What changed? A short while ago I bought a bottle of CitroSan.
This is a natural product extracted from oranges. According to the blurb on the back of the bottle - "It is a very good sanitizer against a wide range of pathogens and a stimulant for maintaining natural immunity." A small amount is added to drinking or bathing water.
The day after I added some to the water in the bird bath the Goldfinches started drinking from it.
Coincidence? Who knows?
This is not meant as an endorsement for the product just an observation of what happened in my back garden. Having read of problems with finch diseases on other blogs I wanted something natural, without harsh chemicals, that I could add to the water and spotted this and decided to try it out.
Up until this morning I have only seen two Goldfinches visit at any one time. Today there were six vying for a space on the small Niger seed feeder. Looks as though I will have to buy a larger feeder!
