When the seeds germinate into wheat or ehatever if its not in way I allow to ripen and then put stalks on my bird table.
We have gold finches, blue, great tits, This year there have been a couple of nuthatch, Their antics are also very amusing. Just had 3 starlings visiting, Mr Robin (very bossy) and wood pigeons who walk around under the feeders eating the detritus from the other birds. Also I think Black caps but not sure. Have not seen Chaffinched this year and blackbirds hop around on the fencebut don't visit at moment.
I do feel lucky about the goldfinches as at last house we saw them but they never visited.
