Let us see when the goldfinch come back.  I just emptied and cleaned their feeder and put fresh thistle in it.  There was some odd combination of bird feed they were not coming to.  This is the time of the year (early spring) I can see up to two dozen goldfinch at one time–some feeding on the ground on thistle that spills over from their feeder.  Now they are drab looking but they will soon change to normal coloration–males then becoming partly bright yellow.  Let us see how many days it takes them to discover the fresh thistle.
