I have two feeders one with BOSS, the other has nyger seed. I had a flocks of chikadees and finches. They suddenly left, occasionally I will see a few of each come to the feeders, they peck a little then leave. My trees are full of birds. Should I empty the feeders, and add new seeds? I don't know exactly how I should clean the feeders, the seeds aren't old. We did have a few slight showers last week, is it possible they may be tainted? I have no idea. I would also love to attract the tiny little birds I see in the trees. I don't know what type of feeder or seed. They certainly are not hummers, I can't see them that close, they appear to be dark in color. Also I have some cardinals that cannot feed in my cage feeder, but I also have a huge grackle problem. How should I feed my cards? I live in South Texas. Thank You!

The American Goldfinch is one species with a very long molting period. You may often see some of them at your feeder in all different phase of moilting in the fall and winter. Luc

he is mottled red yellow and orange

Looks like a purple finch. House finches don't have as much red on them. Thanks for posting this. Very pretty bird!
