But I want that one!

At first I wondered why this Lesser Goldfinch didn't go to a lower perch on the feeder.

It saw the seed it wanted and stuck its head into the feeder to get it.  If you look close you can see its head inside the feeder getting some seed.  That is some determination.  Good thing it held on tight with its feet, or it could have ended up inside thefeeder.

I wonder what seed was worth the extra effort?
