A while back I got, on a whim, a sack of birdseed that supposedly finches love. We have a lot of finches around so I hung it and waited for them to flock towards the feast.
This did not happen.
After a while I decided to hang it in a different location. And finally we spotted a finch on it, snacking away! And dang if it wasn’t a truly truly GOLDfinch. I squealed like a small child.
