Never seen these in the yard before and now I have two. Both are very leggy and are using other plants to stay up right. Older Warnock said Verbesina encelioides. Golden Crownbeard
My first time to see these. Best guess on the ID. There was a big flock of dozens out in Brushy Creek Lake. The big flock was too far away for me to get good photos, but there was a pair swimming close to the dam where I was able to get some closer shots.
