Well, that does explain the persistence. I guess these two are saying, first come, first served. LOL!
It would explain it indeed. But they’re awfully late showing up this year if it’s them. They usually show up in early January and have eggs by the end of the month.
The weather may have been a factor since so many other northern birds we watch are also late this year.
The behavior of these two has been off in every way but I couldn’t get good enough scaps for comparison.
