OK, it wasn't really an argument, but rather three juvenile males fooling around. I originally thought it was a juvenile male attacking Shy and her dad defending her, but after looking at the photos, I could tell it was three male juveniles, including the Tiny look-a-like and the curious very young male (smallest of the three). The curious one was attacked by a slightly older male, possibly "Secret" and the bigger of the three came to his defense. They postured and called to each other while the smallest one moved away. Then, the two older males moved out of the ballfield and play-fought in an open grassy area.
I saw this beautiful female in another field.
No one is using the one large eastern ballfield anymore. I thought it was because of the construction, but I think it might be because of hawks or a falcon scare. They're used to the hawk, but a falcon scares the wits out of them. They may be back there, later, if no hawks or falcons are seen in the area.
George and Martha's Family
Since I came in the late afternoon, I did not see any of George and Martha's family. It's not unusual for that time of day during the last month of two to not see them. They've been staying in the safe area a lot and I don't see them very much. If the lake level gets lower, George and Martha may come back to forage in Alvarado Bay.
