commonly crossed talons, and eagles squared off against falcons and loons, to say nothing of other eagles. This was no different from when wildlife populations had been at their apex before Euramericans swept over the continent. Conflicts and displays of territoriality were common, and sometimes these kinds of events manifested unexpected and even unconventional behavior that not even scientists could explain. The mystery revealed itself most strikingly when eagles at the Upper Mississippi River National Wildlife and Fish Refuge in Illinois gave cam viewers a rousing performance in 2017 of an intereagle conflict different from Ozzie and M-15’s. Five years earlier, a couple named Valor and Hope had occupied a nest at the eighty-foot top of a silver maple. Valor was not the quintessential devoted parent. He was an unreliable provider. After eggs were laid that year, he rarely assumed his sitting duties. When chicks were in the nest and Hope called for him to bring food, he typically ignored her, forcing Hope to leave the chicks in Valor’s capricious care as she herself went off to hunt. At best, he would squat at the nest’s edge for a few minutes before taking flight to wherever whim took him. In the end, Hope could not sustain the brood without a fully present partner, and her two eaglets died. When Hope returned to the nest the next year, 2013, she brought another mate with her. Valor showed up only to find he’d been ousted. He didn’t fight off his rival, which seems consistent with his inertia as a parent. He didn’t leave the eagledom either, and the new mate didn’t chase him away. Hope and her new partner, whom the refuge’s nest stewards named Valor II, remained cordial toward the original Valor. A couple years later, Valor was part of nest life again, alongside Hope and Valor II. Having emerged from his parental torpor, he assumed the responsibilities of a proper partner. The birds formed a threesome. The refuge’s visitor service manager quipped that the upper Mississippi had its “own little soap opera.” In 2015, the couple and their new partner raised three eaglets.44 Parenting trios in the wild aren’t altogether uncommon, although
