The formel took off from the nest carrying the morning's food drop in her talons. She landed on top of the nearby Civil War monument, a favorite perching and eating spot for all of the FI hawks over the past four years.
In the distance sat the other hawk. It was a stare-off.
Did she leave the nest to distract him from the eyasses? Or was she trying to attract him with her charms, or at least her rat? That she was not in attack mode made it clear that the visitor was male; no nesting formel would ever allow another female near the nest.
This image shows the proximity of the nest on the window ledge (lower left) to the monument on the right with Mom on top eyeing the tiny dot of the other hawk on the highest point of the far building.
She puffed out her feathers in a terrifying way, and was clearly furious at the attempted incursion.
Each time the patient food dropper attempted to get the rat out on the ledge, she launched another attack.
Eventually, the rat was dropped, and after glaring at it for while, she made her grab and took it over to the eyasses on the nest.
The eyasses were sleepily unaware of the day's drama. After she had eaten some of the rat, she took it away...
... and they were left to wake up properly, and explore a bit more of the nest. They are reaching the gawky stage in their prodigious growth where strange body parts hang out at weird angles.
#3, though the youngest, often seems livelier and more alert than the others, craning its neck to see what's happening over the edge of the nest bowl.
Their ET-alien faces now gaze out in dreamy wonder at what lies beyond the nest sticks.
... and then more greenery
The eyasses were visibly tracking her as she flew in and out of the nest.
... closely supervised by the formel.
... and then start peering over. They can probably see the rat out on the ledge.
... and then the day's highlight to see both hawks feeding the eyasses.
