At 1am Saturday Rod heard screeching. He wasted a lot of time looking for a mouse in the kitchen. The next morning we saw the robins' nest near the top of the porch staircase.
At the bottom stair was the remains of one baby bird.
On the step nearby to the area under the porch were more feathers--remains of the 2nd baby?
Rod said if only he'd known, he could have turned on the light and scared the predator away. A day later he said, if the nest was vulnerable, the predator would have just come back, eventually.
The robins had a nest in the same place and raised two broods from it last summer. This brood was the second one of this summer.
