Two adult swallows are roosting their second night in a nest left over from the previous summer. Last night they were nervous as I moved around nearby, but this evening they seem calmer. One flew away only briefly after I took several photos. They vocalized quietly but did not screech loudly as swallows do when they’re alarmed.
They were gone all day, and they haven’t done any exterior construction; however, the nest looks strong already. We can see down feathers inside, so it looks like they’re preparing to raise their young here.
