Dark-eyed Junco nest in building

Among Oregon birders right now there is some conversation about Dark-eyed Junco nests in atypical locations. My dad took this photo in the late 1950's of a Junco using what appears to be an abandoned Robin nest. Juncos usually nest on the ground in vegetation; Robins usually build their nests in shrubs and trees from 5 to 25 ft. above ground.
