I’ve not seen a house sparrow in the local desert but they are neighborhood residents, judging by the leaves and fur in this male’s beak I imagine he’s building a nest nearby. We may not be contributing to nesting materials here but I like to think a great many birds in our Irvington neighborhood in Portland grew up in the luxury of a fur-lined nest courtesy of a black lab who seemed to shed her weight in fur each week.
