“I wish it need not have happened in my time,” said Frodo. “So do I,” said Gandalf, “and so do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given us.”
In the Winter 2022 edition of Colorado Birds, there is a report entitled Occurrence of a Breeding Population of Gray-headed Juncos in Urban Denver, Including a First Confirmed Breeding Record. In the report, the authors detail the occurrence of a breeding population of juncos at as many as five sites in the Hilltop neighborhood of urban Denver. The breeding confirmations in 2021 follow an increase in reports of late-staying juncos in several Denver neighborhoods in recent years, with several of those reports supporting probable breeding. Dark-eyed Junco colonization of urban habitats has been reported in other cities around the country as well. This is a relatively new phenomenon, and juncos are not the only species demonstrating an ability to adapt to urban habitats.
This summer, the authors of the 2021 report have documented: frequent male singing at three of the sites; singing males at other sites in the neighborhood, including counter-singing at one site; foraging pairs at two sites; nest building at one site; and fledglings/juveniles at two sites. Lynne, what you and others have observed appears to be consistent with what has been reported in Hilltop and other urban Denver neighborhoods. Juncos are moving in.
