This has been a very slow winter for birds at Mayslake Forest Preserve. The main exception has been a flock of dark-eyed juncos that has taken residence at the former friary site. The area grew a lot of annuals in the late summer and fall, including a number of weedy species, as well as oats.
The seeds from those annuals are keeping these gray sparrows going through the winter. There are enough of them that I doubt that my counts have ever been complete. The high count, in December, was 19. That is many more juncos than I have found on this preserve in previous years.
Juncos tend to establish winter home ranges and stick with them, so I expect to see this flock for several weeks, yet.
