As someone studying redwing nesting and nestlings in the 89-2000 region, I can say they were incredibly variable 3 decades ago. They could easily show up in February when the winter was warm. We had actual females back in a marsh near Binghamton/Endicott as early as February. Usually females did not show up until late march. I don’t mean nest, just be seen in flocks and maybe visit the marsh.
In the years 95 and 97-98, which were incredibly warm winters, we had redwings at feeders being reported all winter—some people were emailing me! In 98, a very warm spring, I had two first year females that were banded on Cornell ponds (by me) back on the ponds in spring…possible explanation was that they never went anywhere all winter and thus failed to disperse. Redwinged blackbird males were also staying all winter or reappearing during the winter in SW Michigan in the 80’s, in warm ups, like robins. Not many but some. These are birds whose migratory pattern set them up well to respond strongly to climatic shifts. No doubt that the mean dates have shifted, but I can look up first arrivals and first egg dates across the 90’s decade at some point, for comparsion—at some point!
