Bird Feeding Tips
Tips on attracting and feeding backyard birds.
How do chickadees stay warm in winter – how can we help?!
Many birds, such as chickadees, molt at the end of summer. They may enter the winter with as much as 50% more plumage than at any other time of the year. They also have the ability to fluff their feathers up to increase the thickness of their insulation. However, long winter nights pose an additional problem for chickadees: fewer hours of daylight mean less time for foraging. To compensate, chickadees begin and end their foraging times at lower-light levels and intensify their use of reliably stocked feeders, so that their reduced foraging time is well spent.
In fact, various studies have found that many chickadees that had access to feeders survived the winter. The difference in survival rates was most dramatic during months when temperatures dipped below zero.
