A familiar expression when leaving the company of someone is "Stay/Keep Warm!," a winter substitute for "take care." You may have wondered how our winter birds do it. The basics are Feathers + Food = Warmth. Birds have added some other energy-saving tricks.
A note from the Cornell Laboratory of Ornithology included this link to their 5-step survival guide birds use in winter. The short essay was written by Charles Eldermire who leads the Bird Cams project at the Lab. It includes several links and some pictures.
