Robins in Winter?

It's true. There are many more American Robins spending their winters in Maine than most people imagine. Robins can subsist on a diet of berries and other organic vegetation reasonably well providing that they can find water and shelter from cold. Inland, they are most common around wetland areas with  bog-type berries, though a bumper crop of Mountain Ash can sustain them as well. They are more common along the coast where the weather is a trifle more moderate and where many seaside ecosystems support large populations of berries. In fact, it is possible to find immense flocks of Robins - perhaps 500+ - as far north along the coast as Quoddy Head in Lubec, where there is a vast profusion of berries, in temperatures of 20 below!

For any winter, fruit-loving bird, try leaving raisins near your feeders. Let us know if it works.
