I have noticed flocks and flocks of robins in my yard over the last week. I even saw a dozen on Tuesday when temperatures held in the teens at my house. They are all healthy and well, rather fat. Now, it is not uncommon for some to winter here but they usually stay hidden in brush and remain unseen for a while as they forage for berries. If I didn't have access to computer models I would venture to say that the robins are not concerned about the weather in the immediate future but might be gorging themselves for colder weather to come. Since I have access to the long range computer models I would say that birds might be correct. There are signs of a change to dramatically colder weather beginning next Wednesday, the fifteenth after our 'January Thaw' this weekend ends. Observing Mother Nature is fun and can complement the science behind meteorology.
