Is this DECEMBER or Spring??????

I have been noticing some robins out in the yard lately and I thought to myself, "It is way to early to be seeing robins, what is going on?" So Cullen went out to investagate and sure enough, there are tons of the little buggers out. I am confused...and they must be too, because they usually first show up here in February or so but not this year...I wonder what this means, Spring weather, no Winter. Or they just decided not to migrate??????????? Anyone else have any weird thing going on with their "weather"???
